Keruing gunung ( Dipterocarpus retusus ) is a non-timber forest product (NTFP) as a fruit producer that can be used as raw material for vegetable fats. One of the problems faced in planting programs for both production and conservation forests is the presence of fruit pests. The purpose of this study was to determine the fruit pests infestation fruits of D . retusus and the effect of altitude on fruit size and weight in Batulanteh Sumbawa. Fruit samples were collected at locations with different heights, namely below 1000 masl ( T 22oC, RH 83%) and above 1000 masl ( T 20oC, RH 88%). The samples of invading pests were observed and measured morphometry and morphology. The results showed that the insect infestation on the fruit was Alcidodes crassus . The percentage of fruit severity level reached more than 50% at each location. Elevation has a significant effect on fruit diameter and fruit weight, both infested by pests and whole fruit.

Dipterocarpaceae is known as a very important tree family both biologically and economically. Its distribution around the world covers the areas of Peninsular Malaysia, the Philippines, Sumatra, Kalimantan, Java, Sulawesi, Maluku to Papua. Dipterocarpaceae family has a high economic value, such as producing wood, balsam, resin, charcoal, fat, fruit, bark, essential oil, and camphor. Its products have very important roles for domestic use and export needs. As representatives of Dipterocarpaceae, the economic value of Shorea Roxb. ex Gaertner f, Dipterocarpus Gaertner f, and Dryobalanops Gaertner f will be discussed. Considering the very important role of Dipterocarpaceae, both biologically and economically, it is necessary to handle it sustainably, through the following actions such as conservation of genetic resources, seed physiology, seed handling, seedling ecology, root symbiosis and nutrition, pest and disease, management of natural forest, and plantation, and also non-timber forest product from Dipterocarpaceae. Dipterocarpaceae dikenal sebagai famili pohon yang sangat penting baik secara biologis maupun ekonomis. Penyebarannya di seluruh dunia meliputi wilayah Semenanjung Malaysia, Filipina, Sumatera, Kalimantan, Jawa, Sulawesi, Maluku hingga Papua. Famili Dipterocarpaceae memiliki nilai ekonomi yang tinggi, seperti menghasilkan kayu, balsam, damar, arang, lemak, buah, kulit kayu, minyak atsiri, dan kapur barus. Produk-produknya memiliki peran yang sangat penting untuk kebutuhan domestik dan ekspor. Sebagai perwakilan Dipterocarpace, nilai ekonomi Shorea Roxb. ex Gaertner f, Dipterocarpus Gaertner f, dan Dryobalanops Gaertner f akan dibahas. Mengingat peranan Dipterocarpaceae yang sangat penting, baik secara biologis maupun ekonomis, maka perlu dilakukan penanganan secara berkelanjutan, melalui tindakan-tindakan seperti konservasi sumber daya genetik, fisiologi benih, penanganan benih, ekologi semai, simbiosis dan nutrisi akar, hama dan penyakit, pengelolaan hutan alam, dan perkebunan, serta hasil hutan bukan kayu dari Dipterocarpaceae.

The growth of pulp and paper industries has encouraged the expansion of the industrial plantation forests for pulp wood. The exotic species planted for pulp wood initially maintained a relatively high productivity, however it decreases in the following rotation cycles. The peat land wood species of Sumatera could be an alternative for exotic species. However, the insufficient information on the wood properties has brought about they are less considered. This paper examined the fiber quality of Sumatran local peat-wood and its possibility as a raw material of pulp and paper. For specific gravity, samples were selected based on three different diameter groups in each plot. Fiber properties (dimension and fiber derivative values) used to asses the suitability of the wood for pulp and paper raw material were determined in accordance with the method of the Forest Product Laboratory (FPL). The resulted data and information were compared to those of krasikarpa (Acacia crassicarpa Benth.). The results showed that the fiber quality of sekubung wood was classified into grade II, while gerunggang and mahang putih were classified into grade III. The specific gravity of gerunggang wood was higher than these of other woods and comparable to that of krasikarpa. Although the growth of Sumatran local peat-wood is still low, however, conformity with government regulations (Government Regulation Number 57-2016 and Ministry of Environment and Forestry Regulation Number 17-2017) and fiber quality, the local peat-wood could potentially substitute the exotic wood species.

The successful rehabilitation of Wanagama teaching forests, which began in the late of 1960s, has created a distinctive forest ecosystem. Currently the forests become the habitat of Apis cerana, enterprised by the surrounding villagers to produce natural forest honey as a non-timber forest product. This paper aims to explore the adoption of smallholder beekeeping of A. cerana, the beekeepers’ socio-economic characteristics, the potential and value of forest honey production, the distribution of bee-boxes inside the forests and potential tree sources of nectar and pollen. Data collection was carried out in July - September 2019 with in-depth interview techniques to 38 beekeepers. Field observations and ground checks were carried out on the sites where beekeepers were placing the bee-boxes in the forest. In addition, an analysis of aerial photograph images taken with drone was also carried out to identify the area of trees as sources of nectar and pollen. The results show that between 1982 and 2019 the development of the adoption of the A. cerana beekeeping increased significantly. The total production of honey from 506 bee-boxes reached 658 liters or 894.9 kg in year of 2018/2019. The number of bee-boxes placed in Wanagama was mainly distributed inside Compartment of 13, 17, 14, 16, 5, and 18. Acacia mangium, eucalyptus, cajuput and mahogany were the main types of nectar-producing trees, in addition to the abundance of flowering undergrowth plants. Many of the challenges faced by honey beekeepers included climate change, the shortage of nectar and pollen sources, pests and diseases and human disturbances. This research suggests the need for a social, institutional and technical approaches to increase the forest productivity as sources of nectar and pollen. It is suggested encouraging the smallholders to adopt beekeeping as the main livelihood alternatives in future and planting more trees in Wanagama forests.

Nyamplung (Calophyllum inophyllum) is a potential type of non-timber forest product (NTFP) with high oil yield which is useful as an alternative renewable energy sources and herbal medicine-cosmetics. Result of population selection level in Java Island have been used to build Provenan Seed Stand (PSS) nyamplung in KHDTK Wonogiri (Central Java) as an improved seed source with high oil yield and fruit productivity. Seed become nyamplung part that is used as oil raw material which is strongly influenced by flowering and fruiting period. Information on flowering fruiting ability and period is needed to support the availability of raw materials in a sustainable supply for the nyamplung oil industry. Seed become nyamplung part that is used as oil raw material which is strongly influenced by flowering and fruiting period. Information on flowering fruiting ability and period is needed to support the availability of raw materials in a sustainable supply for the nyamplung oil industry. Observation of flowering and fruiting period focused on 465 individual trees in nyamplung PSS at KHDTK Wonogiri through monthly monitoring by calculated flowering fruiting individual tree during 5 years (2014-2018). The results showed that the flowering period of nyamplung in TBP Wonogiri varied during 2014-2018. Flowering and fruiting occurs almost throughout the year. However, the peak of flowering and fruiting occurs mostly in March-August (end of the rainy season to the middle of dry season). In general, the trend of flowering and fertilization increased in 2014-2016, then decreased in 2017-2018, which is thought to be influenced by the higher canopy density. The environmental factor that most influences flowering is number of rainy days, while fertilization of TBP was strongly influenced by temperature. The management of TBP require future action such: second thinning, top pruning, application of fertilizers and hormones to stimulate flowering, and further detailed observations of flowering fruiting stage and its interaction with microclimate.

Copaifera oleoresin is an important traditional non-timber forest product in the Amazon; however, the Carajas National Forest has no plans to harvest this product to benefit extractive families. The objective of this study was to determine Copaifera oleoresin extraction potential in the Carajas National Forest, Eastern Amazon, identifying variables that could increase the chances of finding oleoresin. We mapped 129 trees and formulated a multiple logistic regression model (logit) with the collected variables: diameter at breast height (DBH), tree crown, tree health, presence of termites, and presence of damage or bifurcation. Among the mapped trees, we perforated 50 trees to harvest the oleoresin. Most of the oleoresin production occurred in trees with a DBH between 50 and 75 cm. The logit model predicted that an increase in DBH, dense crown, unhollowed trunk, and presence of damage or bifurcation increased the chances of oleoresin extraction, whereas termites did not. The model could contribute to the sustainable management of forest resources by avoiding random perforation of trees and establishing rational routes and cycles of extraction. Since the variables are easily measured, the model can be continuously used for future extractions.

Known locally as the the lightning mushroom or tiger milk mushroom, Lignosus sp. is well-known as mushroom. Lignosus sp. is categorized as nontimber forest product which has potential to be developed due to its advantages. Interview and literature review were carried out during this study to investigate the ecology, ethnomycology, and economic potential of Lignosus sp. Study result showed that currently the fungi Lignosus sp. in Kotabaru Regency can be found around the forest area that is administratively included in the Muara Urie and Buluh Kuning Villages. Local community has been used this fungi as traditional medicine, such as for cough medicine and postnatal care for mothers. In addition, local people harvest this fungi and sell it to middleman. However, the information of cultivation of this mushroom still limited particularly in South Kalimantan. Therefore, further studies need to be investigate.

The study of utilizing the diversity of non-timber forest product species by testing the value of cultural importance or Index of Cultural Significance (ICS) analysis aims to identify the species of non-timber forest products with highest importance value for local communities. The results of this study documented (1) list of species of non-timber forest products that have an important role in the Malay community in Tanjung Jabung, Jambi, including foodstuffs (51-77 plants), vegetable ingredients (21 plants), medicinal materials (> 77 plants), equipment materials (62 plants), pulp and paper materials (27 plants), and other non-timber forest products; (2) list of species of the potential non-timber forest products to be further developed as fruit-producing plants (12 species), vegetables (10 species), medicinal plants (6 species), pulp and paper-based plants (6 species), plywood (18 species), basic materials for manufacturing equipment, arts and other local technology (8 species); and (3) basic data on economic valuation studies of non-timber forest products. The potential species that have high importance value to be cultivated plants were rambai (Baccaurea spp.), cempunik (Artocarpus hispidum), durian (Durio zibethinus, Durio oxleyanus, and Durio spp.), and rambutan (Nephelium lappaceum and Nephelium spp.) for fruits, rotan jernang (Calamus draco and Calamus spp.) as a medicinal material, and other uses. Specifically the diversity of potential species of non-timber forest products will be discussed in this paper.

Selective Cutting and Line Planting (TPTJ) silvicultural systems and Indonesian Selective Cutting and Planting (TPTI) are two of the five silvicultural systems that have been determined by the Ministry of Forestry Regulation No. P.11 / Menhut-II / 2009 juncto P.65 / Menhut-II / 2014 concerning silvicultural systems in the area of timber forest product utilization permits (IUPHHK) in production forests. Three other silvicultural systems based on the regulation are the Gap Logging silviculture system, the Fully Made Rejuvenation System, and the Multi Silviculture System. This study aims to examine the implementation of the TPTJ and TPTI systems in the PT Intracawood Manufacturing (PT Intraca) area, Bulungan Regency, North Kalimantan. The methodology of this research is through the approach of growth analysis, comparison of stand increment, observation of environmental conditions, interviews and literature study. Based on the field research, it was found that the diameter increments of Shorea leprosula, Shorea dasyphila, and Shorea parvifolia were greater in the TPTJ system compared to TPTI. However, the TPTI silviculture system at PT Intraca is easier to apply in the field than the TPTJ silviculture system. The TPTJ system has become less effective because planting in the TPTJ system has been carried out by making a 3-meter wide track with a length of approximately 1 km in a plot and if there is potential for the wood to become ineffective. In the area of PT Intraca, to improve the effectiveness of the TPTJ system a mosaic system is used where the planting path is made only in areas with less potential and representative for planting. The types of plants planted in the TPTJ system are far superior, perspective, and are faster than the types of plants in the TPTI system. Planting/enrichment in the TPTI system is easier because it does not need to make a planting path. Planting with seedlings from the extraction is only a transfer from the growth of tillers from areas with an excessive potential for tillers.

Previous research on community forestry in Thailand has mainly focused on its institutional dimensions. Comprehensive knowledge on the production of non-timber forest products and on harvesting practices and decision-making processes is therefore still limited, particularly in relation to community-based forestry. A survey was performed to estimate the production of non-timber forest products and to characterize the diversity of harvesting practices and decision-making processes in northern Thailand's community forests. Field investigations were conducted once a month for 12 months in seven community forests in the Lainan sub-district in Nan Province, using a grid-based sampling technique. Production and productivity of the main non-timber forest products were calculated by total fresh weight. In-depth interviews were conducted individually with 231 local harvesters to understand their non-timber forest product harvesting practices and decision-making processes. Young shoots of Melientha suavis, queen broods of Oecophylla smaragdina and edible mushrooms were found to be the three main non-timber forest products collected, with productivity of 2, 12, and 2 kg/ha/year, respectively. Harvesting practices were characterized as applied by (A) landless villagers, (B) small- and medium-sized landholders, (C) larger landholders, and (D) outsiders. Local harvesters displayed different decision-making processes in resource harvesting depending on periods of resource availability, the duration of harvests and the quantities harvested. These quantitative data on resource productivity together with knowledge of harvesting practices and decision-making processes among harvesters will provide input to a participatory resource management process to support exchanges of knowledge among local stakeholders and explore scenarios for appropriate rules of access so as to improve the sustainability of non-timber forest product harvesting.

Rattan cane is an important forest product only second to timber and bamboo, with higher economic value and ecological benefits. Physical and mechanical properties are more important quality performance indexes, which are highly correlated with the processing and utilization of rattan cane. The present paper describes a study of main physical and mechanical properties in different heights of rattan cane for four rattan species, and also makes a comparison of property for Calamus simplicifolius grown in different sites. The relationship between species, cane position, density and mechanical properties of the rattan in China is also discussed. The results show that the physical and mechanical properties differ among four rattan species, and they follow irregular variation pattern with height. The physical–mechanical properties have no significant difference among species except modulus of elasticity, and the same as the different geographical areas. The basic density and mechanical properties gave a more moderate correlation with quadric equation. This result will provide basic data support for property modification and commercial utilization of rattan resources.

Garcinia kola Heckel, called “petit cola” in Cote d’Ivoire and “bitter kola” in Nigeria, is a Non-Timber Forest Product of great socioeconomic importance. Unfortunately, this species is threatened due to overexploitation and deforestation. This study tested the effect of leaf area on stem cuttings to regenerate vegetatively in a non-mist poly-propagator without using exogenous hormones. Three stem cuttings types: greenwood, softwood and hardwood (12 - 15 cm in length) were collected from 24-month years old seedlings. The two top leaves of each cutting type were conserved at different leaf area: 0 cm2, 28.25 cm2, 56.5 cm2, 84.75 cm2 and 113 cm2 (entire leaf area). Observations were made on rooting, sprouting and leafing abilities of cuttings depending to treatments applied. Results showed that all cutting types have presented good ability to shooting and rooting. Cuttings with 113 cm2 leaf areas presented the best rooting (94.44% ± 2.42%) and shouting (95.55% ± 2.42%) percentage and longest primary root length (12.03 ± 0.50 cm). Hardwood, softwood and greenwood cuttings with 113 cm2 leaf area had the best rooting percentage (96.66% ± 3.33%, 96.66% ± 5.77% and 90.00% ± 5.77% respectively). The longest primary root length (13.50 ± 0.97 cm) was observed to greenwood cuttings with 113 cm2 leaf area. Regenerated plants in the forest presented well survival percentage (96.66%). This study shows that it is possible to regenerate entire plants by cuttings without using external hormones in non-mist poly-propagator.

The paper presents the result of the profitability and determinants of the choice of commercialization of non-timber forest products in Kinshasa. This was achieved by means of questionnaire survey administered to 207 vendors of Salacia pynaertii, Gnetum africanum and Pteridumcentrali-africanum. The objectives were to identify the factors which determine the choice of commercializing each non-timber forest product (NTFP) and determine their profitability. Descriptive analysis of all variables collected through the questionnaire survey was undertaken followed by logistic regression of selected factors. Age and marital status determine the choice of commercialization of S. pynaertii, experience is the only explanatory factor determining the choice of G. africanum; age, marital status, market access, place of supply and level of income are explanatory factors determining the choice of commercializing P. centrali-africanum. The results of the daily financial calculations gave the profitability of the 3 NTFPs studied as follows: 5300 CDF (5.7 USD) and 41, 7% for S. pynaertii, 9300 CDF (10 USD) and 86.9% for G. africanum; and 320 CDF (0.34 USD) and 32.2 for P. centrali-africanum.

Growth response of Dendrocalamus asper on elevational variation and intra-clump spacing management. 2021. Title. Biodiversitas 22: 3801-3810. Dendrocalamus asper (Schult. Schult. F.) Backer Ex. K. Heyne is a well-known commodity classified as a non-timber forest product (NTFP) to substitute wood-based products in the future. While bamboo is widely distributed in various habitats, and it could impact growth performance and quality. Nevertheless, the development of bamboo research on the upstream level is quite rare, specifically for clumping bamboo species. Therefore, our study aimed to reveal the performance in elevational variation and to discover the intra-clump spacing and diameter relationship. The elevational variation was divided into three levels, which were lower, middle, and higher levels. Each elevation was established in 9 plots with parameters observed were culm diameter at breast height (DBH), culm height (H), and culm volume (V) of D. asper. The intra-clump spacing was used to assess the relationship between the clump density and diameter growth. The research is complemented with in-depth interviews to explore the traditional silvicultural practices of Dendrocalamus asper and spatial analysis to generate land surface temperature and soil moisture index. The result showed that there is no effect (P > 0.05) of elevational variation to D. asper growth and development, while the availability of intra-clump spacing showed a significant result (P < 0.05) on the culm DBH of D, asper. Furthermore, our result suggests a wider intra-clump spacing (0.4-0.6 m2) is more recommended than a narrow intra-clump spacing for optimal culm diameter growth. Additionally, bamboo plantation was still less managed and utilized. Therefore, improving the productivity of D. asper by maintaining plantation, i.e., fertilizing, managing spacing among clump bamboo, and harvesting to achieve sustainable development of the bamboo plantation is useful.

Quassia amara L. is a semi-sciophyte species that can be found growing as a large shrub or a small tree in Neotropical rainforests. It is traditionally harvested as a non-wood forest product for culinary, medicinal and insecticidal uses. Lack of knowledge on the ecological conditions that support tree growth limits the development of sustainable forest management plans of natural forests and the development of new agroecological cultivation models. The overall objectives of the present work are to (1) compare the Quassia amara L. growth in different forest structures; (2) evaluate the impact of light conditions on Quassia amara L. diameter growth, total height growth and height–diameter relationship and (3) discuss implications for the sustainable management of the species in agroecosystems. Light conditions are characterized at the tree level by the crown illumination index (cii), which is a visual and ordinal index. Results show that tree growth varies between plots with different forest structures and light conditions. The cii was able to characterize light conditions. Best light conditions were different for diameter and total height growth: cii value of 5.0 (tree crown completely exposed to overhead and lateral direct light) and cii value of 3.5 (tree crown exposed to some vertical/overhead direct light and low direct light), respectively. The cii did not affect the height–diameter relationship. A value of cii equal to 4 was found as an intermediate condition and recommended for the establishment of new agroecosystems including the Quassia amara L.

Local Knowledge and Economical Significance of Commercialized Wild Edible Mushrooms in the Markets of Uruapan, Michoacan, Mexico. Wild edible mushrooms are a non-timber forest product of great importance because of their edibility, their cultural and ecological roles, and particularly their economic relevance as merchandise. This study presents a method for the identification of the most economically significant species through a compound index. Fieldwork was carried out in seven markets in the city of Uruapan, Michoacan, Mexico. We recorded the sale of 16 species that constitute 10 local ethnotaxa. Aspects of traditional mycological knowledge regarding systematics, ethnoecology, uses, and collection practices were also obtained. The most significant taxa were Hypomyces lactifluorum, Amanita complex. caesarea, Ramaria spp., and Lyophyllum decastes. We can suggest that the most economically significant species of mushrooms sold in this region are those with the highest supply in markets and correspondingly high profit for collectors. The compound index proved to be a useful tool not only to discover which species are the most relevant, but also to provide explanations for the reasons behind their significance.

Mexican oregano is a non-timber forest product harvested in natural vegetation and represents an important source of income for rural families. Recent reports have highlighted decreases in natural populations caused by increased harvest intensity. Oregano leaf harvesting is a complex problem, involving different components and views, and has a clear spatial dimension. We proposed an analytical framework based on multi-criteria-multi-objective analyses. GIS tools were used as the platform for managing, displaying and analyzing ecological and socioeconomic information from different sources in order to evaluate land suitability of three different management strategies for two competing land objectives: oregano Harvest and oregano Regeneration. The incorporation of environmental evaluation criteria in the analysis allowed the identification of new potential oregano harvesting areas which were neither reported by harvesters, nor registered during harvesting trips. Socio-economic criteria, such as land tenure, highlighted the fact that a substantial proportion of current oregano harvesting areas are located outside ejido limits resulting in potential conflicts for resource access. The proposed Balanced oregano management strategy, in which the same proportion of suitable area (50%) was assigned to both objectives, represents the most favorable management strategy. This option allows harvesters to continue earning an income from oregano leaf harvest; and at the same time helps in the selection of the best areas for oregano regeneration. It also represents a management strategy with a smaller impact on oregano populations and on the harvesters´ income, as well as lower monitoring costs. The proposed analytical framework may contribute to advance the application of systematic approaches for solving decision-making problems in areas where oregano leaves and other NTFP are harvested.

Forests are biological natural resources that have provided development benefits in Indonesia during their specific “Orde Baru” government of the timber forest product sector, but the impact of high exploitation has had considerable damage. Therefore it is necessary to find alternative efforts in forest utilization. One such effort is to utilize plants that can be used as medicinal plants. Medicinal plants are an alternative use of forest products from the non-timber sector. One of the places that need to know the existence of medicinal plants is Taman Wisata Alam Gunung Tampomas. Lack of data from the types of medicinal plants in this area feared damaged and extinction.The results of this research found 21 species of medicinal plants consisting of 19 types of non-tree vegetation and 2 types of tree vegetation. Non-tree vegetation is dominated by the type of Eupatorium riparium with Relative Frequency of 8.60%. While the tree vegetation was dominated by Melia azedarach species with INP value in each strata of seedlings, piles, poles, and trees respectively 9.02%, 11.97%, 18.14% and 20.43%. Most of the medicinal plants have the benefit of fever, abdominal pain, urine, malaria, bleeding such as Imperata cyindrica, Melia azedarach, Ageratum conyzoides, Quassia amara, Angioptris evecta and Eupatorium ripariumBenefit from this research about existence of medicinal plants in the area of Blok Paseban and Blok Pasir Sabeulah TWA Gunung Tampomas, the community can make this area as a source of germplasm so that the existence of medicinal plants can be preserved sustainability. In addition, people around the area can cultivate medicinal plants outside the area of TWA Gunung Tampomas

Bilberries (Vaccinium myrtillus L.), raspberries (Rubus idaeus L.), blackberries (Rubus fruticosus L.) and cowberries (Vaccinium vitis-idaea L.) are the most important forest berries collected in the Czech Republic (CZ). The average annual value of these collected berry species is estimated to be worth more than EUR 86 million at 2018 prices. The data concerning the collection and use of forest fruits have been systematically collected in a highly detailed structure since 2008, which enables the application of the advanced statistical methods used in this paper. The results of the analyses inter alia demonstrate that collecting forest berries is not only an important recreational activity, but it has an important economic effect. Therefore, this article also deals with the collection of forest fruits, especially bilberries, as a potentially important non-wood forest product (NWFP) for sustainable forest management and also analyses the external factors influencing the total annual amount of collected forest berries. A deeper knowledge of the customer and his or her behaviour&mdash, customer insight&mdash, are prerequisites for the proactive management of forest ecosystems. The first step to &ldquo, berry picker insight&rdquo, is to learn more about the demand, its structure and factors which influence this demand. Thus, one of the research questions concentrates on the analysis of the sociodemographic characteristics of the berry picker that are relevant for explaining the amount of collected forest berries in the Czech Republic. Knowledge of these factors can contribute to a more effective application of marketing methods for shaping and influencing the demand so that, in terms of time and place, it is more in line with the supply, which is limited by the natural conditions, growing season and production potential of forest ecosystems.

Pine straw, the uppermost forest floor layer of undecayed, reddish-brown pine needles, is raked, baled, and sold as a landscaping mulch throughout the southeastern United States. Loblolly (Pinus taeda, L.), longleaf (P. palustris, Mill.), and slash (P. elliottii Engelm. var. elliottii) pine are the three southern pine species commonly raked for pine straw. The value of pine straw as a forest product is large. Private landowner pine straw revenues have steadily increased throughout the southeastern United States over the past two decades and now total more than USD 200 million. Information is limited on the short- or long-term effects of pine straw removal on foliage production or stand growth in southern pine stands. Results from most published studies suggest that annual pine straw raking without fertilization on non-old-field sites reduces straw yields compared to no raking. Old-field sites often do not benefit from fertilization with increased pine straw or wood volume yields. Though fertilization may be beneficial for pine straw production on some sites, understory vegetation presence and disease prevalence may increase following fertilization. This review addresses pine straw removal effects on pine straw production and stand growth parameters based on recent studies and provides fertilization recommendations to maintain or improve pine straw production and stand growth and yield.

The increasing rate of land use intensification and the rising evidence of climate change impacts raise concerns about the viability of valued non-timber forest product (NTFP)-providing trees. This calls for the assessment of the current status and future trajectories of their populations. Using population data collected from three land-use types (e.g., grazing lands, riverine areas and natural forest) in western Tigray, we evaluated the vulnerability of the multipurpose baobab tree (Adansonia digitata L.) to human disturbances and climate change. The study was based on the premises that integrating ecological science with modeling tools and local knowledge would enhance the overall effectiveness of conservation strategies and community support. Therefore, based on field-based inventory, ecological niche modeling and a socioeconomic study, we characterized and mapped baobab current and future population distribution and documented local knowledge on the uses and management of the species. The characterization of the population structure showed that baobab stands were denser with larger-sized and taller trees in riverine areas and natural forest compared to grazing lands, suggesting adverse effects of human disturbances on its populations. Moreover, positively skewed size-class distributions with negative slopes in all land-use types indicated a low recruitment of juvenile trees to the adult stage. Climate change simulations using Maximum Entropy Algorithm (Maxent) revealed that future temperature increases would lead to significant reductions (41–100%) in baobab suitable habitats due to range contraction. The intensive harvesting of baobab leaves, branches and bark and lack of conversation practices as indicated by local communities, in combination with the risk of local extinction under future climate warming constitute serious threats for the viability of the species in western Tigray. The results suggest immediate interventions, such as planting baobab at up to 65 m higher in altitude, designing appropriate leaf and bark harvest strategies and protecting seedlings from livestock, will help guarantee the persistence of the species populations.

Biodiversitas 21: 3117-3126. Swiftlet nest is a high-value non-timber forest product produced from the saliva of swiftlet birds. While the demands for this commodity continue to increase in global market, careless harvesting techniques have diminished the swiftlet population and the production of swiftlet nests, threatening its sustainability. One effort to solve this problem is by developing swiftlet farming which involves building swiftlet. This research aimed to analyze the ecology, productivity, and financial feasibility of swiftlet farming of different-sized swiftlet houses in Kota Bangun Subdistrict, East Kalimantan, Indonesia. This research used qualitative and quantitative analysis methods. Data were collected using purposive sampling to determine the location, sample of swiftlet houses, and interviews with respondents. Quantitative analysis on the financial performance of swiftlet farming was analyzed using the net Benefit-Cost Ratio (net B/C), Net Present Value (NPV), Internal Rate of Return (IRR) and Payback Period (PP) methods. The results showed that swiftlet nest production in Kota Bangun begins in the third year and ends between 27 and 45 years later, depending on the age and size of the house as well as the quality of the timber. The swiftlet house with a size of ​​512 m2 had the net B/C of 4.06, NPV of IDR 1,403.79 million, IRR of 30%, and PP of 5.44 years. The swiftlet house with a size of ​​1,600 m2 had the net B/C of 2.27, NPV of IDR 1,774.83 million, IRR of 24.09%, and PP of 9.4 years. Our study suggests that swiftlet farming is financially highly feasible, especially for the swiftlet house with a size of 512 m2.

Adalina Y, Sawitri R. 2020. Vegetation analysis, physico-chemical properties and economic potential of damar (Agathis dammara) in Mount Halimun Salak National Park,West Java, Indonesia. Biodiversitas 21: 1122-1129. Analysing the potential of non-timber forest product (NTFP) plants in Mount Halimun Salak National Park (MHSNP) is one of the important aspects in supporting conservation and improving the economic status of communities around the forest. This study aims to determine the economic potential and benefits of damar plants (Agathis dammara) in MHSNP area of Kawah Ratu Resort, Sukabumi District, West Java, Indonesia along with analysis of damar plant forest and physico-chemical analysis of the copal/resin. The selection of research village was by purposive sampling and the selection of respondents was by random sampling. Forest vegetation in the Kawah Ratu Resort is entirely dominated by damar plants. The Important Value Index (IVI) of damar plant trees is 300% and the density is 582 trees/ha. The quality of copal from Kawah Ratu Resort meets SNI standards in parameters like ash content, soft point and melting point, while the saponification number is above SNI standard. Level of dung in copal chunks meet SNI standards and has better quality than copal in the form of powder. The present average income of farmers from resin tapping is Rp 624,000/person /month, which makes an average contribution of 63.08% to the total household income of farmers. But the actual economic potential of gum resin in Kawah Ratu Resort was estimated to be around Rp 596,920,000/month.

Fraser fir (Abies fraseri [Pursh] Poir) is a popular, high-demand Christmas tree species, making it an important nontimber forest product. Fraser fir is the only endemic fir to the Southern Appalachian Mountains. It is a small to medium-sized tree with a very limited range in upper elevations of western North Carolina, southwestern Virginia, and eastern Tennessee.

Pine resin, a viscous material secreted as a defensive response to biotic or abiotic damage, is a highly valuable non-wood forest product with multiple uses in the industrial sector. Resin production can be induced by tapping live trees, but not all pine species produce resin of suitable quality and/or in profitable quantities. Maritime pine (Pinus pinaster Ait.) is currently the only species tapped in Spain, where resin tapping activity has been recovered in the last few decades. Most studies on resin production focus on the mean production per tree or per area, and less attention is given to determining how the production is distributed across individuals or production classes. We modelled the distribution of resin production in Pinus pinaster stands in Galicia (NW Spain) by using the Weibull function and the moment-based parameter recovery method. We observed a high level of variance in resin production between plots (different sites, stimulants used, tapping method or year) and within plots, between trees. All resin production distributions modelled using the arithmetic mean resin production ( x ¯ ) and the variance of the distribution (σ2) per plot satisfied the Kolmogorov-Smirnov (KS) test, in which critical values were obtained by Monte Carlo simulation. The variance of the distribution (σ2) was positively correlated with x ¯ , and the relationship was described by an exponential model. When resin production distributions were modelled using x ¯ and estimated variance ( σ ˆ 2 ), 7% of the distributions (corresponding to trees in which chemical stimulants were not used) did not satisfy the KS test. The mean production ( x ¯ ) can be easily determined by dividing the stand production by the number of trees. However, x ¯ could also be estimated before commercial tapping by sampling a representative number of trees. We conclude that in order to estimate x ¯ , a minimum sample of 50–60 trees should be tapped, to yield a relative standard error (RSE) below 10%; 10–15 trees should be considered for RSE

Njansang -Ricinodendron heudelotii (Baill.) Pierre ex Pax.- is a commonly traded non-timber forest product from Central African humid forests, used as a spice. South West Cameroon was selected as major production area and market where little data exist on the contribution of njansang to stakeholders livelihoods in the value chain. Interviews were used to gather information from 261 harvesters, traders and processing enterprises. From 2013 to 2015, 65.8 tons were harvested, with 13.17 tons traded in markets in the South West Region and in Nigeria for a value of €33,511. The ease of accessing markets makes a significant difference to the quantity harvested and contribution to harvesters’ household income. Average profit for harvesters is higher in regional markets than in local ones. Harvester’s profits were higher than buy’amsell’ams, retailers and exporters. Processors add the most value and earn the highest unit profits. Livelihood dependence upon njansang decreases along the chain, with harvesters more dependent than traders. Seasonality, corruption, storage and processing, influence price. Long-term value chain sustainability could be improved by increasing collaboration between stakeholders, collective action, disseminating knowledge about processing and storage techniques, and promoting domestication and cultivation to enable trade in this largely wild harvested NTFP to continue sustainably.

Seran YN, Sudarto, Hakim L, Arisoesilaningsih E. 2018. Structural model of sandalwood (Santalum album) regeneration in the forest and community plantation in Timor Island, Indonesia. Trop Drylands 2: 41-47. Sandalwood (Santalum album L.) is a very important forest product in NTT, an endemic species in the world with a high economic value.. This study aimed to identify and produce a structural model of sandalwood regeneration in both the forests and the community plantation in the Regency of Timor Tengah Selatan (TTS) and Timor Tengah Utara (TTU). The method used in this research was vegetation analysis by purposive sampling method on 8 observation stations with 87 plots. The plot size was 20x20 m2 (trees), 10x10 m2 (poles), 5x5 m2 (saplings), and 2x2 m2 (seedlings). Data observed in the field included the mean sandalwood population size in the forms of trees, poles, saplings and seedlings phase, vegetation data in sandalwood habitat which included tree wealth index, diversity index, number of individuals and sandalwood host diversity index data. Geographical factors such as altitude and slope, and abiotic factors such as soil organic matter, soil pH and soil conductivity were also recorded. Climate data included the number of dry months and rainfall. Sandalwood regeneration data included sandalwood vitality, pests and diseases and the number of seeds. Secondary data included climate data (ten years time) obtained from BMKG of NTT Province in Kupang. These data were used as the indicators of the latent variables (six variables) which consisted of geography, soil, climate, population, vegetation, and regeneration. Obtained data were subjected to both descriptive analysis and multivariate statistics with structural modeling of Warp Partial Least Square (WarpPLS 6.0). The results showed that most of the proposed indicators significantly influenced the compiled six latent variables except the host diversity. Some indicators significantly or highly significantly affected the latent variable with 15 indicators that significantly composed the latent variable. The resulting structural model is very relevant and has a relevance value of Q2 prediction of 96,65% so that the structural model proposed in this study has very relevant and high predictive value on factors that influence sandalwood regeneration. Therefore, this model is feasible or appropriate to be used as recommendations in the framework of sandalwood development in the forest and the community plantation in the West part of Timor Island, Nusa Tenggara Timur.

Forest is a resources system which has prospective materials to be used for human needs. Local people within everyday life are very dependent on the natural surroundings, as well as the use of nature for human needs tend to increase. The purpose of this research is to do the analysis of vegetation and determine the potential use of non-timber forest products in Kampung Pagai, Airu District, Jayapura. The method used for the analysis of vegetation is the square plot, while the method to figure out the potential of non-timber forest adopts the method developed by Waluyo (2004). The results showed that there are at least 39 species of trees belonging to the 26 families. Regeneration of trees showed the condition which is good based on the diversity of tree species in the Sapling level, especially matoa (Pometia pinnata), kayu besi (Instia bijuga), and various plants of Ficus ssp. The potential uses of non-timber forest are also quite high. Several types of plants can be used as building materials and accessories, medicines, ornaments (including orchids), fruits, and vegetables. Key words: forest, vegetation, non-timber forest product, Airu District, Jayapura.

Hardwood lumber is the principal part of the global hardwood timber trade. China has become the largest importer of hardwood lumber in the world. However, China’s hardwood lumber imports are affected by price volatility. Thus, we investigated the price volatility transmission of China’s hardwood lumber imports. We aimed to detect the source, path, and intensity of the volatility transmission in China’s hardwood lumber imports, and reveal the intrinsic interactions between price volatilities. To date, there is little research on the price fluctuations of forest products. This paper provides an empirical analysis on the volatility transmission in China’s forest product imports. We selected four types of major hardwood lumber imports to China, that is, teak (Tectona grandis L.F.), merbau (Merbau), sapele (Entandrophragma), and casla (Terminalia spp.) (The Latin names of tree species are given in parentheses), and used their daily prices from 4 August 2010 to 15 April 2020. The Baba–Engle–Kraft–Kroner (BEKK) multivariate models and dynamic conditional correlation (DCC) models were employed. The empirical results indicate that there is an intrinsic relationship between the price fluctuations in China’s hardwood lumber imports. The volatility transmission chain originates from casla, it is transmitted along the casla→sapele→merbau→teak pathway. The direction of transmission is from lower prices to higher prices. The dynamic conditional correlation of each link in the chain does not exhibit any particular time trend. This suggests that volatility transmission is a crucial price mechanism in China’s hardwood lumber imports. Our findings have important policy implications for hedging timber price risks and designing timber trade policies.

UMP�s University forest 4.910 ha with lowland type and peat swamp forest types habitat have many potentials of forest products especially nontimber forest product (NTFP) like latex, resin, honey, traditional medicine and ornamental plant near animal hunting (for stoping program). NTFP is one opportunity of the community to rising of economic values to make a management model for conservation base on the community with more participating to protect the forest. The research method is an NTFP inventory for 2 forest habitats to searching the market opportunity and community focus group discussion (FGD) to combine the data and community assumption. The result of this research Is we can found an effective model of forest protection with economical community participated in our forest for NTFP. NTFP potential in UMP�s University Forest is damar batu (resin), kopal damar (resin), latex of jelutung, rattan and traditional medicine. We need a more fascinating program and socialization activities for the community for other NTFP in UMP�s University Forest. The most productive of 2015-2016 is a resin of Shorea collection by the community with average 50kg/day per collector and average of community income Rp. 125.000,00/day per collector.

Bark of Daphne bholua is an important non-timber forest product and makes a substantial contribution to the Nepalese economy. A precise estimate of the amount of D. bholua bark in mountain forests is possible using a biomass model. We developed an allometric bark biomass model for naturally grown D. bholua in Baglung District in the mid-hills of Nepal. The model was based on data from 101 destructively sampled D. bholua on 20 sample plots representing different growth stages (regeneration, established, and matured), site qualities, and stand densities, and we used diameter and height–diameter ratio as predictors. Among 9 functions evaluated, a simple power function showed the best fit to the data. This model described most of the variations in bark biomass with no substantial trends in the residuals. Leave-one-out cross-validation also confirmed the high precision of this model, because it described most of the variations in bark biomass with no substantial trends in the prediction errors. The model can be applied for a precise prediction of bark biomass for individuals of D. bholua with diameters and height–diameter ratios similar to those used in this study. It is site-specific, and its application should therefore be limited to sites with growth stage, site quality, stand density, and species distribution similar to those that formed the basis of this study. Further validation and verification of this model, with a larger dataset collected from sites with a wider range of these characteristics, is recommended.

Incense-resinous wood of agarwood is a high-value non-timber forest product found in the trunk or branches of Aquliaria and Gyrinops species. Incense-resinous wood of agarwood is formed as a response to tree damage caused by wounding or fungal attack. Detection of such wood in trees has generally been carried out based on natural signs such as dark spots or black marks when peeling back tree bark, but these often yield uncertain results. Sonic tomography can be applied to predict the presence of incense-resinous wood in standing trees. The objective of this study was to evaluate sonic tomography at various trunk heights based on variations in the sound velocity associated with the presence of incense-resinous wood. Ten agarwood trees ( Aquilaria malaccensis ) were selected for this study; five trees were artificially inoculated with Fusarium solani fungus and the other five were untreated. The results showed that the height of the measurement did not significantly affect the propagation velocity of sound waves or the tomographic results. Sonic tomography revealed that prediction of the deteriorated zone which is indicative of incense-resinous wood formation was 1.1% greater in inoculated trees than in uninoculated trees.

The genus Protium Burm f. (Burseraceae) is characterized by having species with the property of exuding resin from tree trunks. These resins have several popular uses. Besides that, they are being used in the cosmetic industry and in scientific studies. Considering the growing demand and the potential of this forest product, it is necessary to develop a sustainable management technique that increases the amount of resin obtained, without altering its quality. This could avoid the product running low on the market and the improper exploitation of trees in the forest, and could turn into a new source of income for extractivist communities. This study aimed to evaluate the influence of the chemical stimulant ethephon on the resin production in two species of Protium at Ducke Forest Reserve, in Manaus, Central Amazonia, Brazil. Another objective was to verify the variation on the chemical composition of the resin hexane extract in Protium strumosum Daly, caused by the use of stimulant, by GC-FID and G...

Summary The harvesting of non-timber forest products (NTFPs) is a global phenomenon, the sustainability of which has been studied for many species at the individual and population level. However, the broader scale impacts of NTFP harvesting have been acknowledged but rarely examined. We assessed plant size and the soil attributes undercanopy and in the open, in replicate, paired harvested and non-harvested sites for three NTFPs differing in the extent of biomass removed, i.e. timber for firewood from a tree (Acacia karroo), fruits from a cactus (Opunita ficus-indica) and flowering culms from a grass (Cymbopogon marginatus). Soil variables tested included pH, resistivity, P, total N, nitrate nitrogen, ammonium nitrogen, K, Na, Ca and Mg. The extent of loss of soil nutrients decreased across the three NTFPs relative to the proportion of biomass removed. Thus, significant differences in more soil variables were evident for the firewood species, least for the fruit species and intermediate for the grass species. Lower soil pH, P, C and K were evident in soils collected underneath A. karroo, while losses in cations of Na, Ca and Mg were reported in soils underneath C. marginatus, and only NO3N losses were recorded underneath O. ficus-indica. Synthesis and applications. Our study reveals that while non-timber forest product (NTFP) harvesting may affect soil nutrients, this is not uniform between species and is likely to be a function of the extent of biomass removed and harvesting frequency. This indicates the need for caution in generalisations about the ecosystem-level impacts of NTFP harvesting as well as a concerted effort to better understand impacts at a greater range of scales than has been the case to date.

Commercial exploitation of wild yams (Dioscorea spp.) was once a pillar of the Mexican economy and is currently practiced in the USA and Asia. However, no such activity has yet been reported in South America, the continent richest in Dioscorea species. Upon discovery of wild Dioscorea tubers in marketplaces in Bogota, Colombia, we sought to (1) identify the species being sold, (2) document the medicinal properties attributed to them, and (3) conduct a preliminary characterization of the market for this product in the capital. During the years 2010, 2012, and 2013, 226 semi-structured interviews were conducted with vendors in 82 medicinal plant stalls distributed in marketplaces throughout Bogota. Tubers of four native species were identified, all wild-harvested: D ioscorea coriacea, Dioscorea lehmannii, Dioscorea meridensis, and Dioscorea polygonoides; all were sold under the generic name zarzaparrilla, with D. coriacea being the most prevalent species. All vendors interviewed recommended Dioscorea spp. for treating “ailments of the blood,” with “blood cleanser,” and lowering triglycerides and cholesterol as the most often-cited specific uses. Total estimates of sales of wild yams over the study period averaged 488 kg/week, extrapolated to over 25,000 kg/year, with yearly sales varying between 5% and 6% around the mean. This is the first report of raw tubers of any Dioscorea species being commercialized for the treatment of blood or metabolic disorders in Latin America, and the data suggest there is a robust market established in Bogota. In the interest of public health, pharmacological studies should be undertaken to test the biological activity of these species and to rule out toxicity. We especially recommend population studies of D. coriacea to provide baseline data for sustainable management of this non-timber forest product.

Background: Predictive models shed light on aboveground fungal yield dynamics and can assist decision-making in forestry by integrating this valuable non-wood forest product into forest management planning. However, the currently existing models are based on rather local data and, thus, there is a lack of predictive tools to monitor mushroom yields on larger scales. Results: This work presents the first empirical models for predicting the annual yields of ectomycorrhizal mushrooms and related ecosystem services in Pinus sylvestris and Pinus pinaster stands in northern Spain, using a long-term dataset suitable to account for the combined effect of meteorological conditions and stand structure. Models were fitted for the following groups of fungi separately: all ectomycorrhizal mushrooms, edible mushrooms and marketed mushrooms. Our results show the influence of the weather variables (mainly precipitation) on mushroom yields as well as the relevance of the basal area of the forest stand that follows a right-skewed unimodal curve with maximum predicted yields at stand basal areas of 30–40 m2∙ha− 1. Conclusion: These models are the first empirical models for predicting the annual yields of ectomycorrhizal mushrooms in Pinus sylvestris and Pinus pinaster stands in northern Spain, being of the highest resolution developed to date and enable predictions of mushrooms productivity by taking into account weather conditions and forests’ location, composition and structure.

Rattan is a non-timber forest product important to both forest biodiversity and local livelihoods in Southeast Asia. In this chapter, we aim to understand the changing patterns of socioeconomic activities in local communities and in the global market, as well as human–nature interactions in Sarawak from the perspective of the transition of rattan utilisation from the past to the present. For the analysis, we employed a multidisciplinary approach using a socioecological survey and historical study, and set three spatial scales as a framework. First, we found that people recognise and make use of various rattan species based on the diversity of surrounding forests. The high diversity of rattan species in these forests supports the preservation of knowledge and culture, and local communities are able to acquire multiple benefits from the forests through rattan. Second, we show the effects of development on traditional knowledge and rattan use by comparing a rural village to villages close to more developed urban areas in which people use a limited number of rattan species because primary forests are no longer accessible. Utilisation of rattans in peri-urban villages has also changed, departing from the close relationship with primary forests that is vital for selecting and using particular rattan species for various needs. Third, we pay attention to the emergence of the regional market for rattan materials provided by a rattan-processing factory in the urban area of Bintulu. In suburban villages, inhabitants who have limited access to primary forests now buy machine-processed rattans for making crafts, possibly leading to a decline of traditional knowledge and the culture of rattan in these communities. Finally, we discuss the trajectory of rattan exports from Sarawak on a global scale over the last 150 years. From the late nineteenth century onwards, rattan exports for the global market enabled local people to gain commercial profits, and we confirm that such a trade connection has lasted through the boom of rattan exports from Sarawak in the mid-1980s. As such, this local to global, past to present study of rattan shows that Sarawak’s highly biodiverse society, which depends on various kinds of natural resources from primary forests, has altered in response to the impacts of the world economy and land-use change over the last two centuries.

Rattan jernang (Daemonorops draco Willd.) is a type of non-timber forest product that has a high market value. To reduce dependence on natural forests, jernang rattan cultivation is important. This study aims to determine the growth response of 3 year old jernang rattan plants to light intensity under mixed stands. The study was carried out at KHDTK Kemampo, Palembang Environmental and Forestry Research and Development Center from June to July 2020. This study used an experimental method with a Non-Factoral Randomized Block Design consisting of 3 treatments with 9 replications. The treatments consisted of P1 = canopy closure 10–30% (light intensity 72.19%), P2 = canopy closure 40–60% (light intensity 55.63%), and P3 = canopy closure 70–90% (light intensity 23.39%). The results showed that the growth of jernang rattan gave a very good response to light intensity under mixed stands for all parameters observed, namely plant height, leaf midrib length and number of leaves, as well as leaf color. The best growth of jernang rattan is in light conditions with a canopy cover of 10%-30% (light intensity 72.19%). There is a positive correlation between light intensity and the growth of jernang rattan under mixed stands, that is, the higher the light intensity, the better the growth of jernang rattan.

Pine resin is a highly valuable and sought-after non-timber forest product with multiple uses in many industrial sectors. Maritime pine (Pinus pinaster Ait.) is the main tapped species in Europe, where resin tapping activities are concentrated in only a few specific Mediterranean regions. Although maritime pine also occupies vast extensions under Atlantic climates, the resin tapping potential of these forests remains unexplored. The objectives of this study were to determine the main factors driving resin yield under Atlantic conditions and to adapt extraction practices to these regions. Resin yield was assessed in two naturally regenerated maritime pine forests in NW Spain. The effects of tree age, inter-tree competition, dendrometry, seasonality and wounding time on resin production were tested. The feasibility of a simple and rapid microtapping procedure to predict resin yield was also assessed. Tree age was identified as the main factor driving resin production, which increased considerably with tree age. Tree slenderness, tree size and inter-tree competition also significantly influenced resin production, although the effects were lower and likely mediated by age variation. Resin yield followed marked seasonal patterns, with maximum production in late summer and minimum production in winter. Resin flow decreased rapidly with time after wounding. More than 95 % of resin yield flowed in the first week after trees were wounded. The proposed microtapping procedure, which estimates resin flow from small wounds in just a few days, was shown to be a useful and reliable tool both for phenotyping and to predict resin yield in new stands. The results confirm the high potential for resin tapping in Atlantic maritime pine forests, although tapping should be restricted to stands older than 30 years and a season should be delimited for this activity in the region studied. Additionally, the periodicity of grooves (typically fortnightly) may need to be increased.

Pine trees produce large amounts of oleoresin to defend against biotic threats. Resin is highly costly to produce and investment in its production must be accurately optimized in relation to allocation to other life functions such growth. As a result of these costs, resin production is highly variable both genetically (among and within species) and plastically (across temporal and spatial environmental heterogeneity). The relative contribution of these sources of variation is, however, far from being completely understood. Besides being a main defensive mechanism, pine resin is also a valuable non-timber forest product that is regaining attention as a renewable resource for different industrial sectors. Improving our knowledge on the main drivers of resin production is vital to fine-tune resin-tapping management, especially in regions with little tradition in resin-tapping such are the Atlantic areas of the Iberian Peninsula. Here, we assessed resin flow and growth in a network of seven Maritime pine (Pinus pinaster) provenance tests established in North West Spain to explore the within species variation in resin flow, the plasticity of resin flow across sites and across the season and the (phenotypic and genotypic) relationships between resin flow and tree growth. Resin flow was assessed in three contrasting Maritime pine populations at three times within the season using a micro-tapping procedure that predicts well the resin yield potential for exploitation purposes. Results supported the theoretical predictions as resin flow significantly varied among populations, with populations from more favorable environmental conditions producing less resin than those from harsher conditions. Resin flow was positively correlated with tree size at the phenotypic level. However, the genetically-based relationship between growth potential and resin flow was markedly negative. Fast growing populations produced less resin than slow growing origins. Resin flow was also highly plastic across sites and across seasons, with resin flow consistently increasing towards the end of the growing season. Temperature and water deficit immediately before sampling emerged as main drivers of the observed variation in resin flow across sites and seasons. Results are valuable to understand the extremely large variation in defensive investment on resin-based defenses in conifer species, to model the potential of Atlantic Maritime pine forest for resin tapping, and to fine-tune the resin-tapping management of these forests.

Non-timber forest product commodities in Gunung Silanu Village are cashew, turmeric, candlenut, coffee, cocoa, ginger, and galangal. Among these commodities, cashew and turmeric are the most developed commodities. However, this study is focused on the cashew (Anacardium occidantale). Cashew seed processing in Gunung Silanu Village only reaches into the drying stage, even though there was a peeling tool available. This condition makes farmers market their cashew seeds directly. There is a problem that frequently encountered in marketing cashew seeds, namely the unconstant price of cashew seeds. This certainly affects farmers' income. Therefore, a study related to marketing channels for cashew nuts in the village of Gunung Silanu to see the price level at each marketing institution is needed. The purposes of this study were to determine marketing channels, analyze marketing margins, and marketing efficiency levels of cashew nuts (Anacardium occidentale) was a non-timber forest product at community forestry in Gunung Silanu Village. The results showed that there were two marketing channels. The first marketing channels were from farmers to large traders in the village of Gunung Silanu then to large traders in Jeneponto Regency. The second marketing channels were from farmers to small traders and large traders in Gunung Silanu Village then to large traders in Jeneponto Regency. The marketing margin of the big traders in the first channel is 15.6% with an efficiency level of 0.48%, while in the second channel is 13.4% and 11.3% for small traders and big traders respectively, so the total marketing margin is 23.3 % with an efficiency level of 0.48%. The most efficient channel is a channel with small costs, large margins, and a short marketing channel which is the first channel.

Quantifying the economic impacts of invasive species is an essential step in developing and prioritizing invasive species management. In particular, kudzu, Pueraria montana (Lour.) Merr. is an aggressive and non-native vine that not only causes ecological damage and reduces biodiversity, but can have multiple economic consequences such as loss of timber value and volume. Using current infestation locations in Oklahoma, southcentral USA, a Monte Carlo simulation was run to estimate the natural as well as anthropogenic spread rate of kudzu in the next five years. Simulations were supplemented with an economic impact analysis within the Impact Analysis for PLANing (IMPLAN) platform. To account for economic loss in the forest product industry, a replacement cost approach with a sensitivity analysis was conducted. Occurrence data collections revealed that current kudzu populations are already established in Oklahoma forests. The results demonstrate that by year five, total industry output could be reduced by $167.9 million, which will influence 780 jobs in the most extreme case scenario. The predicted economic loss due to kudzu expansion could act as an incentive for appropriate management practices and plans to be implemented.

The Himalayan giant nettle (Girardinia diversifolia), commonly called Allo in Nepali has been a major source of income in many parts of the Himalayan region. It is a fiber yielding non-timber forest product (NTFP) which belongs to the botanical family Urticaceae. It has been harvested for many years in the Himalayan region for cultural, medicinal and economic purposes. The fiber has high economic value as it is considered superior to jute. Different parts of the plant such as roots, stems, leaves, and inflorescences are used to prepare traditional medicinal formulations to treat various diseases and ailments for the local people.

Vultures play an essential role in environmental health by scavenging meat from carcasses and take place end of the ecosystem as decomposer, without which the ecosystem is incomplete. The vultures are under serious threat in all its distribution ranges. In Southern India, there are five species of vultures successfully thriving unlike Northern Indian population. Still, there are many conservation threats such as livestock grazing, bamboo cutting, non-timber forest product collection, honey collection, pilgrims threat, and deliberate poisoning threatening the securement of the population. This paper discusses the conservation threats and its impacts in the southernmost wild viable vulture population.

Fruits of Ximenia americana have socio-economic value for the local people in West Africa. Understanding the possible influence of climate conditions on fruit production is a basis for better exploitation planning and sustainable management of the species. This study aims to assess the fruit production of X. americana according to tree size across a climatic gradient. The mean total number of fruits, the mean weight of fruits and the total weight of fruits per tree were calculated based on a sample of 450 trees distributed in five stem diameter classes and three climatic zones. Stem diameter, total height and crown volume were measured for each sampled tree. The global fruit production ranged from 200.37 ± 32.65 to 1027.20 ± 267.72 fruits/tree according to tree size. Trees with larger crown volume produced more fruits with higher total weight than those with smaller crown. The climatic zone significantly affected fruit production (p < 0.0001). The highest fruit weight per tree was recorded in the south-Sudanian phytogeographic zone, with a mean value of 1.49 ± 0.26 kg while the lowest value was observed in the sub-Sahel zone, with 0.67 ± 0.11 kg. The best prediction models of X. americana fruit production included crown volume and climatic zone.
