The Ministry of Environment is competent to adopt measures to ensure the protection of wild flora species, and to take the necessespaary measures to protect endangered or endangered species. Within this framework, it must intervene in the management, exploitation, transport and commercialization of species and individuals of wild flora and their primary products, whether public or private property. As a control and surveillance measure, the natural resources code requires that all primary forest products entering, leaving or moving within the national territory must be covered by a permit. For the mobilization of forest products, authorization documents are required, and these will vary depending on the forest products, which according to the legislation are classified as: 1) single online safe-conduct, 2) mobilization certificate and 3) mobilization remission.

The present study aimed to evaluate the physical, chemical and anatomical properties of Cryptomeria japonica wood. For that, trees with 13 years old, from an experimental planting, were sampled. The wood was classified as low density (0.314 g cm-3), with low values of longitudinal contractions (0.31%), radial (2.09%), tangential (5.48%) and volumetric (7.57%), but high anisotropy coefficient (2.62), indicating the susceptibility of this species to drying defects. Regarding the chemical composition, it presented low levels of extractives (2.14%) and ashes (0.32%), but high content of lignin (31.36%). The tracheids have 2.18 mm length; width of 25.06 µm; lúmen diameter of 15.89 µm and wall thickness of 4.59 µm, with interesting indicators for papermaking, and presenting good quality due to the Runkel index (0.61) and felting (87.78) and medium quality for flexibility coefficient (61.23%) and wall fraction (36.94%). The characteristics of C. japonica wood indicate potential to be used as alternative to supply the demand of the industrial sector for raw material, especially in the South of Brazil.

The study includes the analysis of cultural, commercial, and safety factors that affect the potential of the trade of the red sour pitaya (Stenocereus gummosus), as well as its characterization, consumer patterns, consumption channels, and the relevance, identity, and cultural value of the fruit in the Municipality of La Paz, Baja California Sur, Mexico. The investigation has the objective of understanding the perception of the product in local knowledge, which is identified in the study area, where the wild fruit takes an added value in informal commercialization and is amalgamated with the local culture. For the analysis and data collection, a simple random sampling was conducted, on 227 economically active people with purchasing power. The method of applying the instrument was digital, limiting face-to-face contact with people due to the current Covid 19 pandemic. The exercise characterizes a population with mostly university studies, which consumes the product in a traditional way, which reflected a greater appreciation of the pitaya fruit, by older people.

Wooden housing is one of the most sustainable building alternatives. In many European and North American countries, wooden houses provide the most common, economical, and practical solution for construction. The timber buildings present adequate levels of durability, acoustics, and thermal comforts. Despite their popularity, wood houses do not have a standardized classification to define and organize their main aspects. In literature dealing with timber construction, most authors emphasize structural systems for large spans (bridges, hangars, roofs, etc.). The presence of some classifications of timber construction results in unclear issues, and few studies have covered and regarded wooden buildings as residential construction typologies. Accordingly, this paper proposes a classification that connects the aspects and details of wooden housing materials in relation to the industrialization level and chronological origin. We expect this classification to assist in a better understanding of distinct wooden housing techniques commercially produced worldwide, diffusing their concepts and possibilities as forestry-timber products.

Forests play an important role in the community’s livelihood, and this role has created an important relationship or mutual dependence between the forest and the community. Therefore, this study was conducted to identify the types of community’s forest dependency and to identify the effects of community’s forest dependency towards forest resources and wildlife abundance. The data were collected using the self-administered questionnaire, involving 204 community members in Bau District, Sarawak. The results show that the common types of forest dependency are private land ownership, land area of less than 10 acres, less than 50 meters of house distance to forest, land utilization for house site and agriculture purposes, and estimated income and expenditure of less than RM 1000. The land use–paddy field, forest resources–handicraft and forest resources–water source significantly predict the abundance of forest cover. The land use–house site, house distance to forest and forest resources–hunting significantly predict the wildlife abundance. The forest resources–house material and forest resources–water source significantly predict the water source quality. The community’s forest dependency needs to be revisited to further understand the community’s needs and how this dependency can be made more sustainable, while less destructing the forest. Hence, a sustainable framework involving all stakeholders is needed to manage the community’s forest dependency. [ABSTRACT FROM PUBLISHER]

Based on the features of the forest products trading information, a compound keywords vector space model was utilized to represent the user interest model of the forest products trading information website. Every compound keyword in the vector space consists of three keywords, which are supply and demand classification, the name of the forest product and the production place, and some information about the specifications, price and the company name of the forest products. Every compound keyword has a user interest value. The learning and updating of the user interest model were reaiized through the browsing, registering and releasing behaviors of the users and introducing the forgetting factors for the interest values, respectively. The perssstent interests and the temporary interests of the users were distinguished by introducing a temporary interests group. Finally, the recommendation algorithms based on the contents itering were proposed based on our user interest model, and its advantage was demonstrated by comparison experiments [ABSTRACT FROM AUTHOR]
