Histosols cover about 8–10% of Lithuania's territory and most of this area is covered with nutrient-rich organic soils (Terric Histosols). Greenhouse gas (GHG) emissions from drained Histosols contribute more than 25% of emissions from the Land Use, Land Use Change and Forestry (LULUCF) sector. In this study, as the first step of examining the carbon dioxide (CO
2 ) fluxes in these soils, total soil CO2 efflux and several environmental parameters (temperature of air and topsoil, soil chemical composition, soil moisture, and water table level) were measured in drained Terric Histosols under three native forest stands and perennial grasslands in the growing seasons of 2020 and 2021. The drained nutrient-rich organic soils differed in terms of concentrations of soil organic carbon and total nitrogen, as well as soil organic carbon and total nitrogen ratio. The highest rate of total soil CO2 efflux was found in the summer months. Overall, the rate was statistically significant and strongly correlated only with soil and air temperature. A trend emerged that total soil CO2 efflux was 30% higher in perennial grassland than in forested land. Additional work is still needed to estimate the net CO2 balance of these soils.

http://blogs.biomedcentral.com/on-physicalsciences/2021/04/15/forest-bioenergy-sustainable/ Forest biomass harvesting guidelines help ensure the ecological sustainability of forest residue harvesting for bioenergy and bioproducts, and hence contribute to social license for a growing bioeconomy. Guidelines, typically voluntary, provide a means to achieve outcomes often required by legislation, and must address needs related to local or regional context, jurisdictional compatibility with regulations, issues of temporal and spatial scale, and incorporation of appropriate scientific information. Given this complexity, comprehensive reviews of existing guidelines can aid in development of new guidelines or revision of existing ones. We reviewed 32 guidelines covering 43 jurisdictions in the USA, Canada, Europe and East Asia to expand upon information evaluated and recommendations provided in previous guideline reviews, and compiled a searchable spreadsheet of direct quotations from documents as a foundation for our review. Guidelines were considered in the context of sustainable forest management (SFM), focusing on guideline scope and objectives, environmental sustainability concerns (soils, site productivity, biodiversity, water and carbon) and social concerns (visual aesthetics, recreation, and preservation of cultural, historical and archaeological sites). We discuss the role of guidelines within the context of other governance mechanisms such as SFM policies, trade regulations and non-state market-driven (NSMD) standards, including certification systems. The review provides a comprehensive resource for those developing guidelines, or defining sustainability standards for market access or compliance with public regulations, and/or concerned about the sustainability of forest biomass harvesting. We recommend that those developing or updating guidelines consider (i) the importance of well-defined and understood terminology, consistent where possible with guidelines in other jurisdictions or regions; (ii) guidance based on locally relevant research, and periodically updated to incorporate current knowledge and operational experience; (iii) use of indicators of sensitive soils, sites, and stands which are relevant to ecological processes and can be applied operationally; and (iv) incorporation of climate impacts, long-term soil carbon storage, and general carbon balance considerations when defining sustainable forest biomass availability. Successful implementation of guidelines depends both on the relevance of the information and on the process used to develop and communicate it; hence, appropriate stakeholders should be involved early in guideline development.

Soil organic carbon (SOC) stocks at national level were estimated to provide more accurate estimates on SOC for the Lithuanian GHG inventory. The SOC stocks in the forest floor, grassland litter, and in mineral or organic topsoil (0–30 cm) of forest land, grasslands, and croplands were estimated. The assessment was based on forest floor and peat topsoil mass, mineral topsoil bulk density, and carbon concentration in 754 permanent observation plots on 9 × 9 km grid of the National Forest Inventory in Lithuania. The SOC stocks were obtained for eight WRB Reference Soil Groups to provide the estimates for land use, land‐use change, and forestry reporting. The SOC stocks in the forest floor, topsoil of mineral, and peat layers were identified for soils under different land uses. The mean SOC concentrations in the 0–10 and 10–30 cm topsoil of most soil groups, especially fertile forest soils (Cambisols, Luvisols +Retisols) were higher for forest land and grasslands, and lower for croplands. The total averaged SOC stock in the forest floor in mineral and organic soils was 6.97 t ha−1, whereas in the litter of grasslands it was 0.54 t ha−1. The averaged SOC stock in topsoil varied from 56 t ha−1 (Arenosols) to 118 t ha−1 (Cambisols) in mineral forest soils and was 150 t ha−1 (Histosols) in organic forest soils. The total averaged SOC stock in mineral topsoil of forest land, grassland, and cropland was 80, 74, and 72 t ha−1, respectively. [ABSTRACT FROM AUTHOR]

- Abstract
The European beaver Castor fiber is well-known as an ecosystem engineer that greatly affects landscape structure, biodiversity as well as physical and chemical properties of surface water bodies. Beaver ponds alter surface water bodies by raising water elevation, decreasing flow velocity and altering the morphology of streams or drainage ditches, which can reduce the concentrations of organic carbon (OC) and nutrients (N, P). Recent studies indicated that mercury transforms into hazardous and neurotoxic methylmercury (MeHg) in beaver impoundments by biological processes in anaerobic conditions. However, the knowledge about nutrients and MeHg levels in impounded forest waterbodies is scarce in Lithuania. We aimed to ascertain the alteration in concentrations and stocks of OC, nutrients and MeHg in water and sediments from upstream and downstream, as well as within beaver dams and ponds during the growing seasons of 2016--2018. Results showed higher concentrations of dissolved organic carbon (DOC) and nutrients (P and N) in upstream water samples compared to those of downstream from beaver dams. Meanwhile, in sediments mean stocks of OC, P and N were the highest in the middle part of the ponds and in beaver dams. Moreover, the concentrations and stocks of MeHg in sediments were higher in beaver dams than in any other parts of beaver impoundments (upstream, mid-pond, pond periphery and downstream). We conclude that dam bottom sediments were rich in OC, N and P, and at the same time, contained toxic MeHg. Therefore, beaver dams could act as a trickle filter by improving water quality, in our case, DOC, N and P leaching, from riparian forests and soils, but may also act as hotspots of mercury methylation.

- Abstract
An altered microclimate after harvesting may affect the soil nutrient content. There is a growing concern about clear cuttings. Shelterwood cuttings are an alternative practice to clear-cutting. Compared with clear-cutting, shelterwood cuttings cause fewer changes in the soil microclimate and in the physical, chemical and biological soil properties. Shelterwood harvesting may mitigate the impact of harvesting on the ecosystem's functioning. The aim of the study was to evaluate the effect of shelterwood and clear-cuttings on forest soil chemical properties relative to uncut sites, and to determine their changes after shelterwood cutting in pine-dominated stands on sandy soils of the European hemiboreal zone, in Lithuania. Nitrate and ammonium nitrogen in mineral soil was estimated in shelterwood, clear cuttings and in a mature stand. Changes in organic carbon, total nitrogen, nitrate and ammonium nitrogen, available phosphorus and potassium in mineral soil were estimated in 1-, 3-, 5- and 7-year-old shelterwood cuttings as well. Organic carbon in the soil's mineral layer in 1- to 7-year-old cuttings sites was higher than in uncut stands. Both organic carbon and total nitrogen were slightly higher in 1- to 5-year-old cuttings. Nitrate nitrogen was higher after tree cutting. The highest mineral nitrogen concentration was in clear cuttings. Changes in the concentration of available phosphorus were similar as in mineral nitrogen. The concentration of available potassium was higher only one year after cutting compared to the untouched stands. Results confirm that shelterwood cuttings had a weaker negative effect on soil nutrients, especially on mineral nitrogen, compared to clear cuttings. The effect of shelterwood cuttings on soil nutrient was short-lived and lasted up to 5 years. [ABSTRACT FROM AUTHOR]

This article discusses the recent changes in agricultural land-use and soil re-naturalization processes in Lithuania. The paper briefly presents re-naturalization research currently carried out in Lithuania and analysis of recent changes in arable land. Although re-naturalization research in Lithuania is relatively young, but area of agrarian soils in Lithuania affected by re-naturalization processes is huge (about 1 million ha according to year 2005 estimates). According to statistical land-use data and land-use surveys, area of arable land decreases every year, and the annual change ranges from ~1% (in 1990-1991) to 10% (in 2005). Certain cycles of changes are obvious: from 1990 to 1995 the decline in arable lands was faster. There was noticeable slowdown in the period up to 2002, followed by sudden acceleration reaching its peak in 2005. During the last five years the situation has stabilized with arable land decreasing annually by 3-4%. It is believed that in different parts of Lithuania re-naturalization processes currently progress quite rapidly and this trend will continue in future. Some scientists predict that with development of unconventional or even non-agrarian farming the agrarian landscape that dominated for centuries should be gradually replaced by forested landscape.

Article discusses the recent changes in agricultural land-use and soil re-naturalization processes in Lithuania. The paper briefly presents re-naturalization research currently carried out in Lithuania and analysis of recent changes in arable land. Although re-naturalization research in Lithuania is relatively young, but area of agrarian soils in Lithuania affected by re-naturalization processes is huge (about 1 million ha according to year 2005 estimates). According to statistical land-use data and land-use surveys, area of arable land decreases every year, and the annual change ranges from – 1% (in 1990-1991) to 10% (in 2005). Certain cycles of changes are obvious: from 1990 to 1995 the decline in arable lands was faster.

It is believed that in different parts of Lithuania re-naturalization processes currently progress quite rapidly and this trend will continue in future. Some scientists predict that with development of unconventional or even non-agrarian farming the agrarian landscape that dominated for centuries should be gradually replaced by forested landscape. Obviously, for the optimization of agrarian land use and planning of changes in it permanent long-term research is needed, from registration of annual changes to long-term monitoring of soil status. Thus the linking of causes and effects of re-naturalization processes with extent of actual changes in agricultural land and the summarized knowledge of various fields of science are preconditions for costefficient and naturally optimized soil re-naturalization regulation. Pedological soil re-naturalization research mainly focused on southern and south-eastern Lithuania characterised by low productivity and diverse soil cover. Studies carried out deal with a variety of potential transformations of arable land use, including grassland, afforestation, or even effects of long-term fallowing on pedological properties, soil properties change and nutrient circulation and energy, moreover, these studies also deal with bio-diversity issues. Studies at the Institute of Agriculture and Forestry have revealed that soil re-naturalization significantly changes chemical and microbiological parameters of soil. The analyzed parameters include soil pH, P and K mobile, organic carbon, totai nitrogen and soil microbial properties. However, studies based on totai or mobile mineral nutrients analysis, and soil organic carbon status remain largely uncovered. Complex field and laboratory studies on soil organic carbon (DOA) and nutrient content of organic and mineral forms (oNPS) by using different methods of soil re-naturalization and soil carbon change prediction modelling have recently been started at the Vokė Branch of LRCAF. Previously such studies in Lithuania were only occasional, therefore now they will make an important contribution to devising scientifically based, rational and optimized land use strategy. [...]

Straipsnyje aptariami tyrimai yra svarbūs saugomų teritorijų atžvilgiu ir gali turėti praktinę reikšmę koreguojant mažiau palankių ūkininkauti vietovių žemėnaudos transformacijos strategiją. Šiuo metu gausu įvairių rekomendacijų, kaip reikėtų ūkininkauti nederlingos žemės vietovėse. Jau daugiau kaip prieš dešimtmetį Lietuvoje atkreiptas dėmesys, kad kaimo turizmo plėtra sudaro prielaidas žemės ūkio naudmenų transformacijai, o tai ypač aktualu nederlingose žemėse, taip pat ir saugomose teritorijose. Dažniausiai nederlingas žemes siūloma apsodinti mišku. Tačiau negalima vienareikšmiai propaguoti naujų miškų įveisimo, saugomose teritorijose tikslinga išsaugoti ir Lietuvos tradiciniam kraštovaizdžiui būdingus bei biologinės įvairovės išsaugojimui būtinus žolynus. Tokia žemėnauda taip pat leistų sukaupti pakankamai didelį kiekį biomasės bei biogeninių elementų sankaupų joje ir racionaliai panaudoti per dirbamos žemės naudojimo laikotarpį dirvožemio armenyje sukauptas gausias kai kurių maisto medžiagų atsargas. Didesnis dėmesys galėtų būti skiriamas dekoratyvesnėms žolynų rūšims, taip pat ir medingiems augalams. This article discusses the important research in terms of protected areas and may have practical value in less-favored agricultural areas and land use transformation strategy adjustment. 43% of national and regional parks in Lithuania are established in low fertile areas, at the present, numerous recommendations available how to farm on infertile areas. Already for more than a decade ago, attention was paid for rural tourism development, which is especially important for infertile lands, including protected areas. The most infertile land planting of a forest most often proposed. However, it can not be promoted only for new afforestation in protected areas, it is appropriate to preserve Lithuanian traditional and typical landscape and biodiversity conservation requires the grassland areas. Such land use would also accumulate significant quantities of biomass and biogenic elements in it, and important for rational use during agricultural period in the arable layer of soil accumulated large concentrations of nutrients. Greater attention should be paid to decorative grass species, including honey plants. Suggested priorities for rural tourism development in Neris Regional Park are water and nature-cognitive tourism, in Aukstadvaris Regional Park – water and passive tourism.

Lapijos nuokritos rinktos Dubravos EMM urėdijoje prie Kauno marių buvusiose žemės ūkio naudmenose gretimai augančiuose 41 metų amžiaus skirtingos rūšinės sudėties (Fraxinus excelsior L., Betula pendula Roth., Tilia cordata Mill. ir Quercus robur L.) lapuočių želdiniuose. Lapijos nuokritų masė, nustatyta dviem skirtingais surinkimo metodais (nuokritų rinktuvais ir nuo mineralinio dirvožemio paviršiaus), iš esmės skyrėsi tik liepos želdiniuose. Daugiausia lapų nuokritų susikaupė ąžuolo ir liepos želdiniuose. Apskaičiavus maisto medžiagų sankaupą lapijos nuokritose paaiškėjo, kad skirtingos rūšinės sudėties želdiniuose azoto (N) ir kalio (K) kiekiai labiausiai priklausė nuo nuokritų masės. Fosforo (P), magnio (Mg), kalcio (Ca) ir, ypač, sieros (S) sankaupos tirtuose miško želdiniuose daugiausia skyrėsi dėl nevienodų šių elementų koncentracijų lapų nuokritose. Duomenų analizė parodė, kad su lapų nuokritomis miško paklotėje daugiausia maisto medžiagų susikaupia liepos ir ąžuolo želdiniuose. Leaf litterfall was collected in Dubrava Experimental and Training Forest Enterprise in adjacent 41-year-old forest plantations with four different species (Fraxinus excelsior L., Betula pendula Roth., Tilia cordata Mill., and Quercus robur L.) planted in Central Lithuania on “Kauno marios” sea-shore on former agricultural land. Two different methods of forest litterfall collection (litterfall traps and litterfall collection from the denuded up to mineral soil ground quadrates) gave similar values of leaf litterfall mass in all stands with exception of lime leaf litterfall in the lime plantation. The highest amounts of leaf litterfall were collected in oak and lime plantations. Differences between species in fluxes of nitrogen (N) and potassium (K) with leaf litterfall were very similar to inter-specific differences in leaf litterfall amount between species. For phosphorus (P), magnesium (Mg), calcium (Ca), and especially for sulfur (S), no such similarity was observed due to considerable differences in concentrations of these elements between some species. Comparative analysis had showed that the total annual return of the nutrients through the litterfall was the highest in lime and oak plantations. Исследования проводились в Дубравском эксперементально – учебном лесхозе в oднoвозрастных (возраст – 41 гoд) лесных культурах различных лиственных пород (Fraxinus excelsior L., Betula pendula Roth., Tilia cordata Mill. и Quercus robur L.), которые были заложены возле Каунасского моря на бывших сельхозугодиях. Масса опада листьев, собранная двумя различными методами (коллекторами и с поверхности минеральной почвы), достоверно различалась лишь в лесных культурах липы. При этом наибольшая масса опада листьев установлена в лесных культурах дуба и липы. Накопление азота (N) и калия (К) в опаде листьев было выше в лесных культурах пород с бόльшей массой листового опада. Межвидовые различия в накоплении фосфора (Р), магния (Мg), кальция (Са) и в особенности серы (S) были в значительной степени обусловлены разницей в концентрациях этих элементов в опавших листьях разных пород. В целом, приток питательных веществ с опавшими листьями в лесную подстилку был наиболее высоким в культурах липы и дуба.

Lietuvos žemdirbystės instituto Perlojos bandymų stotyje 1960 m. įrengtas stacionarinis bandymas, siekiant palyginti žemės ūkio augalų ir pušynų produktyvumą smėlžemiuose. Nuo 1995 m. bandyme ariamos žemės dirvonuoja. Straipsnyje pateikiami 2004 m. atliktų tyrimų duomenys apie įveistų ir savaime atžėlusių pušynų būklę ir augimą bei palyginamos smėlžemių cheminės savybės ir mikroflora pušies želdiniuose ir dirvonuojančiose žemėse. Nustatyta, kad savaiminių pušies žėlinių būklė yra geresnė negu tankesnių želdinių, kurie yra pažeisti šakninės pinties (Heterobasidion annosum (Fr.) Bref.). Tačiau retesni savaiminiai žėliniai yra mažiau produktyvūs, juose žymiai blogesnė medžių stiebų kokybė. Smėlžemių tyrimams surinkti miško paklotės (OL ir OFH sluoksniai) ir ariamojo Ap horizonto viršutinio 0-2 cm ir 2-10 cm storio sluoksnių ėminiai. Nustatyta, kad palyginti su pušies želdiniais 10 metų dirvonuojančios žemės yra 1,2-1,9 pHCaCl2 mažiau rūgščios ir 2-3 kartus labiau pasotintos judriaisiais P2O5 ir K2O. Taciau pušies želdiniuose, kadangi po miško paklote formuojasi humusinis Ah horizontas, yra didesnės mineralinio azoto (NO3-N + NH4-N) ir organinės anglies koncentracijos. Apskaičiuota, kad pušies želdiniuose miško paklotėje ir viršutiniame 10 cm storio mineraliniame smėlžemių sluoksnyje Nmin. sankaupa (2,67±0,38 g N m-2) yra didesnė 3 kartus, o Corg.

The soil of the experiment has not been cultivated since 1995. In 2004 the experiment was re-established in order to assess the growth and the condition of planted and naturally regenerated Scots pine stands, and evaluate the impact of afforestation on the chemical and biological properties of the soils. The conditions of naturally regenerated pine stands are significantly better because denser pine plantations are damaged by Heterobasidion annosum (Fr.) Bref. However the productivity and the quality of tree stems are higher or better in survived pine plantations. For investigation of Arenosols properties, the organic O-horizon (OL and OFH layers) and mineral topsoil (0-2 cm and 2-10 cm) of pludged Ap-horizon were sampled. It was detected that despite 10-years non-cultivation period the abandoned farmland is still less acid (by 1.2-1.9 pHCaCl2), and 2-3 times more saturated with mobile P2O5 and K2O compounds. Though, the concentrations of mineral nitrogen (NO3-N + NH4-N) and organic carbon in topsoil are higher in pine plantations. This is because below organic O-horizon the Ah-horizon is under the development. To compare with non-cultivated at present farmland in pine plantations the mineral nitrogen and organic carbon pools are... [to full text]

Decomposition intensity of leaf litters of native tree species, England oak (Quercus robur L.) and Norway maple (Acer platanoides L.), and invasive tree species, northern red oak (Q. rubra L.), sycamore maple (A. pseudoplatanus L.) and box elder (A. negundo L.), were studied in field conditions on the surface of mineral topsoil of Luvisol. It was determined that the decomposability leaf litter of native tree species was faster than alien ones. Among all studied tree species the decrease of total carbon (C) and total nitrogen (N) and, consequently, the decrease in C:N ratio through the time were the highest in leaf litter of A. negundo. It shows, that leaf litter fall of this alien maple could creates more beneficial nutrient and illumination conditions for soil ground vegetation to compare with native maple A. platanoides. Meanwhile the difference in such effects among leaf litters of Q. robur and Q. rubra was eliminated by the diversities in the mass, the decomposability and the contents of C and N.

The aim of the study was to investigate the influence of low severity surface fires on the ground vegetation, soil chemical changes and soil microbiota in Scots pine stands on sandy soils (Arenosols). The study was conducted in the eastern part of Lithuania (55° 35'N, 26° 07'E). The annual investigations in 1–4-year-old burned sites showed that low severity surface fires mostly affected the above-ground part of the ground vegetation. The influence of surface fire on soil chemical properties and soil microbiota was minor. Only slight increases in pH and in the content of total N in soil organic layer were detected. Concentrations of mobile K
2 O and heavy metals (Cd, Cr, Cu, Mn, Zn and Fe) slightly increased in the mineral topsoil.

15 páginas.- 6 figuras.- 93 referencias, Fungi are highly diverse organisms, which provide multiple ecosystem services. However, compared with charismatic animals and plants, the distribution patterns and conservation needs of fungi have been little explored. Here, we examined endemicity patterns, global change vulnerability and conservation priority areas for functional groups of soil fungi based on six global surveys using a high-resolution, long-read metabarcoding approach. We found that the endemicity of all fungi and most functional groups peaks in tropical habitats, including Amazonia, Yucatan, West-Central Africa, Sri Lanka, and New Caledonia, with a negligible island effect compared with plants and animals. We also found that fungi are predominantly vulnerable to drought, heat and land-cover change, particularly in dry tropical regions with high human population density. Fungal conservation areas of highest priority include herbaceous wetlands, tropical forests, and woodlands. We stress that more attention should be focused on the conservation of fungi, especially root symbiotic arbuscular mycorrhizal and ectomycorrhizal fungi in tropical regions as well as unicellular early-diverging groups and macrofungi in general. Given the low overlap between the endemicity of fungi and macroorganisms, but high conservation needs in both groups, detailed analyses on distribution and conservation requirements are warranted for other microorganisms and soil organisms., The bulk of the funding is derived from the Estonian Science Foundation (grants PRG632, PRG1170, PRG1615, MOBTP198), EEA Financial Mechanism Baltic Research Programme (EMP442), and Novo Nordisk Fonden (NNF20OC0059948).

Moksliniai tyrimai rodo, kad XXI a. paprastosios eglės (Picea abies (L.) H. Karst.) pažeidžiamumo rizika išaugs. Darbo tikslas – nustatyti paprastosios eglės (Picea abies (L.) H. Karst.) būklės ir pažeidžiamumo tendencijas Lietuvoje, įvertinti juos lemiančius veiksnius ir galimą klimato kaitos įtaką. Uždaviniai: nustatyti eglės lajų būklės kaitos dėsningumus 1990–2013 metais skirtinguose Lietuvos klimatiniuose rajonuose ir hidrotopuose bei įvertinti klimato veiksnių ir galimą klimato kaitos įtaką lajų defoliacijai; išaiškinti eglės biotinių ir abiotinių pažeidimų gausos pokyčių tendencijas, nustatyti lemiančius veiksnius bei įvertinti pažeidimų poveikį medžių būklei; nustatyti eglės liemens puvinio paplitimą lemiančius veiksnius ir puvinių įtaką lajų būklei; nustatyti savaiminio žėlimo eglių fenologinių formų struktūros pokytį skirtinguose Lietuvos klimatiniuose rajonuose. Darbo mokslinis naujumas. Pirmą kartą Lietuvoje atlikti sistemingi klimato pokyčių poveikio eglės būklei tyrimai. Išaiškinti svarbiausi klimato veiksniai lemiantys eglių lajų būklę bei įvertintas jų reikšmingumas skirtinguose Lietuvos klimatiniuose rajonuose ir augavietėse augančioms eglėms. Išaiškinti pagrindiniai biotiniai ir abiotiniai eglę pažeidžiantys veiksniai ir įvertinta jų įtaka lajų būklei. Įvertintas eglės liemens puvinio intensyvumo poveikis lajų defoliacijai. Nustatytas savaiminio žėlimo eglių fenologinių formų pasiskirstymas brandžiuose eglynuose ir žėliniuose Lietuvos klimato rajonuose. Research studies indicate that during the XXI century the rate of damages and vulnerability of Norway spruce (Picea abies (L.) H. Karst.) will increase. The aim of the study was to assess changes of condition and vulnerability of Norway spruce in Lithuania and evaluate the impact of the main affecting factors, including climate change. To achieve this aim the following objectives were set up: to evaluate dynamics of spruce crown condition during 1990–2013 period in the different climatic regions of Lithuania and hydrotops and assess the impact of climatic factors on defoliation; to identify factors wish have impact on frequency of biotic and abiotic damages, evaluate dynamics of damages and assess relation between damages and crown condition; to identify factors wish have impact on frequency of wood decay in spruce stands and assess the impact of wood decay on crown defoliation; to assess changes of the spruce phonological structure in different climatic regions of Lithuania. Novelty of the study. For the first time in Lithuania a systematic (integrated) research has been done one the Norway spruce condition in a changing climate. The effects of precipitation and temperature on crown condition in different climatic and site humidity gradients were identified. The key biotic and abiotic damaging factors were identified and was assessed they impact on crown defoliation. Relation of incidence of decay and crown defoliation was identified.
