Biodiversity differences between managed and unmanaged forests: meta-analysis of species richness in Europe.
Past and present pressures on forest resources have led to a drastic decrease in the surface area of unmanaged forests in Europe. Changes in forest structure, composition, and dynamics inevitably lead to changes in the biodiversity of forest-dwelling species. The possible biodiversity gains and losses due to forest management (i.e., anthropogenic pressures related to direct forest resource use)...
متن کاملBIODIVERSITY OF WOODY SPECIES IN Acer platanoides SITES IN THE SHAFAROUD FORESTS, GILAN (IRAN)
In this research, biodiversity was investigated in the species diversity level. The objective of this research was to study of Norway Maple (Acer platanoides L.) dispersion and biodiversity of associated woody species in the Shafaroud forests, Gilan (IRAN). In this regard, a 0.5 ha lozenge sample plot was selected with considering presence of Norway Maple in each site. In each plot, geographic ...
متن کاملThe Diversity of Woody Species in the Ecosystems of Sweet Chestnut, Hazel, (Corylus avellana L.) and Italian Cypress Trees in Guilan Forests, Iran
The purpose of this study is to determine the woody species diversity in Sweet chestnut tree, Hazel-tree and Italian cypress ecosystems in the Guilan forests. A lozeng 0.5 ha sample plot was selectively established on each site. In the Sweet chestnut ecosystems , 4 sites were classified, whereas 10 sites of Hazel tree and Italian cypress ecosystems were classified based on species composition. ...
متن کاملDifferences in Genetic Structure among Fagus orientalis Lipsky (Oriental Beech) Populations under Different Management Conditions: Implications for in situ Gene Conservation
Resource sustainability requires a thorough understanding of the influence of forest management programs on the conservation of genetic diversity in tree populations. To observe how differences in forest management affect the genetic structure of Fagus orientalis Lipsky (oriental beech), we evaluated thirteen beech sites across Hyrcanian forests, based on six microsatellite loci. Significant di...
متن کاملAccumulation and Connectivity of Coarse Woody Debris in Partial Harvest and Unmanaged Relict Forests
When a tree dies, it continues to play an important ecological role within forests. Coarse woody debris (CWD), including standing deadwood (SDW) and downed deadwood (DDW), is an important functional component of forest ecosystems, particularly for many dispersal-limited saproxylic taxa and for metapopulation dynamics across landscapes. Processes, such as natural disturbance or management, modif...
