متن کاملSoil Microbial Communities in Natural and Managed Cloud Montane Forests
Forest management often results in changes in soil microbial communities. To understand how forest management can change microbial communities, we studied soil microbial abundance and community structure in a natural Chamaecyparis (NCP) forest, a disturbed Chamaecyparis (DCP) forest, a secondary (regenerated) Chamaecyparis (SCP) forest and a secondary (reforested) Cryptomeria (SCD) forest. We a...
متن کاملInvestigation some of the Biotic and Abiotic Variables Effective on the Diameter Increment of the Beech Trees at Fixed Sample Plots level by Growth Models

This study examines the effects of biotic and abiotic factors on the diameter increment of oriental beech (Fagus orientalis Lipsky) in a high-elevation forest in northern Iran using permanent sample plots. The aim of this study was identification and quantifying environmental factors such...

How Timber Harvesting and Biodiversity are Managed in Uneven-Aged Forests: A Cluster-Sample Econometric Approach
Nonindustrial private forest (NIPF) landowners have been shown to be more multi-objective by nature than industrial landowners: they give more importance to standing timber and forestland for the amenity values they provide (Newman & Wear, 1993). Among analyses of forest landowner behaviour, the household production framework recognises the benefits associated with forest amenities, as first ap...
