Natural Forest Management and Conservation of Biodiversity in Tropical Forests
As a reaction to the continued dwindling of tropical forest resources, many research and development organizations have turned to the idea of natural forest management in the hope of making tropical forest lands more profitable while maintaining biodiversity. Assertions of sustainability in logging practices have been inadequately supported, however. We begin with a review of the present knowle...

متن کاملAir pollution, precipitation chemistry and forest health in the Retezat Mountains, Southern Carpathians, Romania.
In the Retezat Mountains concentrations of O3, NO2 and SO2 in summer season 2000-2002 were low and below toxicity levels for forest trees. While NH3 concentrations were low in 2000, the 2001 and 2002 concentrations were elevated indicating possibility for increased N deposition to forest stands. More than 90% of the rain events were acidic with pH values <5.5, contributing to increased acidity ...
