Biodiversity and structure of subtropical Boliviano‐Tucumano mountain forests,depending on disturbance intensity due to forest grazing and selective timber logging

摘要：

The Parque N atural de Flora y Fauna Tariquía, Department of Tarija, Bolivia is dominated by the Boliv iano‐ Tucumano subandean semideciduous and seasonal evergreen vegetation (Navarro,2004).Theses forests have been used as dry season grazing area of Criollo cattle for centuries.In the last decades, easier accessible parts of the reserve were additionally affected by selective timber logging.The influence of forest grazing and selective timber logging on the plant species composition of the Boliviano‐Tucumano mountain forests has not been studied before.This study investigated plant species diversity and forest structure in areas with different disturbance regime.The results can serve as a basis for decisions regarding the future management of the reserve.
