FOREST DEGRADATION

May be generally defined as a reduction in tree density and/or increased disturbance to the forest that results in the loss of forest products and forest-derived ecological services. The FAO defines degradation as changes within the forest class (for example, from closed to open forest) that negatively affect the stand or site and, in particular, lower production capacity. Common causes of forest degradation include selective felling, fuelwood collection, road building, and shifting cultivation.
