Abstract

Reviews the effects of disturbances such as fire, grazing, soil disturbance, and nutrient addition on plant species diversity and invasion, with particular emphasis on grassland vegetation. Individual components of the disturbance regime can have marked effects on species diversity, but it is often modifications of the existing regime that have the largest influence. Similarly, disturbance can enhance invasion of natural communities, but frequently it is the interaction between different disturbances that has the largest effect, The natural disturbance regime is now unlikely to persist within conservation areas, since fragmentation and human intervention have usually modified physical and biotic conditions. Active management decisions must now be made on what disturbance regime is required, and this requires decisions on what species are to be encouraged or discouraged. -from Authors
