Abstract

Efforts to preserve biodiversity have been focused primarily on remaining areas of natural ecosystems, but only 5% of the terrestrial environment is unmanaged and uninhabited (Western and Pearl 1989), and only 3.2% is protected in national parks (Reid and Miller 1989), Of the 95% of the world’s land devoted to managed ecosystems, approximately 50% is in agriculture, 20% in commercial forestry, and 25% in human settlements, such as cities, towns, and villages (Western and Pearl 1989). Although the biodiversity of any particular managed ecosystem may be low, a large proportion of the total species of a region may live in such systems (Pimentel et al. 1992). The extent to which biodiversity and ecosystem processes are modified by management varies tremendously. These data suggest that more attention should be paid to understanding patterns of biodiversity in managed ecosystems and how species richness influences the functioning of those systems.
