Public grasslands must play a major role in the preservation and enhancement of avian communities because, as compared to other broad habitat types, a disturbingly high percentage of native grassland in the U.S. already has been destroyed or badly abused, and there is relatively little public grassland available for management. The general features of avian grassland communties form a foundation for management are: (1) low species diversity, (2) numericaldominance by 1 or 2 widespread, eurytopic species, and (3) the presence of a few stenotopic species. A management approach is proposed that is designed to maintain all existing functional elements of a grassland avian community. Other management aspects addressed include habitat conversion practices, water management, grazing, size of land holdings, timing of human activities, and the use of artificial structures in avian management.
