Opis

To secure lands for migratory birds, the United States Congress established the Migratory Bird Conservation Fund to acquire lands for conservation, to maintain acquired lands for habitat preservation, and to fund expenses necessary for the administration, development, and maintenance of such areas. Associated activities include construction of dams, dikes, ditches, spillways, and flumes for improving habitat and mitigation of pollution threats to waterfowl and migratory birds. The refuges protect habitat with primarily two tools: fee-title ownership and conservation easements.
