National Wildlife Refuge System Improvement Act of 1997:The NWRS Improvement Act defines a unifying mission for all refuges, including a process for determining compatible uses on refuges, and requiring that each refuge be managed according to a CCP. The NWRS Improvement Act expressly states that wildlife conservation is the priority of System lands and that the Secretary shall ensure that the biological integrity, diversity, and environmental health of refuge lands are maintained. Each refuge must be managed to fulfill the specific purposes for which the refuge was established and the System mission. The first priority of each refuge is to conserve, manage, and if needed, restore fish and wildlife populations and habitats according to its purpose.
Delevan National Wildlife Refuge is best known for migratory waterfowl. Waterfowl are present September through April and numbers regularly peak at over 300,000 ducks and 100,000 geese. The refuge supports one of the largest known populations of palmate-bracted birds-beak (Federally listed endangered plant species) and significant breeding colonies of tricolored blackbirds. Delevan is also an important wintering grounds for Tule Greater White-fronted Geese.
