To help plants and wildlife, refuge staff uses a variety of habitat management techniques to maintain, recover or enhance plant and wildlife values. Refuge staff carefully considers any management techniques and employ them in varying degrees according to the situation.
Sometimes, sensitive areas are closed to the public. Prescribed burning, mowing, experimental bio-control insect releases, and seeding are also some of the techniques used to help native plants recover on national wildlife refuges.
Standardized ground and aerial wildlife surveys and vegetation surveys are conducted on some refuges throughout the year to inventory populations and document habitat use. Units are evaluated by how well they met habitat and wildlife use objectives.
Public involvement and input are important to us and to the planning process, and we hope you will take an active interest in the process, individually and as a community.
