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.
Water levels are carefully monitored and controlled to foster desired plant growth. Sometimes, sensitive areas are closed to the public so that the land can recover more quickly. 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.

American bitterns are almost always solitary and can be difficult to see. They often hide among wetland vegetation, walking slowly as they forage. American bitterns typically hunt in low light, catching food with their bill and killing prey with biting or shaking movements. Flight is stiff and fairly clumsy with rapid wingbeats.
