Careful field records are kept for later analysis by fish and wildlife scientists, such as this log from the Arctic Grayling Recovery project.
The refuge science staff uses a variety of habitat management techniques to maintain, restore or enhance plant and wildlife chances of survival. Refuge staff carefully consider any management techniques and employs them in varying degrees according to the situation. Water levels are carefully monitored and controlled to foster desired plant growth, waterfowl breeding habitat and land stabilization. If required, sensitive areas are closed to the public so that the land, flora or wildlife can recover without the disturbance made by visitors. Prescribed burning, mowing, experimental bio-control insect releases, and seeding are also some of the techniques used to help native plants and wildlife to recover on national wildlife refuges.
Standardized ground and aerial wildlife surveys and vegetation surveys are conducted during certain times of the the year to inventory populations and document habitat use. Units are evaluated by how well they meet habitat and wildlife use objectives.
Public involvement and input are important to the wildlife service and to the planning process, and we hope you will take an active interest in the process, individually and as a community.

In 1932, fewer than 70 trumpeters were known to exist worldwide, at a location near Yellowstone National Park. This led to the establishment of Red Rock Lakes National Wildlife Refuge in 1935. Red Rock Lakes is located in Montana's Centennial Valley and is part of the Greater Yellowstone ecosystem. Nearly half of the known trumpeter swans in 1932 were found in this area. Warm springs provide year-round open waters where swans find food and cover even in the coldest weather.
Today, estimates show about 46,225 trumpeter swans reside in North America, including some 26,790 in the Pacific Coast population (Alaska,Yukon, and NW British Columbia) which winter on the Pacific Coast; 8,950 in Canada; about 9,809 in the Midwest; and about 487 in the tri-state area of Idaho, Wyoming, and Montana (including the Red Rock Lakes refuge flock).
