  Wildlife and Habitat

Continued . . .

Less than 5 percent of the land area in Wyoming is wetland, making wetland communities within the State particularly important to wildlife. The heart of the Refuge is the mosaic of wet meadows and cattail/bulrush sloughs. Many of these wetlands were originally created and maintained by agricultural practices.

The area, recently nominated as an Important Bird Area by Audubon Wyoming, provides nesting habitat for 32 water bird species including sandhill cranes, white-faced ibis, black terns, black-necked stilts, American bitterns, and a variety of waterfowl, marsh, and shorebirds. If developed, these wetlands may someday provide suitable nesting habitat for trumpeter swans.

Refuge habitats also provide important habitat for resident species. Greater sage grouse use upland sagebrush areas for nesting while riparian areas provide important feeding sites for their broods. Big game, including antelope, mule deer, and elk also utilize Refuge habitats.

While Cokeville Meadows NWR features a unique diversity of wildlife, the climate can be harsh. At 6,200 feet above sea level, the frost-free season is only 60-70 days long. The semi-arid climate yields an average of 12.05 inches of precipitation annually. Temperatures are often below zero degrees Fahrenheit in the winter, but they can exceed 90 degrees Fahrenheit during the summer.
