Cold Springs National Wildlife Refuge and Reservoir

Habitat At Cold Springs Reservoir

A mix of several distinct habitat types?open water, riparian, shrub-steppe upland and seasonal wetlands?attracts a variety of wildlife to the refuge. The open water habitat of the reservoir provides isolation for the resting needs of migrating waterfowl. Large numbers of waterfowl, primarily Canada geese and mallards, can be seen on the open water in winter. They move between the reservoir and the river daily, looking for food or quiet space.

Dense, wide stands of cottonwoods and willows represent the riparian zones on the Cold Springs National Wildlife Refuge. The area where water meets the land is especially important because it offers wildlife many food and shelter choices. The thick underbrush provides excellent habitat for many species of songbirds. It is also a good place to look for deer, elk and other animals feeding or resting.

The shrub-steppe upland consists of sagebrush, bitterbrush, rabbitbrush and native bunchgrasses. Mule deer, coyotes, badger, ring-necked pheasant, California quail, and the small resident elk herd can be seen using the uplands throughout the year. Look for Swainson?s, Coopers and red-tailed hawks and American kestrels soaring over the uplands.

The shrub-steppe, representative of plant communities once very common in this part of the country, is threatened by invasive exotic plants, such as cheatgrass, false indigo and Russian olive. The native plants cannot compete for water and nutrients as well as these exotics, which thrive in stressed or disturbed conditions. Wildlife, having been sustained for ages by native plants, start to decline because exotic plants do not typically provide the needed food nor shelter.
