Fort Wainwright and associated lands (USARAK 1999).Reptiles and AmphibiansThe wood frog is the only amphibian species found at Fort Wainwright. No reptiles exist on FortWainwright.FisheriesMost ponds or lakes on Fort Wainwright do not support fish populations during winter.

These rivers and clear-running tributaries are importantspawning areas for summer chum and king salmon. Horseshoe Lake, located in the northwest corner ofthe Yukon Training Area, supports a native population of northern pike (BLM and U.S. Army 1994).Donnelly Training AreaMammalsLarge mammals on Donnelly Training Area include black bear, grizzly bear, moose, Dall sheep, caribou,and bison. Donnelly Training Area typically has three or four wolf packs, although the structure,distribution, and numbers of packs in a given area are highly variable. Other furbearers on the trainingarea include lynx, beaver, river otter, pine marten, muskrat, mink, coyotes, red fox wolverine and fourspecies of weasel. Anderson et al. (2000) conducted a small mammal survey at Donnelly Training Area.Eleven species of small mammals were found in this study.Avian SpeciesSeveral upland game species are found on Donnelly Training Area, including three species of bothptarmigan and grouse. Twenty-eight species of ducks and geese use lands and waterways on the trainingarea. Approximately 300,000 sandhill cranes, a large portion of the world’s population, migrate throughDonnelly Training Area from late April through mid-May.Anderson et al. (2000) reported sightings of black-backed woodpecker, gray-cheeked thrush, variedthrush, bohemian waxwing, Townsend’s warbler, blackpoll warbler, Smith’s longspur, and rustyblackbird.
