mud bottoms and shallow banks are preferred. Usually not present in water sources with predatory fish. Northern Leopard Frog (Rata dens) The northern leopard frog inhabits riparian areas, ponds, marshes, lakes and wet meadows. Wet areas with rooted aquatic vegetation aze especially favored. Breeding takes place in shallow non-flowing bodies of water at elevations up to 10500 feet. During summer, adults prefer grassy areas, wet meadows and swampy azeas surrounding pools and marshes. Areas with 100% vegetative cover are preferred. Frogs can cover large distances (3 miles) in dispersal and feeding range. Feeds mostly on arthropods: beetles, crickets, grasshoppers, aphids, ants, spiders, flies, caddisflies, etc. ). Milk Snake (Lampropeltis trian rig him) The milk snake occurs in a wide variety of habitats in Colorado including grasslands, sandhills, canyons and open stands of ponderosa pine in the foothills, pinyon juniper woodland, and acid river valleys. Milk snakes usually emerge from their subterranean winter retreats in April in eastern Colorado; perhaps later in western Colorado. After emergence, milk snakes remain active until September or October. This snake is a constrictor and eats a variety of vertebrates, including small mammals, birds, lizazds, snakes, and bird and reptile eggs. FISH Colorado River Cutthroat Trout (Oncorhvnchus clarkipleuriticus). Stream habitats with clear cold water, silt-free rocky substrate in riffles/runs, azeas of slow deep water, well vegetated stream banks, abundant instream cover, relatively stable water flow and temperature regimes. Lake habitat is clear, cold, deep. For reproduction, needs lake tributary streams with gravel substrate in riffles. PLANTS Gunnison Milkvetch (Astrealus anisus) Found on dry gravelly flats and hillsides, in sandy or clay soils overlying granitic bedrock; usually among or under low sagebrush; 7,500-8,500 feet elevation. Molybdenum Milkvetch (Astr~aalus molvbdenus) Grows in tundra, subalpine exposed sites above treeline, and calcerous scree slopes; 11,000 to 13,000 feet in elevation. Smooth Rockcress (Brava zlabella) Grows on alcerous substrates, scree slopes, disturbed gravel soils; 12,000 to 12,300 feet in elevation.
