Larch Mountain Salamander (Plethodon larselli) is a species of salamander in the family Plethodontidae. It is endemic to the United States. The Larch Mountain salamander occurs in the Cascade Mountains of southern Washington and northern Oregon. In Washington, it occurs from the Columbia River Gorge to just north of Snoqualmie Pass. Its natural habitats are temperate forests and rocky areas.
Van Dyke's Salamander (Plethodon vandykei) is a salamander in the order Caudata and the family Plethodontidae. Like most terrestrial salamanders Van Dyke's Salamander lives near lakes, rivers, and streams under various objects such as rocks, logs, and bark. Salamanders' habitat range from wide open lowlands up to heavily wooded mountains. It is in this wood that they lay their eggs. The species is endemic to the western portion of the state of Washington, northern Idaho, and northwestern Montana in the U.S. It is predominantly located in hilly or mountainous regions such as the Olympic Hills, the Willapa Hills and the Cascade Mountains.
Western Toad (Anaxyrus boreas) more commonly known as Bufo boreas (both names accurate) is a large toad species, between 5.6 and 13 cm long, of western North America. The range of western toad extends from western British Columbia and southern Alaska south through Washington, Oregon, and Idaho to northern Baja California, Mexico; east to Montana, western and central Wyoming, Nevada, the mountains and higher plateaus of Utah, and western Colorado. In the Pacific Northwest, the western toad occurs in mountain meadows and less commonly in Douglas-fir forests.
Rubber Boa (Charina bottae) are the most northerly of boa species. The distribution of Rubber Boas covers a large portion of the western United States, stretching from the Pacific Coast east to western Utah and Montana, as far south as the San Bernardino and San Jacinto Mountains east of Los Angeles in California, and as far north as southern British Columbia. Rubber Boas have been known to inhabit a wide variety of habitat types from grassland, meadows and chaparral to deciduous and conifer forests, to high alpine settings. They can be found at elevations anywhere from sea level to over 10,000 feet (3,000 m).
Wandering Garter Snake(Thamnophis elegans vagrans) is a subspecies of the Western Terrestrial Garter Snake, a species of colubrid snake residing only in Southwestern Canada, and Western United States. Seven subspecies are currently recognized. Most snakes have a yellow, light orange, or white dorsal stripe, accompanied by two stripes on its side of the same color. Some varieties have red or black spots between the dorsal stripe and the side stripes. This snake often inhabits coniferous forests, and is relatively aquatic.
Valley Garter Snake(Thamnophis sirtalis fitchi) is a subspecies of the common garter snake. It is a snake indigenous to North America. Most garter snakes have a pattern of yellow stripes on a brown background and their average length is about 1 metre (3.3 ft) to 1.5 metres (4.9 ft). The common garter snake is a diurnal snake. In summer, it is most active in the morning and late afternoon; in cooler seasons or climates, it restricts its activity to the warm afternoons.
