Adults have tiny, almost unnoticeable toe pads; a dark line extends from the snout through the eye to the groin. Basic coloration varies, with background color green, brown, gray, or reddish. Typically three to five dark longitudinal stripes are present on the head and back; in some individuals the stripes may be broken into spots. Adult body length is 0.75 to 1.5 inches. Eggs and Tadpoles: Eggs are laid in clusters of 20 to 100; clusters are usually less than 1 inch across and attached to submerged vegetation. Tadpoles are brown/bronze with eyes located on the sides of the head. Boreal Chorus Frogs are regularly found in the water only during the breeding period in spring. They announce their presence this time of year by calling frequently at night and sporadically during the day. Following breeding, they move into adjacent uplands and are rarely seen. In eastern Montana, they breed in temporary ponds and small lakes surrounded by prairie (or occasionally open forest) habitats. Eggs hatch in about 2 weeks and tadpoles take 8 weeks to metamorphose. Inhabits marshes, ponds, small lakes in all life zones including lower alpine (Baxter and Stone 1980). When not breeding, generally found in damp grassy/marshy areas or damp forests near water, but has been found up to 0.5 km from water (Nussbaum et al. 1983, Hammerson 1982).

Once common in montane habitats between 7,000-12,000 feet in the Southern Rocky Mountains, the boreal toad (Bufo boreas boreas) has experienced dramatic population declines over the past two decades. Reasons for the declines appear to be related to infection by the chytrid fungus Batrachochytrium dendrobatidis (Bd). The boreal toad is presently listed as an endangered species by both Colorado and New Mexico, and is a protected species in Wyoming. The U.S. Fish and Wildlife Service had classified the Southern Rocky Mountain population of the boreal toad in 1995 as a candidate species which is "warranted but precluded" for federal listing - meaning there was adequate justification and information to warrant federal listing as threatened or endangered, but listing was postponed. In 2005 this designation was removed while the distinctness of the Southern Rocky Mountain population is reevaluated. Pursuant to the listing of the boreal toad as endangered in Colorado in 1993, the Colorado Division of Wildlife developed a recovery plan for the boreal toad in 1994, and an interagency recovery team was formed that same year. In 1998, the existing Recovery Plan was updated and combined with an existing draft Conservation Strategy to create a comprehensive Boreal Toad Conservation Plan for the Southern Rocky Mountains. As part of the conservation planning process, Conservation Agreements have been signed by eight state and federal agencies, and by the Colorado Natural Heritage Program, outlining and confirming respective roles in implementing the Conservation Plan
Tiger salamanders' markings are variable throughout their extensive range, but the most common marking resembles the vertically striped pattern of their mammalian namesake. They are usually brown in color with brilliant yellow stripes or blotches over the length of their bodies. Their base color, however, can also be greenish or gray and their markings can be yellow dots or brown splotches. Some have no markings at all. Thick-bodied amphibians with short snouts, sturdy legs, and long tails, tigers are the largest land-dwelling salamander on Earth. They can grow to 14 inches (35 centimeters) in length, but the average size is more like 6 to 8 inches (15.2 to 20.3 centimeters). They are also the most wide-ranging salamander species in North America, living throughout most of the United States, southern Canada, and eastern Mexico. They live in deep burrows, up to two feet (60 centimeters) below the surface, near ponds, lakes, or slow-moving streams and are one of few salamanders able to survive in the arid climate of the North America interior.
