There are two species, Boreal Toad (Bufo boreas boreas) and Northern Leopard Frog <br />(Rana nipiens), that are known to occur in Routt County due to sightings and/or habitat. These <br />species were not sighted in the 1979 to 1980 study on site or adjacent to the mine site. <br />Boreal Toad preferred habitat is in damp conditions in the vicinity of marshes, wet <br />meadows, streams, beaver ponds, glacial kettle ponds, and lakes interspersed in subalpine forest <br />(lodgepole pine, Englemann spruce, subalpine fir, and aspen). This species occurs throughout <br />much of western North America, ranging from southeastern Alaska to northern Baja California, <br />Utah, and northern New Mexico. The mountain toad is restricted to the southern part of the <br />Rocky Mountains. The elevational range is mainly 8,500-11,500 feet (2,600-3,500 m), with <br />higher and lower occurrences in some areas. This species is known to occur in Routt County <br />although its abundance is rare. <br />Northern Leopard Frog preferred habitats include wet meadows and the banks and <br />shallows of marshes, ponds, glacial kettle ponds, beaver ponds, lakes, reservoirs, streams, and <br />irrigation ditches. Southern Canada and northern United States south to Maryland, West <br />Virginia, Kentucky, northern Illinois, extreme northwestem Missouri, Nebraska, New Mexico, <br />Arizona, and eastern California. This species occurs throughout Colorado, excluding most of the <br />southeastern and east-central portions of the state. The elevational range extends from below <br />3,500 feet (1,065 m) in northeastern Colorado to above 11,000 feet (3,355 m) in southern <br />Colorado. This species is known to occur in Routt County and is fairly common in abundance. <br />As the mine is in permanent cessation no impact to the species in Colorado that are <br />threatened, endangered or species of special concern at the state and/or federal levels or habitat is <br />expected. <br />2.7.2.5 Reptiles <br />Threatened and Endangered Species <br />The following is the current listing of wildlife species in Colorado that are <br />threatened, endangered or species of special concern at the state and/or federal levels. Each <br />species is described by conunon and scientific names, status and occurrence and abundance in <br />Routt County. <br />2.7-63e Revised 11/06 <br />
