are believed to be extirpated in Colorado with the crane at best a historic migrant. In addition to the federal list, the State of Colorado lists an additional 6 threatened and 10 endangered species, but only the endangered boreal toad (B fo boreas boreas)and threatened western burrowing owl (Athene cuniculari(i)occur Nvithin La Plata County. Of the listed species, only the Canada lynx and its habitat is of In the following, the habitat for each listed species believed to occur within La Plata County is summarized and related to their potential to be impacted within the project boundaries(Appen- dix R-2). • Boreal toad: southern Rocky Mountain boreal toad occupies forest habitats between 7,500 to 12,000' elevation within lodgepole pine, spruce-fir forests, and alpine meadows with proximity to shallow, quiet water in lakes, marshes, bogs, ponds, and wet mead- ows3. However, as of summer 2000, the boreal toad is not known to occur in L,a Plata County. • Mexican spotted owl: the owl, in the San Juan Mountains of southwestern Colorado, in- habits closed-canopy mixed conifer and spruce-fir forests; nesting and roosting primarily in sheer, slick-rock canyons or steep canyons containing exposed bedrock cliffs`r. This habitat is not present within affected areas and limited within the nearby landscape. • Southwestern willow flycatcher: the flycatcher is a riparian habitat bird ranging from near sea level to 6100 feet 5; La Plata River floodplain has dense willow thicket habitat as required by the flycatcher, but is at 8600 feet. The La Plata River floodplain is not within the Affected Lands will not be impacted by this project. • Yellow-billed cuckoo: the cuckoo is a riparian habitat bird; the cuckoo is nearly extirpat- ed in the West and National Park Service surveys in southwest Colorado from 1988 through 1995 for the Colorado Bird Breeding Atlas have no records of yellow-billed cuckoo. The cuckoo is not expected to occur on the site and the La Plata River floodplain will not be impacted by this project. • Western burrowing owl: the owl occupies grasslands with large prairie dog colonies. This habitat is not present within affected areas or the nearby landscape • Colorado pikeminnow: the pikeminnow inhabits pools of medium to large rivers in swift flowing muddy rivers with quiet, warm backwaterss. Potential habitat for the pikeminnow would be miles downstream from the project within the Colorado River Ba- sin. Further investigation of this indirect impact is not required since there is not Federal Action triggered by this project (pees. comm. Patty Gelatt, U.S. Fish and Wildlife Ser- vice, July 15, 2010). • Razorback sucker: the sucker inhabits silt-bottomed to rock-bottomed backwaters near strong current and deep pools in medium to large rivers, and impoundutents8.
