only in Colorado on Raven Ridge, and along the rim of the White <br />River just west of Raven Ridge. Suitable habitat for both species <br />is exposures of the Parachute Creek member of the Green River <br />Formation which occurs along Raven Ridge and primarily, the north <br />rim of the White River west of Raven Ridge (T 1 N, R 103 W and T 2 <br />N, R 103 W). <br />As far as we are aware, the extreme northern extent of southwestern <br />willow flycatcher (E.t.extimus) breeding range is presumed to be the <br />Colorado River and as such does not encompass this Resource Area. <br />We maintain no further information on this subspecies. Further <br />information may be gained from the U.S. Fish and Wildlife Ecological <br />Services staff in Grand Junction or the informational home page at <br />www.nbs.nau.edu/FNF/PIF/siteinfo.html. <br />Bald eagle occur in the Resource Area primarily as winter residents <br />and migrants with a regular contingent of breeding pair since 1980 <br />(currently 6 active nests along the White River). Migrant and <br />winter residents arrive in October and depart by mid-April. Mid- <br />winter (December-February) populations on the White vary from 50-70 <br />birds, with migratory peaks of up to 160 birds. Migratory and <br />wintering eagles scavenge extensively in open vegetation types <br />throughout the Resource Area, but concentrated use is closely <br />associated with the area's larger riverine systems (e.g. White and <br />Yampa Rivers and Piceance, Coal and Milk Creeks). A number of <br />traditional nocturnal roosts have been identified in cottonwood <br />galleries along the White River corridor and douglas-fir stands <br />within 2 miles of the river. Breeding pairs begin nest selection <br />and establishment in early February, and successful nests fledge <br />young by mid-July. <br />We have no information which indicates that boreal toad populations <br />exist at higher elevations (above 8000') in the Resource Area west <br />of Meeker. There are historic records of this toad at the <br />confluence of the South and North Forks of the White River, <br />although, as far as we know, most recent local records have been <br />confined to the Trapper's Lake area. We understand that little <br />inventory emphasis is being applied to lands below 9000'. Further <br />inquiry should be directed to Colorado Division of Wildlife's John <br />Goettl in Fort Collins. <br />The White River is used throughout the year by adult and fewer <br />subadult squawfish. Squawfish currently represent less than 1 <br />percent of the white River's fish community. Following closure of <br />Taylor Draw dam in 1984, squawfish are confined to the lower 32.5 <br />river miles below the dam. That large numbers of squawfish used the <br />47 river miles above the reservoir was indicated by heavy and <br />prolonged congregations of post-spawn fish below the dam in 1985. <br />An experimental squawfish stocking program (1988-90) above the dam <br />met with little success and has been discontinued. <br />The White River does not appear co support spawning activity, young <br />of year nurseries or juvenile concentration areas for squawfish in <br />Colorado, however, portions of the lower White River in Utah serve <br />
