22. Unknown Inactive Aspen 38 58 02.0 N <br />107 26 16.0 W <br />23. Unknown Inactive Aspen 38 57 56,4 N <br />107 26 47.7 W <br />24. Unknown Inactive Aspen 38 58 31,4 N <br />107 27 46.0 W <br />25. Unknown Inactive Aspen 38 50 58.6 N <br />107 27 42.4 W <br /> <br />No nests were found in oakbrush/mountain shrub or in pinyonyuniper. The lack of nests <br />in oakbrush/mountain shrub was not unexpected, as none have been found in this habitat <br />type during five years of surveys conducted in the North Fork Valley. This has also been <br />the case at studies conducted elsewhere in Colorado over the past 10+ yeazs. Like <br />oakbrush, the lack of nests in Pinyon-Juniper (P-J) was not unexpected. Raptors will nest <br />in Pinyon-Juniper, and have been observed nesting in P-J in other azeas. However, none <br />have been found nesting in this habitat type at other study areas in the North Fork Valley. <br />Data collected do not indicate that, within habitat types where nests were found, any <br />particulaz azea was selected over another. However, with few exceptions, nests are <br />located within 150 feet of tree stand edges, and all nests were located in mature stands <br />with wide spacing of trees and crown cover of 60% or less. <br />All red-tailed hawk nests were located in open mature aspen stands. These nests were all <br />located within 300 feet of an active road or ATV trail. When last checked, young were <br />observed on all these nests. These nests were all located neaz open meadows where <br />primary prey species such as ground squirrels are more accessible. <br />Sharp-shinned and Cooper's hawk nests were found in both mature Aspen and Douglas- <br />fir stands. Aspen stands where nests were found were in gently sloping (less than 10%) <br />terrain. Just the opposite was true of those nests found in Douglas-fir stands. These <br />stands aze located primarily in side drainages associated with Beaz and Elk Creeks. <br />These stands are on slopes that are 50% or steeper. Nests for these species were found <br />neaz the edge of mature open stands of Aspen and Douglas-fir where there was little <br />understory. Prey species were commonly observed along the ecotones between these <br />stands and nearby habitat types. <br />An active golden eagle nest was located while conducting wildlife surveys for another <br />project. This nest is located off the project azea in a cliff west of Hubbard Creek and <br />south of Terror Creek Reservoir (Figure 1). This cliffhas been checked for nesting <br />activity for 5 yeazs. One inactive raptor nest was observed during the first yeaz of <br />studies, but no active nests until this yeaz. This nest is within 1/2 mile of Iron Point and <br />Hubbazd Creek. The nest is located over a ridge and out of sight from any proposed <br />activity in the Hubbard Creek drainage. <br />12 <br />
