• 2.0 SURVEY RESULTS
<br />2.1 FIELD INVESTIGATION
<br />The surveyed area is largely oak brush with scattered Douglas-fir and Rocky Mountain juniper.
<br />There are several underground seeps on the steep hillside with small patches of narrowleaf
<br />cottonwood, willow, and birch. Narrowleaf cottonwoods also occur along Sylvester Gulch which
<br />has a trickle of surface water. A small artificial wetland created by the embankment of Highway
<br />133 is near the east end of the area and contains cattails, willows, cottonwoods, and sedges. The
<br />fallowing species or genera were observed
