Tr <br />ansit Mix Concrete Co. <br />Riparian woodland is found along the perennial Little Turkey Creek and the downstream portion <br />of an unnamed seasonal tributary to it that passes through the southern third of the property. This <br />community is confined to a narrow band along each stream, occupying a total of 22 acres (1%) <br />on the property. The principal tree species throughout is narrowleaf cottonwood (Populus <br />angustifolia), with Douglas fir, blue spruce, ponderosa pine, alder (Alnus incana), and river birch <br />(Betula occidentalis) also important where Little Turkey Creek runs through the foothills. Plains <br />cottonwood (Populus deltoides) occurs scattered throughout the riparian woodland. Where Little <br />Turkey Creek passes near the residence area, the introduced Siberian elm (Ulmus pumila) <br />becomes common. The principal shrub species is bluestem willow (Salix irrorata), with associated <br />coyote willow (Salix exigua), pin cherry (Prunus pensylvanica), chokecherry, red -osier dogwood <br />(Corpus sericea), Rocky Mountain maple, rose (Rosa sp.), and highbush cranberry (Viburnum <br />edulis). Woodbine (Parthenocissus vitacea) forms a dense cover over shrubs and poison ivy <br />(Toxicodendron rydbergu) is common in some places. After the creek passes out of the foothills, <br />Gambel oak and three -leaf sumac are common at the top of bank. The often dense shrub layer <br />results in a generally sparse understory of forbs and grasses in most places. Principal forbs and <br />grasses vary widely and include cow parsnip (Heracleum maximum), giant hyssop, smooth brome <br />(Bromus inermis), and redtop bent grass (Agrostis gigantea or A. stolonifera). A fringe of the <br />introduced green ash (Fraxinus pennsylvanica) occurs around the southern side of the main lake. <br />Dalmatian toadflax (Linaria dalmatica, occurs along the road that follows Little Turkey Creek in <br />the foothills. Common teasel (Dipsacus fullonum), Canada thistle, (Cirsium arvense), and bull <br />thistle (Cirsium vulgare) also occur. Average cover and height estimates for the principal plant <br />species in this community are provided in Table 4. <br />Hitch Rack Ranch Quarry Permit Application M-2016-010 <br />July 14, 2016 J-6 <br />
