• 2.3.5 WPOll <br />WPOll is comprised of 1.7 aces of moderate to steeply sloping revegetation that has a <br />predominately northeasterly aspect. This unit was seeded in 2001 and therefore, has undergone two <br />growing seasons prior to sampling in 2003. A total of 29 plant taxa were observed in the unit (see Table <br />19). <br />Ground cover (Fgure 13) wnsisted of 55.2% live vegetation, 1.5% rock, 3.2% standing dead, <br />14.5% litter, and bare soil exposure of 25.6%. Perennial cover across the unit averaged 8.7% with <br />annual and biennial cover averaging 46.5%. The dominant taxa were field pennycress, Russian thistle, <br />and streambank wheatgrass with 22.5%, 21.8%, and 1.8°h average cover, respectively. Woody plant <br />density was determined from 15 bek transacts and totaled 8 young and mature stems per acre (Table 2) <br />with fourwing saltbush the dominant woody plant. <br />Noxious weeds appear to be well controlled in this unit and the annual brome populations are <br />subdued unit-wide. Although cover by the early-seral species, field pennycress and Russian thistle, is <br />elevated, ground Dover by perennials appears sufficient to progress to dominance over the next few <br />• years. The shrub population is very modest, and is comprised primarily of four-wing saltbush. Overall, <br />the unit appears typical of reasonable two-year old revegetation, therefore no recommendations are <br />proffered other than continued monitoring, especially during the fourth growing season (2005). <br />J <br />rcennecorc aegy Co. icaay° IIrU~a Page 47 Revegetaflon 1laonnorrng - 2003 <br />
