• 2.2.5 EP037 <br />EP037 is comprised of 21.7 aces of moderately sbping revegetation that has a predominately <br />southeasterly aspect. This unit was seeded in 2001 and reseeded in 2002, and therefore, has undergone <br />one effective growing season prior to sampling in 2003. A total of 18 plant taxa were observed in the <br />untt (see Table 19). <br />Seedling emergence data (Table 16 and 53) from 55 quadrats in EP037 revealed that there was an <br />average of 0.44 perennial seedlings per square foot An average density of 0.42 was attributed to <br />perennial grasses while the remaining 0.02 was from perennial forts. Typically, 1 emergent per square <br />foot is considered modest seeding success, 2 to 4 emergents is reasonably good success, and 5 or more <br />is considered excellent. Although big sagebrush and fourwing saltbush were observed in the unit, no <br />shrubs were documented by quadrat sampling. Annual species, espedally field pennyaess and Russian <br />thistle, dominate the vegetative cover of this unit Wirth an average of 20.44 seedlings per square foot. <br />Woody plant density was recorded from the 55 quadrats, however, since no shrubs were observed in the <br />quadrats, woody plant density (Table 17) totaled 0 young and mature stems per aae. <br />• Noxbus weeds appear to be controlled in this unit There are a few small patches of annual bromes <br />scattered throughout the unit, but they presently are not problematic. The primary concern is that <br />seedling emergence is substandard for first year revegetation, most likely due to the preponderance of <br />annuals, especially Russian thistle. It would be most prudent to give this unlt another growing season <br />with visual observation to occur during July, 2004 to evaluate whether or not additional emergence <br />ocwrs from any viable seed remaining in the seedbed. If seedling emergence is stlll below 2 to 3 plants <br />per square foot folbwing a second growing season, remediation should be considered. Remediatlon <br />could include soils evaluation J amendment, seedbed preparation (e.g, plowing), and reseeding. <br />• <br />KenneCOn Fiieryy Co. ~ Cdowyo 68ne Page 23 Revegetatlon Monnorrnp -2003 <br />
