• <br />Added 11/21/33 <br />2) An average density of 2,000 shrubs/acre has been <br />established after the ten year liability period; <br />3) Two~h n~h ~pP~~es, two perennial cool season grasses and <br />one forb have been established. <br />• <br /> <br />The shrub density standard is considered reasonable because <br />shrubs take many years to become established and 2,000 stems/acre <br />should_~rovd~._an_adequate_initial_. col.an-i-za.ti.o~s.~oc-k-from-arh-}c-h_ <br />succession will yield a more desirable shrub cover. <br />The diversity standard was developed by considering the pre- <br />mine cumulative relative cover provided by each species in the <br />sagebrush vegetation type. The sagebrush type was used for this <br />calculation because of its relative importance on the Bourg <br />property. Eighty-eight percent (88:) of the cover was provided <br />by two shrubs, two grasses, and one weed (see table 4(bl)). <br />Although forb species do not provide significant cover at the <br />Bourg property, they are considered important in a diversified <br />habitat, and therefore, at least one forb species will be <br />established. <br />F-11(a) <br /> <br />
