Does not include noxious perennial weeds. <br />*2. Allowable cover = perennial cover minus noxious perennials, plus up to 10% relative annual cover, plus litter <br />cover up to the maximum allowed per range site. Allowable cover bond release standards are as follows: <br />Range Site A = 52%: herbaceous cover at least 33%, litter cover up to 19%. <br />Range Site B = 52%: herbaceous cover at least 29%, litter cover up to 23%. <br />Range Site C 47%: herbaceous cover at least 25%, litter cover up to 22%. <br />w *3. Stem density bond release standard = 400 stems/ac for A and B range sites. No standard for range site C. <br />*4. The minimum sample size requirement established by DRMS is 15. <br />*5. Refer to sample adequacy summary (Table 2 in attached Crofts' report). <br />*6. Reverse null T-Test on mean to demonstrate revegetation success used rather than sample adequacy equation (refer to Table 2.2-1).
