<br />Table 3. Shrub densities for Herbivory Study Plot 95-1. <br /> <br />Species 1997 Density <br />per Plot- 1995 Density <br />per Plot 1997 <br />Frequency % Survival* <br />Serviceberry 68 160 100% 43% <br />Chokecherry 113 160 100% 71% <br />Gambel's Oak 139 160 100% 87% <br />Totals 320 480 100% 67% <br />na=not applicable <br />*Survival based on original number of individual plants per transect. <br />Location: Planting Unit 95-1 was planted within a randomized grid system as part of an herbivory study at the site. <br />Herbaceous Cover: Grass = 0.0% coverage. Forb = 6.9% coverage. Forb cover consisted primazily of both perennial and annual <br />species, Canada Thistle (Cirsrum arvense) and Kochia (Kochia scoparia). Forb coverage represents a substantial increase over 1996 <br />levels. <br />Comments: Survival rates declined from 73% in 1996 to 67% in 1997 with Serviceberry and Chokecherry experiencing the largest <br />declines. The area was heavily browsed by marmots, deer, and elk. Note that density numbers aze on a per plot rather than per acre <br />basis due to the sampling method utilized for the study. <br />
