Snowpack in 1995 prevented an accurate count for baseline comparison. <br />**Survival based on original number of individual plants per transect. <br />Location: Two baselines were used due to the "L" shape of the site. B1 runs along the southeast border of the site (B°, B39). <br />Transects are perpendicular and located at 0, 13,26, and 39 meters. B2 is a continuation of B 1 (B39, Bx). Due to the small azea of the <br />second section, the first transect of B2 was laid perpendicular at the 13 meter mazk and the second transect runs diagonal between the <br />starting point of B2 and a wooden fence post placed in the center of this section. Endpoints of the transects are marked with wooden <br />stakes. <br />Herbaceous Cover: Grass = Q.3% coverage. Forb = 12.3% coverage. Alfalfa (Medicago sp.}, Prickly Lettuce (Lactuca sp.) and <br />Canada Thistle (Cirsium arvense) were the common weeds on the site. The Thistle and Prickly Lettuce present a future weed <br />problem. <br />Comments: An overall survival rate of 54% was observed on Unit 95-3. Browse rate increased from 47% to 88% between annual <br />monitoring visits. Continued browse will result in future mortality on this site. Browse disturbance on weedy species could also be a <br />factor for increased weed distribution of this site. Observational data showed Prickly Lettuce to have been highly browsed, most <br />likely causing an increase in lateral vegetative growth and an overall increase in coverage. <br />9 <br />
