Snowpack in 1995 prevented an accurate count for baseline comparison. <br />**Survival based on original number of individual plants per transect. <br />Location: Planting Unit 95-4 is divided"into two sepazate units as part of an ongoing study. Planting Unit 95-4A is, on the non- <br />topsoiled portion of the study site., The baseline runs along the west border of the site (Bo, B40) with endpoints at metal posts marked <br />with aluminum tags. Transects are perpendiculaz and located at 3, 10, 14, 18, 20, 24, 30, 32; 36, and 44 meters. Endpoints of the <br />transects are mazked with wooden stakes. <br />Herbaceous Cover: Grass = 0.0 % coverage. Forb = 3.4 %-coverage'.- Minor"amounts of herbaceous cover exist on the site. Noted <br />was Thistle (Cirsium arvense) which presents a potential future weed problem. <br />Comments: The overall survival rate remained relatively unchanged at 87% and 85% between 1996 and 1997 respectively. <br />Gambel's Oak survival exceeded 100% which resulted from the resprouting of individual plants previously noted as dead. Several <br />large thistle were observed growing throughout the plot which is a noticeable increase from 1996.. Several shrub seedlings were <br />covered and crowded by thistle. The impact of plant competition caused by the thistle versus the protective benefit received by shrubs <br />from browsing is unknown. Several plants were buried by sediment running off of the slopes. <br />10 <br />• • <br />
