Transects are perpendicular and located at 0, 15, 30, and 45 meters. B2 is located directly to <br />the north of B 1, runs along the center of the unit, and is marked with aluminum tags on meta] boundary posts (B°, B45). Transects aze <br />perpendicular and located at 0, I5, 30, and 45 meters. Endpoints of the tansects are mazked with wooden stakes. <br />Herbaceous Cover: Grass = 0.1% coverage. Forb = 2.9% coverage. Coverage by exotic weeds is relatively small within this unit. <br />Coverage by weedy species, however, is expected to expand. <br />Comments: Survival fot Serviceberry, Chokecherry, and Gambel's Oak is generally excellent within this planting unit. Wood's Rose <br />and Mountain Snowberry, as in other units, had a lower survival rate. The reason for this is unclear although browse damage <br />potentially reduced survival rates. Browse damage occurred on 66% of plants and can be expected to increase mortality in the <br />upcoming year. <br />19 <br />
