Conclusions <br />The following conclusions are provided based upon analysis of the data: <br />Shrub densities range from 607 (96-1) to 4079 (97-1 d) stems per acre. The high <br />vaziability in densities is related to differences in planting density and percent survival. <br />Better estimates of site acreage prior to outplanting could increase the evenness with <br />which sites aze planted and reduce costs associated with over planting. <br />2. Shrub survival varied widely by species. Gambel's oak survival ranged from 70 to 90%. <br />Chokecherry and serviceberry survival ranged generally from 32 to 90%. Bitterbrush <br />survival was 25% and aspen was 50% although these species both occurred in a single <br />plot. Wood's rose (13-100%) and snowbeny (18-30%) survived poorly in all planting <br />units with few exceptions. <br />Seeding efforts and seed bank recruitment appeaz to enhance shrub densities on several <br />sites. Seeding of shrubs should be investigated on an experimental basis as a possible <br />method for woody plant establishment. <br />4. Browse damage is the primary factor limiting woody plant establishment. Approximately <br />17 to 66% of plants were observed with browse damage. Browse has resulted in <br />substantial mortality and poor growth. Deer proof fencing and hunting are necessary to <br />increase survival and growth rates on these sites. <br />Plant competition does not limit woody plant establishment. Total competing coverage <br />ranged from 6.8% to 22.9%. Canada thistle is a species of concern and should be <br />controlled through spot spraying of individual plants. Also, aggressive grass species such <br />as crested wheatgrass should not be planted on woody plant establishment plots. <br />6. Lack of plant cover is resulting in minor erosion problems on several planting units. It is <br />recommended that anon-aggressive, short lived grass or forb species be planted on these <br />sites. A cover crop will both reduce erosion and conceal plants from herbivores. <br />]0 <br />
