<br /> <br />Attachment No. 2 <br />1983 Shrub Density Monitoring Data <br />The following shrub density/establishment monitoring transects <br />were permanently established during the summer of 1983. Initial density <br />of shrubs was estimated on each permanent 50 X lm' transect. General <br />observations of established shrubs, regeneration, and overall vegetation <br />establishment in the transect area was noted. These transects will <br />be monitored annually to establish developmental patterns and trends <br />within the shrub communities. <br />Transect No. 1: Located on a west facing slope. No shrubs occurred <br />in the transect, but mountain big sagebrush (Artemisia tridentata <br />vaseyana) is establishing in the areas around the transect. Silvery <br />lupine (LUpinus argenteus) and American vetch (Vicia americana) are <br />reestablishing well. Good grass/alfalfa (Medicago sa tiva) cover and <br />regeneration. <br />Transect No. 2: Located on a gentle southwest slope near a small <br />depression. No shrubs occured in transect. Good topsoil materials, <br />but overall stand is rather poor. Native farb regeneration is good. <br />Fairly recent reclamation. <br />Transect No. 3: Located on a northwest facing slope. 3 mountain <br />big sagebrush in transect (246 stems/acre). Good sagebrush and native <br />farb regeneration. Good vegetative cover. <br />Transect No. 4: Located on a north facing slope. Eleven mountain <br />big sagebrush, 2 mountain snowberry (Symphoricarpos oreophilus) in <br />transect (1,065 stems/acre). Good grass cover with good stand of <br />established sagebrush. <br />Transect No. 5: Located on southwest facing slope. Six mountain <br />big sagebrush, 1 chokecherry IPrunus virginiana) in transect (574 <br />stems/acre). Areas adjacent to transect have good sagebrush and snowberry <br />regeneration. <br />Transect No. 6: Located on west facing slope. Five mountain big <br />sagebrush and 3 mountain snowberry in transect (656 stems/acre). <br />Very good cover with good American vetch reestablishment. <br />Transect No. 7: Located on gently sloping northwest slope. One mountain <br />big sagebrush, 6 mountain snowberry, 1 chokecherry, 1 gambel oak (Quercus <br />gambelii) in transect (738 stems/acre). Very good shrub and native <br />forb regeneration in areas adjacent to the transect. <br />Transect No. 8: Located on a southwest facing slope. Thirty-four <br />mountain big sagebrush, 2 mountain snowberry in transect (2,950 stems/acre). <br />Excellent regeneration in surrounding area. <br />
