Book excerpt: Excerpt from Basis for Judging Subalpine Grassland Ranges of Oregon and Washington In summary, it is evident not only that green fescue, as the major component of the near-climax vegetation, is of high value for grazing. But also that livestock preference for it remains essentially the same irrespective of the amount present. Furthermore, discrimination against second weed - stage needlegrass appears to be relatively con stant so long as any green fescue remains. It is obvious that if the Tenderfoot Basin area should be grazed to the intensity observed on the Blue Mountain area, namely, so that more than half of the needlegrass herbage is utilized, the green fescue would be greatly overused, soil trampling intensified, and further range deterioration invited. Oh the other hand, moderate use of the fescue. With yerv light utilization of the associated less-palatable species, subalpine needlegrass in particular, is doubtless essential to retard the erosion process and to allow return of climax soil and vegetation conditions. These combined attributes warrant the selection of green fescue as a species key to the grazing management of subalpine ranges on which it occurs.

Book excerpt: This publication documents over 90 years of plant succession on green fescue grasslands in the subalpine ecological zone of the Wallowa Mountains in northeast Oregon. It also ties together the work of four scientists over a 60-year period. Arthur Sampson initiated his study of deteriorated rangeland in 1907. Elbert H. Reid began his studies of overgrazing in 1938. Both of these individuals utilized high-elevation green fescue grasslands in different locations in the Wallowa Mountains for their study areas. Then in 1956, Gerald Strickler returned to the sites previously studied by Sampson and Reid to establish the first permanent monitoring points when he located and staked camera points they had used. He also established line transects where he photographed and sampled the vegetation to benchmark the condition of the sites. In 1998, on the 60th anniversary of the Reid camera points in Tenderfoot Basin, the author returned to document the changes in the vegetation on the Sampson and Reid sites establishing photographic comparisons and resampling the transects Strickler had established. When Sampson and Reid conducted their initial studies, domestic sheep had overgrazed the vegetation leading to severely eroded soils and weakened native vegetation. In recent years, the presence of domestic sheep had declined dramatically. As a result, vegetation trends were generally found to be static or upward on most of the sampled sites. The recent drought period (1985-92) and the high population of elk in the 1980s and 1990s contributed to the downward trend on some permanent monitoring sites. The use of repeat photography from permanent camera points and the use of permanent line transects for vegetation data acquisition provide the basis on which this comparative study and publication of findings was made possible.
