Successional Trends In An Ungrazed, Arid Grassland Over A Decade, Edgar F. Kleiner
Successional Trends In An Ungrazed, Arid Grassland Over A Decade, Edgar F. Kleiner
Canyonlands Research Bibliography
A study has been made of the vegetational condition of a formerly grazed area, Chesler Park, in Canyonlands National Park. A comparison was made with the same area 10 years earlier. The 10-year successional changes are also compared to baseline data of 10 years earlier from Virginia Park, an adjacent ungrazed area. Because of inaccessibility and long isolation from disturbances, Virginia Park is presumed to be in climax condition and is the control for this study. Chesler Park shows a successional trend after 10 years toward the vegetational condition of Virginia Park. This is exemplified, with only one major exception …

Eleven Year Vegetational Comparison In An Arid Grassland, Edgar F. Kleiner
Canyonlands Research Bibliography
A study has been made of the vegetational condition of two graben valleys in Canyonlands National Park. The sites, formerly subjected to relatively heavy grazing pressure, were originally investigated in 1970 and analyzed again in 1981, providing an eleven-year record of succession. Comparisons are made to successional trends noted in related studies of disturbed and pristine areas. The graben valleys, with few exceptions, show a successional trend over eleven years toward the climax vegetational condition of an area that has never been disturbed.
