Eleven Year Vegetational Comparison in an Arid Grassland
Proceedings of the American Philosophical Society
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.
