Popis:	Aim Compare contemporary with pre-fire-disruption forest structures, assessing the influence of factors that caused ecological change and evaluating remote sites as relatively natural areas. Location Grand Canyon National Park contains the largest never-harvested and longterm ungrazed forest ecosystem in Arizona, providing valuable sites for measuring natural variability. However, anthropogenic disruption of natural fire regimes since Euro-American settlement c. 1880 has led to changes in forest structure.
