Two of the predominant interests in ecology are patterns in the distributions and abundances of organisms and the interrelationships of organisms with their environment. Many naturally occurring phenomena take on self-similar distributions, appearing the same over different spatial scales. I tested to see if sagebrush, Artemisia tridentata, was self-similarly distributed and whether three abiotic factors - slope, aspect and soil moisture, are themselves self-similarly distributed and correlated with the presence or absence of the sagebrush at three sites in the East River Valley, Gunnison County, Colorado. At one of the site there was a significant difference in soil moistures between sites with sagebrush present and those without, and at another site aspect appeared to have a significant impact on the presence of sagebrush. The power law exponent, y’, related to the fractal box counting dimension, of the abiotic factors were the same as the y’ values for the distribution of sagebrush at each site. Semivariogram analysis also indicated a self similar distribution of many of the abiotic factors. It is unclear why the y’ values of the abiotic factors would be related so closely to those of the sagebrush.
