Inferential Techniques for Soil Depth Determinations. Part I. Coleogyne ramosissima Torr. (Black-Brush).
Abstract
Inferential techniques for soil depth determinations in a high desert environment, Lake Powell, Arizona/Utah, were investigated. The use of vegetation as 'indicator species' to facilitate determinations of soil depth and soil type were examined. Coleogyne ramosissima Torr., commonly called black-brush, has been established as a reliable indicator of the depth of soil to bedrock. Over 375 soil-depth to-bedrock measurements were performed. The soil depths to bedrock within Coleogyne ramosissima communities have a mean of 21 cm with a maximum of 100 cm; the mean of soil depths to bedrock outside Coleogyne ramosissima communities was 120 cm, with a maximum measured depth of 180 cm.
