That is, mountain ranges were randomly selected, but stands were systematically located on mountain ranges. The National Hierarchical Framework of Ecological Units (ECOMAP) was used for the highest levels of classification, subdividing the Great Basin into nine relatively environmentally homogeneous Sections. The remaining levels are vegetation-based, focusing on the relative composition and dominance of pinyon and juniper and the dominant shrub and perennial grass species present. This approach will allow managers to better relate the results of previous, as well as new studies and management experiences.
