    Description

    Juniper savanna and pinon-juniper woodland communities collectively represent a widespread and diverse vegetation type that occupies foothill and mesa landforms at middle elevations in semi-arid portions of the American Southwest. Ecological understanding and proper management of these juniper and pinon types requires local knowledge of component species, site history and potential, set within a regional floristic and climatic context. The wide distribution and broad ecological amplitude of this vegetation type across a six-state area of the southwestern United States is best appreciated as the sum of the individual ranges of the component pinon and juniper species, and their environmental tolerances. Key environmental controls of juniper and pinon occurrence, stand age-structure, and composition, include the interaction of climate, topography, soils, and disturbance processes, in combination with biotic interactions, that occur over various spatial and temporal scales.
