Abstract:

Pinyon-juniper and juniper woodland vegetation occurs at the northern extent of its range in Idaho. In a nationwide study, Idaho-endemic woodland communities are recognized as both the most rare and most poorly understood. To assist with their identification and description, and assessment of their conservation status, pinyon- and juniper-dominated woodland communities were sampled in Bureau of Land Management and National Forest System ecological reference areas. Pinyon-juniper vegetation observed at 12 Research Natural Areas and associated sites within southeastern Idaho is classified on the basis of perceived natural potential. Four series are recognized: singleleaf pinyon (Pinus monophylla), Rocky Mountain juniper (Juniperus scopulorum), Utah juniper (Juniperus osteosperma), and curlleaf mountain-mahogany (Cercocarpus ledifolius) on the basis of potential for dominance and relative tolerance of environmental stress. Twenty-three plant associations are identified. Community composition, distribution, and environmental relations are summarized. This information on stand composition and structure provides a baseline for conservation planning and ecosystem management.
