Pinyon-juniper (PJ) woodlands are among the most extensive and rapidly changing ecosystems in the West. Increasing wildfire activity, invasive species, insect outbreaks, changing climate and drought conditions, and expanding human pressures are creating new management challenges across PJ woodlands.

The Pinyon-Juniper Mapping Project is developing consistent, west-wide information to help resource managers prioritize actions, evaluate opportunities and constraints, and strategically invest limited resources to actively manage these landscapes. These products are intended to support fuels reduction, woodland restoration, wildlife habitat enhancement, watershed resilience, and community wildfire protection while maintaining the ecological, cultural, and economic values of pinyon-juniper landscapes.

Pinyon-juniper woodlands are among the most extensive and rapidly changing ecosystems in the West. Climate change, altered disturbance regimes, invasive species, insects, and expanding human pressures are creating new management challenges across the biome.

The Pinyon-Juniper Mapping Project is developing consistent, biome-scale information to help managers prioritize actions, evaluate opportunities and constraints, and strategically invest limited resources. These products are intended to support fuels reduction, woodland restoration, wildlife habitat enhancement, watershed resilience, and community wildfire protection while maintaining the ecological, cultural, and economic values of pinyon-juniper landscapes.
