Developing a Decision Support Framework for Prioritizing Pinyon Juniper Forest Treatments on the Colorado Plateau

Across the western U.S., pinyon and juniper trees are expanding into sagebrush and grassland plant communities. This vegetation change has been perceived to have a significant impact on the economic value of these grasslands, which support activities such as livestock grazing and hunting, but expanding pinyon and juniper forests may also lead to increased risk of fire. Over the past several decades pinyon-juniper forests have been removed across large areas of land to improve wildlife habitat and grazing land productivity while reducing risks of wildland fire. What isn’t known is whether these strategies are effective in reaching this goal, especially given that our future climate will likely be hotter and drier across many regions of the western U.S.



This project will develop a tool that can inform management decisions on where, when, and how to prioritize pinyon-juniper treatments under a future climate that is likely to be hotter and drier. This work will be conducted primarily on the Colorado Plateau, in the states of Colorado, Utah, and Arizona. The study aims to support collaboration between resource managers and researchers to create a support tool for planning, implementing, and evaluating pinyon-juniper treatments. The research team will then guide a broader community of stakeholders in using this tool in planning future pinyon-juniper treatments under changing climate conditions.
