Summary

We used Rangeland Condition Monitoring Assessment and Projection (RCMAP) maps of annual herbaceous fractional components (mostly invasive annual grasses) to calculate mean rate of change in invasive annual grass cover over five-year time periods (ratesOfChange1987_2021.zip). We also created a map that identifies zones of the sagebrush biome that could be prioritized for different management goals (managementOpportunities.zip). The invasion of annual grasses has altered fire regimes and has contributed to the decline of sagebrush ecosystems. The vast expanse of annual grass invasions has required land managers to prioritize treatments in locations where they expect to be able to make a meaningful impact on invasion outcomes. Maps of [...]

Purpose

These data were created to assess the rate of change or trajectory of invasive annual grasses across the sagebrush biome of the western United States. This information can be used to understand the historical trajectories of invasive annual grasses and how trajectories of invasion can inform potential management options. Rates of change in invasive annual grass cover are often best understood in context of the raw invasive annual grass cover, as we have done in our summary management opportunity map.
