A geographic strategy for cross-jurisdictional, proactive management of invasive annual grasses in Oregon

•Invasive annual grasses pose a widespread threat to western rangelands, and a strategic and proactive approach is needed to tackle this problem.•Oregon partners used new spatial data to develop a geographic strategy for management of invasive annual grasses at landscape scales across jurisdictional boundaries. The geographic strategy considers annual and perennial herbaceous cover along with site resilience and resistance in categorizing areas into intact core, transitioning, and degraded areas.•The geographic strategy provides 1) a conceptual framework for proactive management, building upon similar work recently begun across the Great Basin, and 2) multi-scale spatial products for both policymakers and local managers to identify strategic areas for investment of limited resources.•These spatial products can be used by Oregon partners to generate a shared vision of success, facilitate proactive management to “defend and grow the core,” and collaboratively develop meaningful and realistic goals and strategies for management of annual grasses at landscape scales.
