AoR 99: 'Defend the Core' Strategy for Invasive Plants, Jeremy Maestas & Dirac Twidwell, Part 1

The Art of Range

Is it time to surrender the Western U.S. to cheatgrass and frequent fire or regroup and work smarter? Jeremy Maestas, NRCS National Sagebrush Ecosystem Specialist, and Dirac Twidwell, range and fire scientist at University of Nebraska-Lincoln, present the Defend the Core framework for invasive species management, a fresh approach that prioritizes preventing degradation where intact, functional plant communities exist and reducing risk of invasives spreading from areas already compromised. After a hundred years of trying to understand invasive plant dynamics, we now recognize that preservationist passive management will not cause degraded plant communities to return to a reference state. This episode, part 1, describes the problem and introduces this new approach to risk reduction. Come back for part 2.
