This presentation aired as part of the Great Basin LCC webinar series on November 29, 2017. The presentation was given by Bruce Roundy of Brigham Young University.In this webinar, Dr. Bruce Roundy of Brigham Young University discusses climatic conditions that favor cheatgrass and those that favor desirable perennial herbs. He explains why conditions that favor cheatgrass are associated with less resistance and those that favor perennial herbs are associated with more resilience. The presentation suggests ways to increase resistance to weeds and system resilience when planning fuel control treatments in sagebrush steppe.

FY2014Avoiding cheatgrass dominance following tree-reduction treatments on woodland-encroached sagebrush communities is a priority for managers in the Great Basin. Perennial herbaceous and weedy annual cover have been related to site resilience after treatment and associated with soil climate regimes and site physical characteristics. Additional investigation of site characteristics associated with vegetation response will allow us to better decide which sites to treat and whether seeding is needed or not in conjunction with tree reduction treatments. Site-level planning also requires an understanding of how climate change may influence vegetation response to treatments. We propose to associate site-measured soil...
