Abstract
Bromus tectorum invasion is a widespread issue across the Great Basin. Its fire-cycle feedback loops create conditions that native plants cannot withstand, disrupting the ecological balance of the region. Restoration efforts in areas disturbed by B. tectorum have faced challenges in reestablishing pre- fire conditions, but it is possible that, by using native, annual, and locally sourced forbs we may see pre-disturbance communities reemerge. This proposed study aims to assess the potential of the native forb Crypthantha pterocarya’s ability to withstand and combat B. tectorum and assess which conditions in Nevada produce the most capable seeds. Using a competitive common garden experiment, C. pterocarya’s and B. tectorum’s performance will be measured and compared. The performance of Northern and Southern populations of C. pterocarya will also be compared. While recovery of disturbed ecosystems in the Great Basin cannot be achieved solely through native forbs; through this research we will hopefully be able to support the understanding of their ability to set up these ecosystems for successful recovery
