New Seed Zones for Bluebunch Wheatgrass Tested
Bluebunch wheatgrass (Pseudoroegneria spicata) is found throughout the western United States and is often used to re-seed burned areas. Bluebunch wheatgrass populations differ in traits important for adaptation to precipitation and temperature. Scientists developed seed zones for bluebunch wheatgrass for the Interior Northwest. Now, a new transplant experiment is underway to investigate the efficacy of these seed zones to ensure establishment and allow for long-term adaptation by maintaining genetic diversity. The results of this reciprocal transplant study will help land managers determine the best sources of bluebunch wheatgrass populations for postfire restoration for a particular area. The study will explore how different populations of bluebunch wheatgrass will adapt to changing climates. Long-term productivity and adaptation will be modeled to allow evaluation of trade-offs between different management options for current and future climates.
