Genetic Considerations for Grassland Restoration in Oregon's Willamette Valley

Principles of population genetics should be considered when planning a grassland restoration, but compromise is usually necessary. First, we use these principles to determine what species and seed sources are most desirable, often making those choices despite lack of knowledge about population genetics of individual species. Second, we may compromise to match our desires to real limits of funding, time, and seed availability. Third, we review the plan to assure that it will not harm local stands of native plants and local genetic diversity. Lastly, we finalize the plan, realizing that if we cannot implement an acceptable restoration plan, exotic grasses will grow on the site and competitively exclude native Willamette Valley species.
