Unknown and unprotected the imperiled genetic resource of native plant populations on roadsides and private lands

Abstract

The Willamette Valley has lost almost 99% of its native prairie habitat. The most vulnerable populations of native plants are on roadsides and unprotected private lands. Collection of seed from these populations is therefore imperative, not only to ensure these genetics are not lost but to develop a supply of genetically diverse native plant material for restoration of prairie ecosystems in the Willamette Valley. Although debate continues among restoration professionals as to the appropriateness of mixing seed sources, acceptance is growing in the Valley that this is desirable within an ecoregion. The hope is that diverse, established populations for restoration will have a better chance of survival over the long term.
