RT Journal Article SR Electronic T1 Unknown and unprotected the imperiled genetic resource of native plant populations on roadsides and private lands JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 276 OP 284 DO 10.3368/npj.12.3.276 VO 12 IS 3 A1 Boyer, Lynda YR 2011 UL http://npj.uwpress.org/content/12/3/276.abstract AB 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.
