Technical Abstract: There is a great need for biological diversity in reseeding efforts on western rangelands. Legumes provide a crucial component of reseedings, by allowing for higher forage quality, soil nitrogen fixation, pollinator sustenance, and wildlife and wild-fowl feed. In efforts to collect and produce seed of native legumes for revegetation, there is concerns that genetically appropriate sources of legumes be reseeded. The determination of what is genetically appropriate includes evaluatig collections in common gardens, in estimating genetic differences and their relationship to collection-site environments, and in estimating the evolutionary relationship and gene-flow using DNA markers. Each of these methods has inherent strengths and weaknesses, but together they provide some information to assist land managers in determining the best seed sources for their revegetation efforts.
