The remnant Illinois populations were less genetically diverse than the restored Illinois populations and the Kansas population. These restored Illinois populations were established with at least two seed sources that were locally collected. There was little population divergence ( ), which is consistent with other perennial forbs, while the genetic relationships among populations reflected geographic proximity. In a greenhouse competition experiment, differences in performance between seedlings was not related to the remnant or restored status of Illinois populations, but plants from Kansas were significantly smaller than Illinois plants. Genetic diversity and competitive ability were not associated with the size of the original source population. Our data indicate that using multiple local seed sources for restoration projects will maintain the local gene pool while enhancing the regional genetic diversity of this species.10aconservation genetics10alocal seed source10arestoration ecology10atallgrass prairie1 aGustafson, D.J.1 aGibson, D.J.1 aNickert, D.L.  uhttp://knz.lternet.edu/content/genetic-diversity-and-competitive-abilities-dalea-purpurea-fabaceae-remnant-and-restored
