Technical Abstract: Native legumes grow in many rangeland and woodland communities in North America. Many are valuable as food and habitat for wildlife, forage for livestock, and nitrogen fixation through a symbiotic relationship with bacteria, but some are toxic and others invasive. Evaluation and release of germplasm and cultivars for use by wildlife and livestock have occurred for several genera, but many others have not been included in these selection programs. Genera receiving the most attention include the following: Cassia/Chaemacrista (Southeastern USA), Desmanthus (Central and Southern USA), Desmodium (Southeastern USA), Hedysarum (Western USA), Lespedeza (Cental and Southeastern USA), Lupinus (Eastern and Western USA), Mimosa (Southeastern USA), Petalostemum/Dalea (Central and Western USA), and Strophostyles (Southeastern USA). I will describe geographic and ecological distributions of important forage, toxic, and invasive legume species in the United States.
