USDA-ARS Poisonous Plant Research Laboratory: History and Current Research on Western North American Rangelands

On the Ground
- Poisonous plants on western North American rangelands have historically been troublesome to livestock producers.
- Research on toxic plants was initiated by the United States Department of Agriculture in the late 1890s to solve problems for the livestock industry.
- The United States Department of Agriculture Agricultural Resource Service Poisonous Plant Research Laboratory in Logan, Utah continues to provide research-based solutions to poisonous plant problems besetting livestock producers, hobby farmers and small holders, veterinarians, and extension personnel.
- Principal plants of current research interest include larkspur, lupine, locoweed, selenium accumulating plants, pyrrolizidine alkaloid-containing plants, and ponderosa pine.
