This handbook may help livestock producers reduce tall larkspur poisoning in cattle by providing information on: (1) identifying tall larkspurs, (2) treating poisoned animals, (3) collecting larkspur samples to determine toxicity, (4) understanding toxic alkaloid concentrations in tall larkspur, and (5) determining the relative risk of grazing tall larkspur rangelands. Armed with this information and working with extension agents and local veterinarians, livestock producers can make informed decisions about grazing tall larkspur-infested areas to reduce cattle losses. This information must be adapted for each ranching situation. Livestock producers must be aware of annual variations in growth and toxicity of tall larkspur and be flexible in implementing any grazing management strategy.
Articles, citations, reports, websites, and multimedia resources focused on rangeland ecology, management, restoration, and other issues on American rangelands.
