Plants Poisonous to Livestock in the Western States
USDA Agricultural Research Service, Poisonous Plant Research Laboratory (Logan, UT)
Illustrated federal reference covering the major toxic range plants (larkspur, locoweed, lupine, hemlocks, death camas, nightshades...): identification photos, toxic principle, signs of poisoning, and management. Serves both the poisonous-plant and livestock-basics briefs with a clean license and redistributable IMAGES.
Editor's notes
Framed around livestock, not human ingestion — pair with human-focused warnings. Western-states scope; eastern poisonous plants need coverage from the FM 3-05.70 appendix and FDA material.
