Death camas contains toxic steroidal alkaloids that occur throughout the plant; plants are dangerous at all times. Black nightshade is an introduced herbaceous annual weed that can be found growing mostly on disturbed soils and waste areas in the eastern U.S. and into the Midwest. Because of its attractive flowers, poison hemlock was brought to the U.S. from Europe as a garden plant but has escaped cultivation and can be found growing in many pastures and in some areas on rangeland. In Holt McDougal, 1976. Namely the small pollinators, such as sweat bees and pollinating flies who visit the flowers for nectar as well as the birds who eat the ripe berries.

Supplemental feeding is beneficial, especially when animals are trailed through lupine ranges. I hope to give you some tips and useful information! Cattle should be moved off of the larkspur areas during the flower stage but can graze larkspur in the late pod stage when toxicity declines. However, one should avoid contact with sap, roots, or berries. Pokeweed seeds will germinate best in disturbed soil. I mentioned that Pokeweed is aggressive.
