Download the new Pasture Bullies handout on toxic plants.

“Pasture Bullies” are plants that are toxic to horses and livestock. These toxic plants include invasive weeds and non-pasture plants that can seriously harm or kill your animals.

Clackamas Soil and Water Conservation District has a new handout that provides information on many of these “Pasture Bullies.” Learn how to identify toxic plants in or around your pasture or in imported hay. You can download the handout below for easy reference!

The danger of these toxic plants is dependent on the quantity consumed by your animals. The handout does not list every plant that might be toxic to horses or livestock. Instead, the list focuses on plants that are commonly found in Western Oregon.

If you have an animal that you believe has been poisoned, contact a veterinarian immediately.

Tips to Avoid Plant Toxicity

You can avoid plant toxicity by creating an environment where toxic plants are not able to thrive and spread. One way to do this is to reduce and control weeds. Consider developing a land management system using Integrated Pest Management (IPM).

Part of IPM is managing pastures for healthy soil and high-quality forage. Invasive weeds have a hard time competing with vigorous, healthy plants.

  • Allow grasses to recover after grazing. Never graze below 3” before moving animals to another pasture paddock.
  • Divide your land into smaller paddocks and rotate your animals together through each area. This allows other areas to rest and regrow.
  • Create a sacrifice area for use during the rainy season. This protects soil and grasses from hooves that are very destructive on wet pastures.
  • Test your soil. Then add manure, lime, or fertilizer to improve soil fertility as recommended by test results.
