Poisonous Rangeland Plants in San Luis Obispo County is a comprehensive educational guide to rangeland plants that are toxic to domestic livestock. This guide begins with an exploration of how the biological systems are affected by the poisonous plant toxins. The biochemistry behind these toxins is included in the discussion. Next, reference material for fourteen plants that inhabit San Luis Obispo County is provided. This information includes specific toxins found in poisonous plants, affected animals, symptoms of poisoning, stages of growth, lethal dose, and distribution of the plant in California. This section of the guide is filled with helpful photos of the plants at different stages of growth. The remaining portion of the guide is dedicated to general management strategies to prevent the effects of poisonous plants as well as specific strategies for the fourteen plants. A quick reference page for both the fourteen poisonous plants and management techniques are included in the reference for quick access.
