The Toxic Plant Database was developed by a team of Professors working through Texas Cooperative Extension, a division of the Texas A&M University System. Although the database focuses on toxic plants in Texas, many of the plants are found in other states as well as Mexico. This is a well-organized website containing pictures, maps, plant descriptions, information on the toxic agent, symptoms of poisoning, habitat, distribution, and "Integrated Toxic Plant Management for each toxic plant." Site users may search this extensive listing of Toxic Plants by the following categories: Common or Scientific Name, Region, Symptom, Livestock, or Plant Images. This site also links to a glossary of relevant terms.
