This database of photos was started by Animal Science faculty and staff at Cornell University as a public service. Some of the information has been put together by students in the Animal Science 625 course. Please let us know if you find any errors or misidentifications and we will get them corrected as soon as possible.

IMPORTANT: This database of poisonous plants is correct to the best of our knowledge. However, just because a plant is NOT listed does not mean that it is NOT poisionous to a certain species. A good rule of thumb: if you have any doubt about a plant, assume it is poisonous!
