Poisonous Plant List
Many common plants are toxic, and keepers must make sure that their herbivorous chelonians are kept away from them. A simple step to take to minimize the risks to your turtles and tortoises is to learn the names of all the plants in your home and yard so that you can prevent any untoward contact with poisonous plants. If you are unable to identify specific plants, your local nursery may be able to identify them for you. Be sure to note the correct spellings of both the common and the botanical names, and keep a list of the names for future use. If you do take plants to your nursery for identification, be sure to take a sufficient sample that represents the plant as a whole. |
The following list is based on CTTC's poison plant list as published in the Tortuga Gazette 28(1): 8-10, January 1992 with periodic updates as more data becomes available. The list itself was based on the University of California Irvine, Regional Poison Center list of plants that are toxic or potentially toxic to humans. They recognize four levels of toxicity, indicated by a number following the plant name, and the four levels are explained at the end of the article. Note that the treatments recommended are for humans. Use your own best judgment in applying them to your pets. Initially, be sure to remove any remaining parts of the plant from the mouth. If any symptoms of abnormal behavior or signs of irritation in the mouth occur, seek prompt medical attention. |
