You can print the complete brochure by clicking “complete brochure” on the bottom of the picture to the right.  On the brochure, are links back to the Invasive Species guidelines and to my email if you have any questions.

4. Note that on the Forest Health page, you can find information on some exotic insects and diseases and on the Division of Ecological Resources website you can find info on exotic plants.
