This was a great opportunity to learn about trees and the natural history of Petrie Island! Tree experts provided instruction to the volunteers on how to take measurements and helped with tree identification. The location of invasive species was also documented.

This year focused on trees in the middle of the island, which is known for its Hackberrys and tree diversity. Please see the current listing under the Nature section of this website. http://www.petrieisland.org/plants-and-flowers-of-petrie-island
