Priority Invasives
WNY PRISM Species Priorities were established in 2015. The Early Detection Priorities were updated, and Watchlist Priorities created, in Fall 2018.
WNY PRISM developed regional priorities through our Terrestrial Working Group and Aquatic Working Group. Working Groups communicate through in-person meetings and email. If you are interested in being part of our Working Groups, please contact Andrea Locke, WNY PRISM Coordinator at [email protected]
