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 (lockeas@buffalostate.edu).
