Great Lakes BioBlitz

media release: Runs for four weeks, starting Earth Day (Wed. April 22nd), ending Sat. May 23rd.

This free event focuses on finding and identifying as many wild, living things as possible in the Canadian provinces and the U.S. states that have coastline on the Great Lakes during a specified period of time. You need not be in the Great Lakes basin watershed to participate, just in a Great Lakes state or province – which is why all of Wisconsin is included! The beauty of this project is that you decide your level of participation! Take an afternoon to explore and document some plants or wildlife in an area, or pick a location to return to weekly, or set a goal to find something new every day–there are many ways to participate.
