Join scientists and other experts in a 24-hour search for the plants and animals that call the St. Croix River Valley home. The St. Croix Bioblitz will be held May 20 – 21, 2016 at the St. Croix National Scenic Riverway, Minnesota Interstate State Park, and Wisconsin Interstate State Park.

So what is a Bioblitz? Biologists lead an intensive survey to count as many species as possible in a particular area within a set time frame. This “snapshot” of information helps scientists and park managers understand the river and the surrounding environment and what species make the St. Croix Valley their home.

The public is invited to join this quest to discover and document biodiversity by participating in over 40 activities, including surveys and presentations. The St. Croix Bioblitz will include experts on plants, mammals, birds, mussels, amphibians, fish, insects, and many other animals, including those active at night. There will be a variety of opportunities to assist in catching and identifying species.
