Celebrate Earth Day by making a visit to Monee Reservoir and help keep the preserve free of trash. Fishing line, as well as other debris, poses serious threats to wildlife. Animals often become entangled in fishing line, or can swallow hooks or bits of plastic. Stop by the concessions window, pick up a trash bag and gloves, and fill the bag with any trash you collect. Bring the bag back to the concessions window and receive a free gift. Sidewalks are easily accessible; trails are on natural, uneven terrain.
