The Illinois Clean Energy Community Foundation has offered TWI a $21,000 grant for the Sandy Hollow restoration at the Dixon Waterfowl Refuge if we can raise $7,000 in new donations for the project by May 31. That means your gift to restore rare sand habitats will go four times as far!

No matter your experience level, there will be ways for you to be part of this event.
