Restoration work at
Swallow Cliff Woods

Palos, Illinois
This is a beautiful native trillium we found on
one of our Spring field trips. While we were
there, we also checked the woods for non-
native weeds called garlic mustard. Garlic
mustard was brought from Europe by early
settlers and escaped into the wild. Since each
mustard plant produces thousands of seeds
each Spring, it is slowly taking over the
habitats that would normally support native
woodland plants. Part of our Spring work at
Swallow Cliff Woods is pulling out every garlic
mustard plant we can find.

On Winter field trips, we cut out non-
native brush that is taking over the oak
woods
One of our ace winter clean-up crews!
