During the 20th Century, the Grinnell, Goodspeed, and Wickson Natural Areas on campus became heavily invaded with ivy and other non-native vegetation that suppressed the biodiversity that once existed within the riparian zone of Strawberry Creek. Thanks to many student and community volunteers in the past 20 years, some of the natural areas are relatively weed-free and can support native vegetation. This work is ongoing - join us for an event!
