Science in the Preserves

We are serious about our goal to eradicate the non-native invasive species, buckthorn, from our forest preserves and beyond. In 2015, we convened several regional organizations to discuss ideas for controlling buckthorn. This conversation was organized to launch a pilot project to improve landscapes within the vicinity of Middlefork Savanna.

Around that same time, we forged a partnership with social scientists at the U.S. Forest Service (USFS). Eager to discuss applicable methods for behavioral change and conservation psychology, we teamed up with researchers at the USFS to determine people’s perceptions of the trees and aesthetics in the buck­thorn pilot area.

We distributed a homeowner survey to research the best ways to eradicate buckthorn and support native landscapes. All residents within the pilot project area received the same questionnaire. The survey consisted of multiple choice and open-ended questions, following a format based on the Theory of Planned Behavior, a well-accepted way of predicting people’s intentions to act on a given issue. These important predictors have been successfully used in many studies of land manage­ment. Related questions about people’s activities and values regarding yards, landscaping, and the environment will help us better understand their willingness to take action.

Over six months, we compiled and analyzed responses. Participation and responses to this survey was used to enhance outreach efforts, focus restoration activities, and inform similar projects throughout the region. Homeowners who participated in the survey received a report of results and the first invitations to join us in this effort to build a more resilient future for Lake County.

Buckthorn Homeowner Survey Results

Several homeowners have already volunteered to join the movement to eradicate buckthorn. Whether they have removed buckthorn from their yard or are simply considering it, every resident who participates will benefit the community. Below is a full copy of the results that survey participants received from us in July 2018. Flip through the report below or read it here to learn more.
