The Conservancy also operates the Stop the Spread program, a partnership between the Conservancy's naturalists, CHIRP staff and the many youth camps on the Island. The program is focused on invasive plant control in and around each camp. It is an opportunity for campers to learn about the value of native species, the problems posed by invasive species and how to help eradicate invasive species. The campers also learn how to restore and improve native environments. Stop the Spread has given nearly 15,000 campers tens of thousands of hours of education from 2009-2013. Campers manage about 450 acres for 75 different invasive species, logging more than 7,000 hours of invasive plant removal a year.
