It isn’t always obvious to the untrained eye whether a natural area is healthy or not. It may appear green and lush, but it may contain non-native invasive species that are prohibiting the native plants from thriving and all the benefits they offer. In the words of the Cook County Forest Preserve,
“Invasive species are one of the most critical problems facing our natural communities and threatening biological diversity. Their impact is second only to habitat destruction or elimination by humans (or their bulldozers). In fact, nearly half the species currently listed under the Endangered Species Act are threatened by invasive species. Invasives can affect the habitat in a number of ways. They compete with other plant species for water and sunlight. They are often inferior in providing food and shelter for native birds and other animals. They decrease diversity and alter the ecosystem dynamics by displacing other plant species. Whenever possible, preventing invasive species from becoming established is the most effective and desired method. Controlling established invasive species is difficult and costly; complete eradication is extremely difficult and rarely possible. Early detection and management can help to avoid permanent species loss that could result from a pest invasion.”
While many Sierra Club members are passionate about these natural areas and desire to work on making them as healthy as possible, we cannot just take this role on. Rather we work under the governance of the Forest Preserve District of Cook County and their volunteer program. This excellent and well-run program offers volunteers many opportunities to contribute, learn, and lead.
Please visit their Volunteer website to learn more and feel free to contact Sierra Club member and steward at Deer Grove Forest Preserve Sue Gorr with questions. Volunteer opportunities are year-round and at most forest preserves. These events are listed at the website. Also training classes are available for the more serious volunteers who wish to lead workdays, handle special equipment, perform special functions, and more.
