Explore the Island: Learning and Recreation



Sears Island is an excellent outdoor classroom for learners of all ages. Each summer FOSI hosts a series of guided nature walks and natural history seminars which are free and open to all. These programs cover a wide range of topics, including marine biology, geology, wildflower identification, photographing butterflies and other insects, medicinal plants, yoga class on the beach, mushroom identification, and more. Families are always welcome, and FOSI offers environmental education programs designed specifically for children and their parents from time to time. These events, which are typically offered May through September, are publicized on our FOSI News Blog, on our Facebook page, and in local newspapers.

Friends of Sears Island has also worked to encourage local schools to utilize the island as a living lab. In 2015, we collaborated with Searsport District High School to offer a class to students called “Sears Island: Issues and Possibilities.”  With special permission, scientific research is occasionally carried out on the island, and FOSI is always looking for volunteers to help us with our new citizen science monitoring project. This is an effort to engage island visitors in helping to monitor what they see. With many eyes on the ground reporting observations of plants, wildlife, and more, we can get a clearer picture of the diversity of species on the island, as well as where to focus our efforts for invasive species removal. Visit our Explore the Island page  to learn more about our Citizen Science Initiative or contact Aleta at greenwayscenter@gmail.com to find out how you can get involved.

FOSI is always looking for people who are willing to share their time and talents, whether by leading a program in your area of expertise, helping out with scientific monitoring and invasive plant removal efforts, trail maintenance, pitching in with administrative tasks, attending a board meeting, or financially supporting the efforts of our organization.  Check out our Volunteer page and Donate page if you are interested.

Lastly, FOSI has a PowerPoint presentation about the history of the island and the organization. We are happy to give presentations and talks to local organizations and school groups in an effort to educate others about Sears Island. Contact us for more information.
