Other Ways to Support

Program, Event or Project Sponsorship

Consider a business or personal sponsorship of our popular Solstice by the Sea or other event. Our Science Squad programs for kids can also be sponsored. Sponsorships are a great way to gain recognition for your business or honor a loved one while supporting FOSI’s work.

Maine’s returnable container law (aka the “Bottle Bill”) means that most people have bottles and cans that must be returned for recycling. If you return your deposit bottles and cans to a CLYNK kiosk, you can designate all or some of your refund to go to FOSI.

It’s easy to do: set up an account at, then load your returnable bottles and cans into a CLYNK bag and drop it off at a designated CLYNK kiosk at a Hannaford supermarket.


If you shop on Amazon, the AmazonSmile program donates 0.5% of the purchase price from your eligible AmazonSmile purchases to a charity of your choice.

Get Involved

Friends of Sears Island (FOSI) depends on active members and volunteers to fulfill its mission of stewardship. Getting involved with our organization is a fun and rewarding experience, and a great way to invest in your community!

To volunteer for any of the tasks below, join our Advisory Group or Board, or discuss a specific skill or area of expertise not listed here, please contact us at We will work to find a good match for you!

Here are some of the many ways you can volunteer:

Help maintain the trails or become an Adopt-a-Trail steward.

Trail maintenance involves trimming back encroaching vegetation and overhanging branches, removing fallen branches, replacing/repairing bog bridges, and installing new signage. You can also adopt a specific trail to visit frequently and report anything that needs fixing to our trail crew.

Lead programs.

FOSI offers a wide range of nature and wellness programs throughout the year. We are always looking for new leaders. Please get in touch if you consider yourself a naturalist, are knowledgeable about a specific topic, or are able to lead an outdoor recreation program, Programs are typically 2 hours in length, and usually take place on the island in warmer months, with the option of indoor workshops or Zoom presentations in the colder months.

Coordinate special events.

Help us organize special events such as fundraising dinners, solstice celebrations, volunteer appreciation gatherings, and occasional on-island programs.

Research grant opportunities and write proposals.

FOSI relies on grant funding to support our projects and operating expenses. We are looking for experienced grant writers to develop proposals and research funding opportunities.


Work with FOSI to plan and implement fundraising programs throughout the year, help organize the annual appeal, work with other organizations/communities to elicit donations, and make presentations to local organizations/towns about Sears Island.


Work with our Outreach Coordinator to plan and supervise educational programs for children and adults. Education volunteers work within local schools and universities to publicize Sears Island, and make presentations to local organizations about Sears Island.

Technical assistance.

FOSI can always use help with graphic design (creating flyers and posters for events), marketing (creating public relations materials and flyers, connecting with local media, sending out press releases, and monitoring digital media), and our online presence (updating and maintaining our website and Facebook page).
