We depend upon membership dues, grants, and donations to provide the funds to:
- Make visits to the islands possible
- Restore and maintain the historic structures, including three lighthouses, three keeper houses, a tramway and a whistle house
- Improve and maintain the scenic trails, picnic and camping areas
- Plant native species to encourage more birds, bees, and butterflies
- Preserve the islands' unique historic and natural attributes
In addition, many TIA members provide volunteer labor to assist the Town Committee in its mission to manage and maintain the islands.
