Island Heritage Trust

What Island Heritage Trust does

Island Heritage Trust (IHT), legally Island Heritage Trust, Inc., is a community-based non-profit land trust incorporated in April 1987 and headquartered at 420 Sunset Road, Deer Isle, Maine. The organization conserves the distinctive natural landscape of Deer Isle, Stonington, and the surrounding outlying islands, stewarding 20+ public preserves, 24,000 acres, and 112 miles of shoreline, including several outer islands (Mark Island, Wreck Island, Round Island, Millet Island) acquired or transferred primarily from The Nature Conservancy in 1997–1999. IHT owns and restores the historic Mark Island Light (Deer Island Thorofare Lighthouse), acquired in 1998, and maintains free public access to all preserves and trails for hiking, kayaking, beach-going, and wildlife observation. There is no proprietary technology product; the operational model centers on land conservation, environmental education, volunteer stewardship, and community events (Wings, Waves & Woods Festival, Quarryography dance series, Concert on the Cove, monthly hiking club, Friends From the Field webinar series co-hosted with Blue Hill Heritage Trust).

IHT serves four overlapping constituencies: year-round and seasonal residents of Deer Isle and Stonington (~3,000 year-round), K–12 students at Deer Isle-Stonington schools (via the Adopt-A-Preserve program, Eco-Club, Marine Studies Pathway, and field trips), regional outdoor recreation visitors, and a broader member/donor/volunteer base. The business model is donation- and membership-supported; all preserve access is free, with no fees, reservations, or service charges. Revenue streams include recurring member contributions, general donations, designated funds (e.g., the Mark Island Lighthouse Restoration Fund), book sales, and event-driven fundraising such as silent auctions and benefit concerts. Capital campaigns have historically mobilized community giving at scale — the 2006 Scott's Landing acquisition raised nearly $1 million from hundreds of donors in partnership with Maine Coast Heritage Trust — and the organization is pursuing formal Land Trust Accreditation Commission accreditation to institutionalize permanence.

The organization operates with a lean staff of approximately 7, led by Executive Director Julia Zell (appointed 2020, previously Development Director from 2019), Stewardship Director David Vandiver, an Environmental Educator, and a volunteer Board of Trustees. Strategic priorities captured in recent governance activity (2026 Bylaws Update, trustee elections, ongoing land acquisitions, and educational hire) point to organizational maturation consistent with its accredited-land-trust trajectory rather than expansion of geographic or programmatic scope.
