Land Acquisition and Conservation Easements 2 activities
- Accept land and conservation-focused estate giftsAccepts donations of land, retaining them in perpetuity in their natural state without selling or trading, and accepts estate planning gifts to support endowment and stewardship objectives. Received 73 acres of woodland through bequest from Alice Coffin in 1963 for use as a wildlife sanctuary.
- Maintain and manage wildlife preservesOwns and manages 13 properties, including 11 wildlife preserves in the Mill Neck and Lattingtown areas of Long Island, acquired since 1963 through community donations of land and capital. These include diverse habitats such as wet woodlands, salt marshes, open meadows, and mature forests, which are preserved in their natural state for scientific, educational, and aesthetic purposes.

-
Nature Preserve Management and Public Access 1 activity
- Provide public access to nature preservesOperates two publicly accessible preserves—Shu Swamp and Coffin Woods—with daily access from dawn to dusk, closed on Fridays; nine other preserves require appointment with the Warden for entry. Maintains hiking trails through oak, hickory, hemlock, and beech forests for public use and nature observation.
-
-
Wildlife Monitoring and Field Research 1 activity
- Publish ecological documentation and species inventoriesMakes available downloadable plant lists documenting species found in Shu Swamp and maintains a documented plant species list for Coffin Woods preserve, supporting scientific and educational use of the sanctuaries.
-
-
Artificial Nesting Habitat Management 1 activity
- Support native species and wildlife habitat restorationManages ecosystems to support native plant and animal species, including reintroducing ospreys via a nesting pole installed in 1984, resulting in the rearing of 33 young birds; supports populations of rare species such as American Brook Lamprey, tri-colored bats, Strawberry Bush (Euonymus americanus), and provides roosting and foraging habitat for birds including ospreys, bald eagles, herons, egrets, kingfishers, and waterfowl.

How they approach the work
Named approaches extracted from this org’s sources. Where others share an approach, follow it to see the full set of orgs running it.
- Conservation Through Environmental Education and Public Reconnection with Naturemethodology: conservation-through-educationBy combining land preservation with environmental education and low-impact public access, the organization fosters public stewardship of natural areas, because direct experience with nature strengthens conservation values and community engagement.
- Habitat Restoration with Targeted Interventions for Species Recoverymethodology: habitat-restoration-with-artificial-nesting-structuresBy using artificial nesting structures and protecting geographically sheltered habitats, the organization enables the recovery of specific species like osprey, because targeted restoration compensates for lost breeding sites and enhances ecosystem resilience.
- Land Preservation and Habitat Conservation through Perpetual Protectionmethodology: perpetual_land_preservationBy preserving land in its natural state in perpetuity, particularly through donated properties, the organization protects critical habitats and supports biodiversity, because permanent protection prevents development and ecological degradation.
- Low-Impact Access and Controlled Visitations to Protect Habitat Integritymethodology: controlled_access_managementBy restricting public access through appointment-only visitation, designated trails, and rules against disruptive activities, the organization minimizes human disturbance to sensitive ecosystems, because controlled access preserves wildlife behavior and habitat function.
- Wildlife Health Monitoring as an Indicator of Ecosystem Resiliencemethodology: wildlife_health_monitoringBy monitoring the health of vulnerable wildlife species, the organization assesses broader ecosystem health, because disease patterns in indicator species reveal environmental stressors and inform adaptive management.
