Since its establishment in 1970, OCT has acquired ownership of 468 acres of diverse land types, including uplands, wetlands and beachfront. The Trust also holds private conservation restrictions on another 175 acres.
The land that OCT owns is required to be open to the public in order for OCT to remain tax exempt. However, community members are not encouraged to enter every property. Sometimes the topography, wetland features or wildlife significance indicate that it should be left in its natural state.
Property conditions and management activities are overseen by the Trust Administrator, with the help of Trustees and community volunteers. An ongoing, expanding, land stewardship program was created in 2009 to encourage community members to get involved by helping to check for post-storm damage and for property violations, such as debris dumping and encroachment.
