The New Jersey Natural Lands Trust preserves land in its natural state for enjoyment by the public and to protect natural diversity through the acquisition of open space. The Trust manages its properties to conserve elements of natural diversity, such as habitat for rare plant and animal species and rare ecological communities.

The Trust invites passive use by the public for recreational or educational purposes wherever such use will not adversely affect elements of natural diversity.

Currently the Trust owns or manages over 25,000 acres of open space from Sussex to Cape May Counties, including over 2,500 acres of conservation easements.
