Make a Difference in New Hampshire

The mission of The Nature Conservancy is to conserve the lands and waters on which all life depends. Since 1961, we've been working in New Hampshire to do just that. Together with partners, local landowners and the support of members like you, we have helped to protect nearly 300,000 acres and 680 miles of rivers and streams in the Granite State.
