About Us

Who We Are

The Nature Conservancy is a global environmental nonprofit working to create a world where people and nature can thrive.

Founded at its grassroots in the United States in 1951, The Nature Conservancy has grown to become one of the most effective and wide-reaching environmental organizations in the world. Thanks to more than a million members and the dedicated efforts of our diverse staff and more than 400 scientists, we impact conservation in 79 countries and territories across six continents.

Our Challenge Only by working together can we give people hope, keep our wildlife wild and keep our home whole. And ensure the future of a world that sustains us all.

Our Priorities

We are focusing on these key areas in order to achieve our ambitious mission.

Recent Wins

  • The overlook atop Aride Island Special Reserve is at the center of where millions of birds nest during nesting season, Seychelles.

    A Marine Protected Area the Size of Great Britain

    We led a ground-breaking deal that protects nearly 160,000 square miles of ocean off of Seychelles while helping the small island nation pay off its debt and make important climate change adaptations. Explore More

  • Boat drone orthomosaic image of the mapping of Catalina Island, DR (right near Catalinita, all in the Southeast Marine Sanctuary in DR we help protect). Boat drone imagery is one of the 4 layers of data assessment being used for the Caribbean coral mapping project (satellite imagery and aerial hyperspectral sensor imagery are used for mapping and boat drone imagery, and people diving below water are used to corroborate this mapping. the boat and aerial drone data gathering – is completed by TNC. We use it for things unrelated to the CAO work but it will also be combined with the CAO data that is gathered to create the region-wide map of coral reefs across the Caribbean. The goal is that after the Caribbean region is completed, this initiative can be used as a model to help marine regions across the globe map their coral reef ecosystems to better protect and restore them. 
In terms of the ‘bigness’ of the work, Steve Schill (TNC) says we are really the only organization he knows of that is combining these technologies (boat and aerial drone, hyperspectral imaging from CAO plane, Planet satellite) to create coastal habitat maps

    Using Tech to Map Coral Even Better

    We used high-tech planes and satellites to create the highest-ever resolution maps of the Caribbean's coral reefs in order to ensure the protection of these important ecosystems. Explore More
