Using a holistic and science-based approach, TNC protects, restores and maintains whole ecosystems, including their bio-diversity, through conservation, re-forestation and tree-planting, the promotion of new national parks, and the use of land preservation techniques such as conservation easements and debt for nature swaps. It has persuaded individuals and organisations to put aside in perpetuity land that is ecologically important as well as encouraged governments to support these efforts.

TNC has a major global presence. It is a model of effective climate remedial action from the ground up.
