From mauka to makai, The Nature Conservancy works with local communities, businesses and people like you to protect Hawaii's best natural lands and waters. Since 1980, we have established a statewide system of Conservancy preserves, helped create new wildlife refuges and expand national parks, forged partnerships to protect our most important watershed forests and coral reefs, and led efforts to stem the tide of invasive species entering the state. All total, we have helped protect more than 200,000 acres in the Islands.
We invite you to join the effort to preserve Hawaii’s amazing diversity of life. Together, we can help protect the plants and animals that share our world, and nature in turn can help keep alive what is best in our own lives.
