The Nature Conservancy is the leading conservation organization working around the world to protect ecologically important lands and waters for nature and people.

We address the most pressing conservation threats at the largest scale. Thanks to the support of our more than 1 million members, we’ve built a tremendous record of success since our founding in 1951:

• We’ve protected more than 119 million acres of land and thousands of miles of riversworldwide — and we operate more than 100 marine conservation projects globally.
• We are impacting conservation in 72 countries — protecting habitats from grasslands to coral reefs, from Australia to Alaska to Zambia. See where we work.
• We address threats to conservation involving climate change, access to clean water, ocean health, and everything in between. Learn how we’re responding.
