The Nature Conservancy


We work in all 50 states and 32 countries — protecting habitats from grasslands to coral reefs, from Australia to Alaska to Zambia. We address threats to conservation involving climate change, fire, fresh water, forests, invasive species and marine ecosystems. We've protected more than 119 million acres of land and 5,000 miles of rivers worldwide — and we operate more than 100 marine conservation projects globally.

It's how we work that has made the Conservancy so successful — and makes us optimistic that we can expand that great conservation work to meet the challenges ahead: We use a science-based approach — aided by our more than 700 staff scientists. We pursue non-confrontational, pragmatic solutions to conservation challenges. We partner — with indigenous communities, businesses, governments, multilateral institutions, other non-profits…and people such as yourself.
