The Nature Conservancy is the leading conservation organization working around the world to protect ecologically important lands and waters for nature and people. In Massachusetts, we have protected some 23,000 acres of crucial natural resources, and we lead science-based projects to keep nature healthy throughout the state.
Committed to solving the most urgent challenges facing people on Earth, we pioneer on-the ground and in-the-water approaches to protect and sustainably manage natural systems. From there, we bring proven solutions to scale through regional and global networks of conservation specialists.
From preserved lands to sustainable fishing, from clean water to healthy forests, from policy work to community volunteerism, we proudly represent the ideals of 28,000 members in Massachusetts and more than one million members globally.
Since our founding in 1951 The Nature Conservancy has 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. We work in all 50 states and more than 30 countries — protecting habitats from grasslands to coral reefs, from Alaska to Zambia.
Now we are pursuing an ambitious vision to create a vibrant network of healthy natural and human communities across Massachusetts and around the world.
