Our Mission
The mission of The Nature Conservancy is to protect the land and water on which all life depends, and for nearly three decades, we’ve been working across the 28-million-acre Greater Yellowstone ecosystem to do just that.

Program Overview
Protecting Clean Water
The Greater Yellowstone is the source of seven major rivers and an average of 4 trillion gallons of freshwater, which helps “water the West” so that people and nature thrive.
