The Nature Conservancy's mission is to preserve the plants, animals and natural communities that represent the diversity of life on Earth by protecting the lands and waters they need to survive.
We have developed a strategic, science-based planning process, called "Conservation by Design", which helps us identify the highest-priority places, landscapes and seascapes that, if conserved, promise to ensure biodiversity over the long term.
