We partner with local stewards and scientists to bring living coastlines back to life.

Volunteers restoring a mangrove wetland

Our Mission

EarthTide Alliance is dedicated to restoring the world's coastal ecosystems by funding mangrove replanting, wetland protection, and coral reef recovery in the most threatened regions.

Since 2014, we have grown from a volunteer diving club into a global coalition of more than 30,000 supporters across 85 countries, delivering 400+ shoreline restoration projects.

Every program pairs on-the-ground fieldwork with long-term monitoring, so the ecosystems we save are measured, verified, and kept alive for decades to come.
