Coral Restoration Foundation™ (CRF) is the world’s largest non-profit marine-conservation organization dedicated to restoring coral reefs to a healthy state, in Florida as well as globally. Headquartered in the Florida Keys, CRF was incorporated in 2007 in response to the widespread loss of the dominant coral species on Florida's Coral Reef. CRF’s core mission is to restore coral reefs, to educate others on the importance of our oceans, and to use science to further coral research and coral-reef monitoring techniques. Coral reefs are the most threatened habitat on earth and stony corals the most at risk group of animals facing extinction. All coral reefs, in all oceans of the world, are at risk. Since 2012, CRF has planted more than 250,000 critically endangered staghorn, elkhorn, and star corals back onto these reefs, an ambitious scope of work carried out by a small team of staff, countless volunteers , and interns. Large-scale and massive action is required to save our reefs. CRF has proven that this is possible after more than a decade of successfully outplanting corals throughout the Florida Keys.
