Our Mission

Reef Environmental Education Foundation (REEF) is a grass-roots organization that seeks to conserve marine ecosystems by educating, enlisting and enabling divers and other marine enthusiasts to become active ocean stewards and citizen scientists. REEF programs were initiated in 1993 in Key Largo, Florida, USA. Today, REEF's marine conservation and education programs serve the Tropical Western Atlantic, South Atlantic States, Northeast US & Canada, Pacific Coast, Tropical Eastern Pacific, Hawaiian Islands, and South Pacific. REEF has offices in Key Largo, FL (Headquarters), and field offices in California and Washington State.

Core REEF Projects

REEF was founded in 1990, and in 1993 launched the Volunteer Fish Survey Project. This citizen science fish monitoring program has since become the world's largest such effort. In 2001, REEF initiated two marine conservation research programs. The Grouper Moon Project focuses on mass spawning aggregations of the Nassau Grouper, an endangered Caribbean reef fish. The Invasive Lionfish Program focuses on the invasion of the Indo-Pacific Lionfish into the western Atlantic. REEF's Annual Reports are available online here.
