The Staghorn coral is a critical endangered coral with cylindrical branches found throughout the Florida Keys, the Bahamas, the Caribbean islands and the Great Barrier Reef. Coral reefs are endangered by a variety of factors like natural phenomena such as hurricanes and diseases, local threats such as overfishing, destructive fishing techniques, coastal development, pollution, and careless tourism and the global effects of climate change—warming seas and increasing levels of CO2 in the water.

Threats:
Diseases
Temperature extremes
Storms and flooding
Pollution by domestic & urban waste water
Tourism

Conservation actions:
Water protection in Marine Sanctuary
Further research is needed into disease etiology, and effectiveness of current restoration methods.
