Successful experimental elkhorn coral colony in Dry Tortugas National Park

Detailed Description

The U.S. Geological Survey is conducting research to guide the restoration and recovery of threatened corals in Dry Tortugas National Park and throughout the western Atlantic. Shown here is a colony of the threatened elkhorn coral, Acropora palmata, that has grown over the sides of a cinderblock experimental platform. Behind the elkhorn in the background is a wild, healthy stand of another threatened species--the staghorn coral, Acropora cervicornis. USGS scientists are studying coral-growth, or calcification, rates throughout the Florida Keys to understand why some corals thrive in certain areas, and thereby help guide reef-wide restoration strategies.
