NMFS is changing the status of pillar coral (Dendrogyra cylindrus) from threatened to endangered on the Federal List of Threatened and Endangered Species. We have considered the 5-year review of the status of D. cylindrus, expert reviewer comments, and public comments submitted on the proposed rule. Based on this information, we have determined that D. cylindrus is in danger of extinction throughout all or a significant portion of its range. Thus, we are changing the status of D. cylindrus from threatened to endangered under the Endangered Species Act (ESA) of 1973.
