Pillar coral is a hard coral found in the western Atlantic Ocean and the Caribbean Sea. It often resembles fingers or a cluster of cigars, growing up from the sea floor. Pillar coral is listed as endangered under the Endangered Species Act.

NOAA Fisheries is committed to conserving and protecting pillar coral. Our scientists and partners use a variety of innovative techniques to study, learn more about, and protect this species.

Where They Live

Pillar coral can be found in the Caribbean Sea, Gulf of America (formerly Gulf of Mexico), and southern Atlantic (southern Florida).

Management Overview

The pillar coral is listed as endangered under the Endangered Species Act.  

Additionally, the pillar coral is listed under:

  • Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) 
  • Annex III of the Protocol for Specially Protected Areas and Wildlife (SPAW)

Recovery Planning and Implementation

The Recovery Outline is meant to serve as an interim guidance document to direct recovery efforts, including recovery planning, for pillar coral, rough cactus coral, lobed star coral, mountainous star coral, and boulder star coral.

Critical Habitat Designation

Once a species is listed under the ESA, NOAA Fisheries evaluates and identifies whether any areas meet the definition of critical habitat. Those areas may be designated as critical habitat through a rule making process. The designation of an area as critical habitat does not create a closed area, marine protected area, refuge, wilderness reserve, preservation, or other conservation area; nor does the designation affect land ownership. Federal agencies that undertake, fund, or permit activities that may affect these designated critical habitat areas are required to consult with NOAA Fisheries to ensure that their actions do not adversely modify or destroy designated critical habitat.

We designated critical habitat for five threatened Caribbean coral species, including the pillar coral. Twenty-eight mostly overlapping specific occupied areas containing physical features essential to the conservation of these coral species were designated as critical habitat. These areas contain approximately 16,830 square kilometers (6,500 square miles) of marine habitat. 


Regulatory History

On August 2023, NOAA Fisheries issued a proposed rule to change the status of pillar coral from Threatened to Endangered under the ESA. The most recent 5-year review recommended this status change based on population declines and susceptibility to stony coral tissue disease which has emerged since pillar coral was first listed as threatened under the ESA. In December 2024, a final rule was published to reclassify the pillar coral from a threatened to an endangered species; that rule became effective on March 21, 2025.
