November 11, 2020 — The following was released by NOAA:
Coral reefs in both the Pacific and Atlantic oceans received a “fair” score in the first-ever condition status report for U.S. coral reefs released by NOAA and the University of Maryland Center for Environmental Science (UMCES) today. While the overall scores were “fair,” the report highlights coral reefs are vulnerable and declining. This is the first time coral reefs in all U.S. states and territories have been assessed using standardized monitoring data, creating datasets that offer a baseline of coral health on a national scale.
The U.S. Coral Reef Condition Status Report was developed by NOAA’s National Coral Reef Monitoring Program and UMCES’s Integration and Application Networkoffsite link using data collected between 2012 and 2018. The scores are denoted as “very good,” “good,” “fair,” “impaired,” and “critical.” The report was based on four categories when assigning a score: corals and algae abundance, reef fish populations, influence of climate on coral reefs, and human connections to reefs.
“Considering the more than $3.4 billion in annual economic benefits of coral reefs, these reports and the policy actions that they will inform are critical to our American Blue Economy,” said retired Navy Rear Adm. Tim Gallaudet, Ph.D., assistant secretary of commerce for oceans and atmosphere and deputy NOAA administrator.
Coral reefs near higher density human populations are degraded, which is likely due to local stressors including land-based sources of pollution and damaging impacts from fishing.
“To conserve and restore coral reefs, we need to understand the overall condition of these ecosystems,” said Jennifer Koss, director of NOAA’s Coral Reef Conservation Program. “This report represents a snapshot of reef condition and is a great resource for communities and decision-makers throughout the nation. We hope the report starts a dialogue about the various factors and potential solutions to the threats affecting coral reefs.”
Greatest among the threats to coral reefs is climate change, according to the report. Warmer, more acidic seawater is negatively affecting coral reefs globally, no matter how remote they are.
“These status reports clearly show the impacts people are having on coral reef ecosystems,” said Heath Kelsey, director of UMCES’s Integration and Application Network. “Our work in the Pacific and Atlantic Oceans shows a dire outlook for coral reef ecosystem health, from warming ocean waters, fishing, disease, and pollution from the land. Of all of these, climate change is the single biggest threat to shallow water coral reefs in the U.S., and worldwide.”
