Veracruz Coral Reef Faces Decline from Climate Stress and Port Expansion

Scientists report that the Veracruz coral reef, a National Park supporting the local economy and coastline protection, is losing the key species Acróporas palmata (deer‑horn coral). Causes identified include rising sea temperatures, water pollution, coastal construction and the fragmentation method used in coral nurseries, which can spread disease throughout the fragmented colonies.

A massive bleaching event in 2025 affected much of the reef, but over 80% of the colonies recovered as symbiotic algae returned. NGOs TerraVida and AIDA warn that recent port expansion projects have accelerated coastal erosion, damaged reefs and wetlands, and reduced catch areas for artisanal fishers, threatening the livelihoods of hundreds of families. The groups note that environmental assessments for the works omitted cumulative impacts, contrary to a 2021 Supreme Court order requiring stronger protection for the reef system.
