Developing a Genetic Diversity Conservation Model for the Threatened Coral Acropora palmata in San Andres Island, Colombian Caribbean

Alexandra Pineda-Muñoz

Acropora palmata, a key reef-building coral species, is critically endangered due to climate change, coral bleaching, and disease outbreaks. This project aims to assess the genetic structure of Acropora palmata populations in San Andres Island, Western Caribbean in Colombia, and compare them with other populations in the region. By identifying resilient genotypes and phenotypes that can withstand environmental stressors, the project will inform conservation and restoration efforts for this vital species.

Through DNA analysis and ecological assessments, the project will develop a conservation protocol for Acropora palmata, incorporating genetic diversity into restoration strategies. It will also identify resilient populations that can serve as a source for restoring degraded reefs. Furthermore, educational and community engagement programmes will be implemented to raise awareness among local stakeholders, especially the Raizal community, who depend on coral reefs for their cultural and economic wellbeing.

This project will contribute to the long-term resilience of the coral reefs in the Seaflower Marine Protected Area (MPA), a UNESCO Biosphere Reserve, and will serve as a model for similar conservation efforts in the Caribbean. By combining scientific research with local knowledge and engagement, this initiative seeks to restore and protect the marine heritage of San Andres Island for future generations.
