Report Summary

The Social and Economic Benefits of Coral Reef Restoration in Puerto Rico

Key Points

Coral reef restoration can yield significant flood reduction benefits. These natural defenses were damaged in the 2017 hurricanes; their recovery would reduce the risks of further storm damages to nature, people and property.

RESUMEN DEL REPORTE

Los beneficios sociales y económicos de la restauración de arrecifes de coral en Puerto Rico

PUNTOS CLAVE

La restauración de los arrecifes de coral puede producir beneficios significativos en la reducción de inundaciones. Estas defensas naturales sufrieron daños a causa de los huracanes de 2017; su recuperación reduciría riesgos adicionales a la naturaleza, las personas y propiedades causados por tormentas.

This USGS Rapid Deployment Gauge was installed near Morovis, Puerto Rico, to monitor the Río Grande de Manatí after Hurricane Maria destroyed the permanent streamgage which typically monitors the river. USGS photo.

Bill Schulz, USGS Research Geologist, takes photographs of Puerto Rican hillsides from a U.S. Army helicopter to document landslides caused by Hurricane Maria.

This pair of Landsat 8 images shows the large-scale damage done to Puerto Rico. The lush green landscape in the 2016 image is replaced by a faded green. The strong winds stripped the leaves off trees to cause the degraded landscape. The forest is expected to recover.
