Coastal cleanup in Piñones:

Thank you to the 29 volunteers who joined us in La Pocita del Terraplén! On Saturday, December 9, 2023, we were part of the great coastal cleanup Limpieza de costas Deja una huella limpia en Piñones; a collaboration between LimPiaR, COPI, Arrecifes Pro-Ciudad, CRES, Surfrider Foundation and the Estuario, which covered the northern coastal region from Boca de Cangrejos to Vacía Talega.

At La Pocita, we collected 35 bags of solid waste; for a total of 1,153 pounds. We also removed 213 pans of oils and grease, equivalent to approximately 700 gallons. This collaboration is part of the actions for the reduction of aquatic waste of the Estuario. Learn more about these initiatives at:

Maintenance of Vivero Estuario:

Last Saturday, December 9, 2023, 12 volunteers joined our coastal resilience coordinator, Andreína Alexatos and our youth participation coordinator, Agnes Pagán, to the maintenance of Vivero Estuario, located at Centro TAU in Loiza. They processed 800 red mangrove propagules, 90 button mangrove seedlings, and 30 white mangrove seedlings. They pruned, watered, cleaned up, and took a big step toward restoring our shores. Thank you!
