Informational tour of the Condado Lagoon:

During the family day at the Condado Lagoon Natural Estuarine Reserve this past Saturday, December 2nd, we held an informational tour, courtesy of our Public Participation Specialist and Bird Census Coordinator, Eliezer Nieves, and our Environmental Educator, Coral Avilés. The participants learned about the importance of this estuarine ecosystem, and conducted a bird census in the area.

Thank you to the friends and neighbors who joined us during the family day, and the Cine del Estuario screening. See you next time!

Planting of coastal vegetation in Luquillo:

On Saturday, December 2, 14 volunteers accompanied our Coastal Resilience Coordinator, Andreína Alexatos, in the planting of around 750 coastal trees on half a hectare of the Northeast Ecological Corridor in San Miguel, Luquillo, as part of the coastal resilience module of the Estuario Certification for Citizen Scientists.

We are grateful for the participation of all the volunteers and the collaboration of EcoCulture, the DNER, the Coalition for the Ecological Corridor of the Northeast and ReForesta.
