Estuario Weekly Update

This week we continue pushing the protection and restoration of the waters connected to the San Juan Bay Estuary (SJBE), with actions ranging from reducing aquatic waste to new opportunities for citizen and professional engagement. Below we share active recycling initiatives after the holiday season and an extensive agenda featuring Estuario’s Certification for Citizen Scientists’ workshops and field experiences. We invite you to get informed, participate and be part of the solutions that strengthen the ecosystems of our communities.
