Message From The Manager
Along with the Guana Buffer Preserve, the Guana River Marsh Aquatic Preserve serves as the hub and headquarters of the Guana Tolomato Matanzas National Estuarine Research Reserve (GTMNERR). The estuary and uplands of the Guana River has been a valued resource for centuries of human populations with many changes taking place over time.
