The Importance of Estuaries
Estuaries stand as critical ecological hubs, and at GTMNERR (Guana Tolomato Matanzas National Estuarine Research Reserve), we recognize and celebrate its profound importance. Serving as the meeting point between freshwater rivers and saltwater seas, estuaries boast unparalleled biodiversity and act as vital nurseries for countless marine species. These dynamic ecosystems also provide essential habitat for migratory birds, serving as key rest stops during their journeys.
GTMNERR is committed to studying and preserving these estuarine environments, as they play a crucial role in maintaining water quality, mitigating coastal erosion, and acting as buffers against storm surges.
- By understanding the significance of estuaries locally and globally, we strive to foster appreciation and stewardship, ensuring the long-term health of these invaluable ecosystems for generations to come.
- Join us in the exploration and conservation of the precious estuarine landscapes that define our natural heritage.
Science to Management
At GTMNERR, scientific findings are effectively translated into management strategies through collaboration. The Management Advisory Group, which includes professionals and community members, and the Technical Advisory Group of experts work together to inform decision-making.
This partnership ensures that the latest research guides sustainable management practices. As a result, GTMNERR advances scientific knowledge while preserving estuarine ecosystems for nature and local communities.

State of the Reserve
The GTM Research Reserve hosts the “State of the Reserve,” which highlights projects conducted within the reserve boundaries. Researchers, stewards, and educators worldwide present findings on coastal wetlands, oysters, habitat restoration, water quality, population dynamics, and more.
- This annual science symposium is an opportunity to learn about long-term monitoring efforts like the System-Wide Monitoring Program (SWMP), which highlights the effect of climate change on the reserve’s ecosystems and serves as a baseline to examine change over time.
