Welcome to the GTM Research Reserve!
Teeming with life, the Guana Tolomato Matanzas National Estuarine Research Reserve (GTM Research Reserve) is a dynamic, ever changing place with many interconnected habitats from the ocean to the forests. One of 30 National Estuarine Research Reserves in the country, this landscape protects and provides for a great diversity of plants and animals. People have historically changed and preserved this ecosystem. People are an important part of the future of this landscape. This is your reserve! Enjoy, share, and protect it. Visit us today!
