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. The 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!

Celebrate the Estuary in September

Oceanwise invitation

September is an exciting month at the GTM Research Reserve and at all 29 National Estuarine Research Reserves (NERRS) around the country. September 17th through the 23rd is National Estuaries Week and we will be holding many events to recognize this important time for the NERRS. Mark your calendars and join us for two big celebrations.

First, join us for Estuary Fest on Saturday, September 23, 2017. This FREE, family-friend event will feature music, art, games, food trucks, raffles, and fun activities — all focused on our precious coastal ecosystem and our beautiful estuaries. To learn more click HERE.

Then, celebrate with us for our eighth annual OCEANWISE – An Evening for the Estuaries on Saturday, September 30th, the Friends of the GTM Reserve’s signature fundraising gala to benefit the Reserve’s research, education, and stewardship programs.
