Can oyster farms help protect our marshes from erosion?

New oyster aquaculture leases in the Guana and Tolomato Rivers are helping researchers explore an important question. If floating oyster cages help absorb wave energy from boat wakes, they could potentially reduce shoreline erosion and marsh loss.

To find out, GTM Research Reserve scientists are collecting shoreline elevation data and drone imagery near the lease sites. These measurements will serve as a baseline for future comparisons, helping researchers determine whether oyster aquaculture can help protect coastal wetlands over time.

Thanks to the generosity of Friends of GTM members, two brand-new ATVs are helping advance conservation at the GTM Research Reserve.

Through memberships, Adopt-a-Nest support, and other contributions, our members help provide the equipment and resources needed to protect and care for this remarkable place.

These new vehicles will support research, monitoring, and stewardship efforts across the GTM Research Reserve, helping staff and volunteers carry out their important work.

Thank you to our members for making projects like these possible. 💙

Weekend plans?

Follow a trail. Watch a bird. Spot a gopher tortoise. Cast a line.

At the GTM Research Reserve, every visit offers a chance to discover something new. Whether you're birdwatching, hiking, fishing, or simply enjoying the view, there are countless ways to connect with nature across nearly 76,000 acres of protected coastal habitat.

Start your adventure at the Visitor Center, where you can learn about the estuary, discover local wildlife, and find information on trails, programs, and upcoming events.

Happy World Ocean Day.

At the GTM Research Reserve, the Atlantic Ocean is part of a dynamic ecosystem that supports more than 76,000 acres of protected coastal habitat and the wildlife, healthy habitats, and natural resources found throughout our region.

Today, we celebrate the ocean and the vital role it plays in our coastal environment.

Good news from the beach!

Sea turtle nesting season is off to a strong start at the GTM Research Reserve with 87 loggerhead nests documented so far.

Each nest represents a remarkable journey and a reminder of why protecting these beaches matters.

Want to follow the season a little more closely? Our Adopt-a-Nest Program offers a meaningful way to connect with sea turtle conservation at GTM.

Heading to the beach this weekend? Small actions can have a big impact for the wildlife that depends on our coast during nesting season.

As sea turtles and shorebirds nest along Northeast Florida’s beaches this summer, please remember to:

• Give wildlife plenty of space
• Do not interfere with, pick up or otherwise disturb wildlife
• Fill in holes in the sand
• Knock down sandcastles before sunset
• Pack out all trash and fishing line
• Keep lights low at night
• Respect posted nesting areas

If you see injured wildlife or a disturbed nest, contact the Florida Fish and Wildlife Conservation Commission Wildlife Alert Hotline at 888-404-FWCC (3922).

Science looks a little different in the estuary. It’s muddy boots. Salty air. Long days on the water. Data collection powered by a team willing to go wherever the research leads.

Scientists from Villanova University joined GTM Research Reserve staff in the field to study freeze recovery and mangrove dynamics along Northeast Florida’s coast — research helping scientists better understand how changing environmental conditions are shaping coastal ecosystems over time.

Every monitoring trip, field survey and sample collected adds to a larger story about resilience, adaptation and stewardship in the estuary.

The estuary is full of small wonders. 🐝🌼

Pollinators like bees help native plants reproduce by moving pollen from flower to flower — supporting the coastal habitats, wildflowers, and wildlife that depend on them throughout the GTM Research Reserve.

A small but important part of nature’s balance.

ACTION ALERT: Protect National Estuarine Research Reserves 🌿

The Administration’s proposed FY 2027 budget would eliminate funding for the National Estuarine Research Reserve System (NERRS) — threatening coastal research, conservation, education, and wildlife protection nationwide.

Together, our voices can go even further.
