Ga DNR Boating Caution: Slow Down, Watch Out for Manatees, Sea Turtles

With sea turtle and manatee sightings on the rise on Georgia’s coast, boaters should be on the lookout for these big and rare animals.

With sea turtle and manatee sightings on the rise on Georgia’s coast, boaters should be on the lookout for these big and rare animals.

Boat strikes are a leading cause of sea turtle strandings and manatee injuries and deaths. Manatees and all sea turtle species found in Georgia are protected by federal and state laws.

Tips on what to watch for in the coast’s murky waters differ. A “footprint” of swirls may mark a 1-ton manatee underwater. A 300-pound loggerhead sea turtle may show only its head when it surfaces. Sea turtles spend more time on the surface in spring, which puts them at greater risk of being hit by a boat.

What can boaters do? Be vigilant, be ready to slow down or steer clear, and if they do run into a sea turtle or manatee, stand-by and immediately contact the DNR at 800-2-SAVE-ME (800-272-8363). This provides biologists the best chance to help these animals and gather data useful in conserving them. Boaters will not be charged if operating their boat responsibly and the collision was an accident.

State Sea Turtle Program Coordinator Mark Dodd, a senior wildlife biologist with the Georgia Department of Natural Resources, emphasized that sea turtles are not limited to the ocean side of barrier islands. “They occur everywhere, not just in the ocean,” Dodd said. “They’re in the sounds, the estuaries, the tidal creeks.”

While nesting data indicates that these federally threatened turtles are rebounding, boat strikes that kill or injure reproductive females can undercut those gains. In 2019, about a third of the sea turtles found dead or injured on the beach or strand in Georgia suffered injuries consistent with being hit by a boat.

Manatees share a similar problem. These big, slow-moving mammals swim just below the surface, often putting them in harm’s way for oncoming boats. Watercraft collisions caused about 30 percent of the manatee mortalities documented in the state since 2000.

West Indian manatees, including the Florida manatee subspecies found in Georgia, are protected under the Endangered Species Act (they are listed as threatened) and the Marine Mammal Protection Act.

Manatees migrate from Florida to Georgia each spring, attracted by abundant marsh grass and other aquatic vegetation. Some move back and forth between the states through summer, until colder water temperatures in fall draw them south to Florida for the winter.

But from as early as March and into November, manatees occur in all tidal waters throughout coastal Georgia, said senior wildlife biologist Clay George of DNR’s Wildlife Conservation Section.

“We’ve had numerous sightings throughout coastal Georgia,” George said. “They could be anywhere from St. Marys to Savannah at this point. Boaters should be aware.”

Heeding low-speed and no-wake zones, particularly around docks where manatees eat algae growing on the structures, will reduce collision risks. So will sticking to the deeper channels when boating in tidal rivers and creeks. George said manatees “are often right along the edge of the marsh,” feeding on Spartina alterniflora, or salt marsh cordgrass.

Boaters and others are also encouraged to report any dead manatees and sea turtles they see. (If the turtle is tagged, include the tag color and number in the report if possible.)

DNR monitors sea turtle and manatee mortality through the Marine Turtle and Marine Mammal Stranding and Salvage Networks. The information gleaned, including from necropsies to evaluate cause of death, provides the primary index for threats these animals in Georgia’s coastal waters.

Sea Turtle Strandings

Report stranded sea turtles in Georgia by calling DNR at 800-2-SAVE-ME (800-272-8363). Stranding updates are available at (pick Georgia from “Select a Program”).

Reporting Manatees

If you see or photograph a healthy, injured or dead manatee, call DNR at (800) 2-SAVE-ME (800-272-8363). Note the date, time, location and number of manatees seen, plus the coordinates, if possible.

Manatees sometimes gather in groups to socialize. Large mating “herds” can top 20 individuals. Socializing is normal manatee behavior, senior wildlife biologist Clay George said. “Females sometimes swim into shallow water on purpose, apparently to avoid approaching males.”

Boaters can help protect manatees by:

  • Looking for manatees before cranking your boat’s motor.
  • Using caution when navigating in shallow water and along the edge of a marsh. Manatees cannot dive away from boats in these areas.
  • Heeding “slow speed,” “no wake” and manatee warning signs, especially around docks.
  • Wearing polarized sunglasses to reduce glare and make it easier to spot manatees below the surface.
  • Watching for trails of large swirls in the water called footprints that may be caused by manatees diving away from the boat.

Also, never feed manatees or give them fresh water. This could teach the animals to approach docks, putting them at greater risk of a boat strike.

And never pursue, harass or play with manatees. It can be harmful to manatees and it’s illegal.
