Texas boaters are increasingly encountering manatees in popular coastal marinas. Recent reports from across the Texas shoreline show the animals visiting marinas and other well-used boating areas.
Boaters, wildlife managers, and marine rescue personnel have been paying close attention to the sightings because of concerns about safety. But there is another side to the recent increase in sightings.
The locations attracting them this time often include busy areas such as marinas, commercial ports, and residential waterfronts.
Wildlife professionals were quick to caution residents and recreational water users who live and spend time in these areas.
They warned that while the sighting may be exciting, encouraging the animal to stay could create serious hazards.
Habitats expand as seasonal migration routes shift westward
Manatees generally are thought of as being found in the warmer coastal waters of Florida. Many people assume that’s the only place you’ll find them.
However, each summer, the Gulf of Mexico warms, and suitable habitats expand in area and quality.
As a result, some migrate hundreds of miles northward and westward from their primary wintering grounds in southern Florida. This migration pattern has resulted in sightings across multiple areas of the Texas coastline.
As marine mammal experts point out, reports have increased substantially in recent years.
The Texas Marine Mammal Stranding Network has documented numerous observations in local waters during warmer months. Some of these locations historically never hosted the species.
Most observations have come from calm bodies of water such as marinas, harbors, canals, rivers, and bayous.
These environments provide conditions where the animals are comfortable enough to remain for longer periods as they migrate through the region.
Why did manatees reach the Texas coast this summer?
Manatees require water temperatures above 68 degrees Fahrenheit to survive. They cannot endure prolonged exposure to cold temperatures.
When Gulf waters warm each summer, thousands of manatees migrate farther from their traditional winter ranges in southern Florida.
For several hundred miles along the Gulf Coast, including Texas coastal waters, they can swim, drink, and find suitable habitat while traveling. Availability of freshwater is important too.
Manatees need to consume freshwater periodically to quench their thirst.
Areas where freshwater enters bays, harbors, and coastal waterways attract many of them. Most sightings this summer occurred in areas with those characteristics.
Additionally, researchers have identified what appear to be broader environmental factors.
Researchers believe warming waters, changing habitats, and food availability are increasing manatee visits to the Texas coast.
The data is tracked by the Texas Marine Mammal Stranding Network.
Marinas present hidden hazards for visiting marine mammals
Wildlife rescue teams and conservation agencies are warning that manatees naturally seek freshwater sources for drinking.
Some are beginning to linger around marinas where freshwater enters the ocean.
While this may appear harmless to casual observers, wildlife experts warn that busy marinas expose the animals to significant risks, including vessel strikes.
As manatees spend more time around busy marinas, they face a much greater risk of colliding with boats traveling at speeds far greater than the animals can achieve.
Rescue organizations have specifically warned against feeding manatees or providing freshwater with hoses. Providing food or freshwater encourages manatees to linger in high-traffic zones, increasing their risk of injury.
Long-term tracking secures a safer future for coastal travelers
Wildlife authorities are urging boaters to watch for manatees along the Texas coast.
By reporting sightings, researchers gain valuable insight into where the animals travel throughout coastal waters during the summer months.
Until then, these migratory travelers remind us that Texas coastal waters are an ever-expanding part of a bigger picture.
For both humans and manatees, the best outcome is for the animals to keep moving rather than remain in crowded marinas.
