2013 has become the deadliest year ever for Florida’s endangered manatees. In total, 769 manatees have died so far this year from January 1st through October 29th, making it the largest annual manatee die-off in Florida since record-keeping began.
The previous record was set in 2010 when biologists with the Florida Fish and Wildlife Conservation Commission documented 766 dead manatees, of which hundreds died from cold stress. With more than two months still to go in 2013, nearly twice the number of manatees have already died than died in all of 2012.
According to Dr. Katie Tripp, Save the Manatee Club’s Director of Science and Conservation, two unusual mortality events in 2013, coupled with the regular threats manatees face on a daily basis, have been responsible for the unprecedented losses.
A record number of 276 manatees succumbed from exposure to a toxic red tide bloom in southwest Florida, centered in Lee County. Meanwhile, on Florida’s east coast, an unusual mortality event claimed more than 100 manatee lives in Brevard County this year.
“This year’s record-breaking manatee mortality is a loud and clear signal that our waterways are in trouble,” says Tripp, who explained that of the total number of manatee deaths so far this year, 123 were stillborn, newborn, or young calves less than five feet in length, which sets another annual record for this category of mortality.
Of these, at least 49 were found in Brevard County, at the epicenter of the unusual mortality event linked to a variety of algal blooms and loss of 47,000 acres of seagrass since 2010.
Patrick Rose, who is an aquatic biologist and the Executive Director of the Club says, “With 2013’s catastrophic loss of manatee lives coming so close on the heels of the mass mortality suffered during 2010, the already difficult job to ensure the survival of these gentle and defenseless marine mammals has been made all the more challenging, and it’s not over yet.
What we put into our waters, how much we pump from our aquifer and draw from our springs and rivers, together with how we use our waterways, all has an impact on our own lives and the lives of every aquatic species. We must be better stewards of our waters and waterways or suffer even more severe consequences going forward.”
Save the Manatee Club reminds the public that November is Manatee Awareness Month in Florida – the time of year when manatees are on the move, making their way to important winter warm-water sites.
The Club offers a variety of ways for the public in Florida to be directly involved with manatee protection during November and throughout the year. Free public awareness waterway signage, boating banners and decals, waterway cards, and educational posters are produced by the Club. The bright yellow waterproof banner which cautions, “Please Slow: Manatees Below,” can assist in warning boaters to slow down for manatees who may be in the area.
Shoreline property signs and matching boat decals are also available, featuring the Florida Fish and Wildlife Conservation Commission’s hotline number (1-888-404-3922) for reporting sick and injured manatees. Boater and diver awareness posters are also available for dive shops, marinas, businesses, visitor centers, classrooms and libraries.
Family-friendly outdoor signs are produced by the Club and distributed to state, municipal, and county parks; marinas; and other sites where human/manatee interactions can be a problem. Requests for any of these free materials can be sent via e-mail to email@example.com or by calling toll free at 1-800-432-JOIN (5646).
“The public’s ongoing participation in manatee conservation, in Florida and outside the state, is essential for the welfare and protection of the species and the aquatic habitats upon which they depend,” says Rose.
