Florida is home to some of the largest manatee populations on the planet, but unfortunately, human activities are the single largest cause of manatee deaths in the state. According to the 2019 Florida Fish and Wildlife Conservation Commission (FWC) Manatee Mortality Summary, boat-related collisions accounted for the majority of manatee deaths in Florida.
Manatees are slow-moving marine animals with poor eyesight and hearing, making them particularly vulnerable to collisions with boats, ships, and other watercraft. In 2019, boat-related collisions accounted for a full 59.2% of manatee deaths in Florida, making it the single largest cause of manatee deaths in the state.
The second leading cause of manatee deaths in Florida in 2019 was “unknown/undetermined”, which accounted for 14.8% of manatee deaths. Red tide, a type of harmful algal bloom, was the third leading cause, accounting for 10.4% of manatee deaths in the state. Other causes of manatee deaths in Florida included cold stress (7.7%), entanglement (3.7%), and disease (3.4%).
The FWC also reported that the number of manatee deaths in Florida decreased from 2018 to 2019. A total of 824 manatee deaths were reported in 2019, down from 855 in 2018. Of the 824 manatee deaths reported in 2019, 490 (59.6%) were caused by boat-related collisions.
The FWC has taken several steps to reduce manatee deaths in Florida. For example, in recent years, the agency has implemented a number of boat speed restrictions in areas where manatees are known to frequent. Additionally, the agency has created a number of manatee protection zones, which are areas where boat speeds are reduced even further. In addition to these measures, the FWC encourages boat operators to be vigilant and aware of their surroundings to reduce the risk of collisions with manatees.
The FWC is also actively working to protect and restore manatee habitats to ensure the species can thrive in the wild. The agency is actively working to protect manatee habitats from the threat of development and to improve the quality of existing manatee habitats by restoring and protecting mangrove and seagrass communities.
Manatees are protected by the Endangered Species Act, which was enacted in 1973, and by the Marine Mammal Protection Act, which was enacted in 1972. The U.S. Fish and Wildlife Service is responsible for enforcing these laws and has the authority to issue penalties for violations.
The FWC is actively working to reduce the number of manatee deaths in Florida, but the single largest cause of manatee deaths in the state remains boat-related collisions. The FWC encourages boaters to be aware of their surroundings to reduce the risk of collisions with manatees and to adhere to the boat speed restrictions that are in place in manatee protection zones.
Identifying The Leading Cause Of Florida Manatee Deaths
Florida is home to the most abundant population of manatees in the United States. However, in recent years, the population has declined due to a variety of factors. The most recent data from the Florida Fish and Wildlife Conservation Commission (FWC) shows that the leading cause of manatee deaths in Florida is boat strikes.
In 2019, a total of 633 manatees died in Florida. Of these, a total of 187 (29.5%) were killed by boat strikes. This is a significant increase from 2018, when the number of boat-related manatee deaths was 159 (26.9%). The second leading cause of manatee deaths in Florida is natural causes (186, 29.4%), followed by cold stress (90, 14.3%), undetermined causes (75, 11.9%), and red tide (45, 7.2%).
The number of manatee deaths due to boat strikes has been steadily increasing since 2016. This is likely due to the increasing number of boats on the water, as well as the rise in speedboat activity in manatee habitats. The FWC recommends that boaters reduce their speed in areas where manatees are known to inhabit, as well as to be on the look-out for manatees in shallow waters.
In an effort to reduce the number of manatee deaths, the FWC has implemented several measures. These include creating manatee protection zones, installing speed zones, and conducting public outreach campaigns to educate boaters on the importance of protecting manatees. Additionally, the FWC has established the Florida Manatee Rescue and Rehabilitation Partnership, which is a coalition of state and federal agencies, nonprofits, and private citizens that work together to rescue and rehabilitate injured manatees.
In order to protect Florida’s manatees, it is important to understand the leading cause of their deaths. Boat strikes are the leading cause of manatee mortality in Florida, and the FWC is taking steps to reduce the number of manatee deaths due to this cause. By following the FWC’s recommendations, boaters can help to ensure the safety of Florida’s manatees.
Examining The Impact Of Human Activity On Manatee Mortality
Manatee mortality is an increasingly important issue in Florida. Every year, hundreds of manatees are killed due to human activities, including boat collisions, fishing gear entanglement, and habitat degradation. Examining the impact of human activity on manatee mortality is key to helping protect and conserve these wonderful marine mammals.
The Florida Fish and Wildlife Conservation Commission (FWC) is the main agency responsible for monitoring manatee mortality in Florida. According to FWC data, the single largest cause of manatee deaths in Florida is boat collisions. In 2019, boat collisions accounted for an estimated 41 percent of human-caused manatee deaths in Florida, making it the single largest source of mortality for these animals. Other sources of human-caused manatee mortality include fishing gear entanglement, which accounted for 18 percent of human-caused manatee deaths in 2019, and habitat degradation, which accounted for an estimated 12 percent of human-caused manatee deaths.
To help mitigate the impact of human activities on manatee mortality, the FWC has implemented a number of conservation measures, including:
- Requiring boats to stay at least 25 feet away from manatees
- Requiring boats to obey local speed limits
- Establishing manatee sanctuaries
- Creating slow zones throughout the state
- Encouraging boaters to use properly marked channels
- Requiring the proper use of fishing gear
- Encouraging the use of artificial reefs to provide habitat for manatees
In addition to the measures listed above, the FWC also encourages boaters, anglers, and other recreational users of the water to be mindful of manatees and their habitat. The FWC also encourages those who encounter injured or distressed manatees to report them to the FWC’s Wildlife Alert Hotline at 888-404-FWCC.
By taking the necessary steps to reduce manatee mortality, we can help ensure that these gentle giants continue to thrive in Florida’s waters for years to come.
The single largest cause of manatee deaths in Florida is watercraft-related fatalities.
Since 2009, over 400 manatees have died from watercraft-related fatalities.
Reducing boat speed in areas with high concentrations of manatees, following seasonal speed zones, and obeying local laws and regulations are ways to reduce manatee deaths.
Organizations such as the Save the Manatee Club and the Florida Fish and Wildlife Conservation Commission (FWC) provide support and resources to protect manatees from becoming extinct.
You can help protect manatees by learning more about them, supporting organizations that work to protect them, and by following all laws and regulations that are designed to keep manatees safe.
Other causes of manatee deaths include red tide, cold stress, and natural predation.
Red tide can cause manatee deaths by causing respiratory irritation, which can lead to death from drowning or inhalation of water.
Cold stress can cause manatee deaths by decreasing the amount of energy available to the animals, increasing their susceptibility to disease, and making them more vulnerable to predation.
Creating warm-water refuges, managing water levels, and creating artificial warm-water sources can be done to reduce cold stress-related manatee deaths.
