Report-breaking numbers of manatees have died in Florida the previous few years. However information from a not too long ago launched report might point out that that development is slowing down this yr—a minimum of thus far.
In response to a Florida Fish and Wildlife Conservation Fee, 431 manatees died throughout Florida from Jan. 1 to Aug. 25. In 2022, that determine was 669 manatees, and in 2021, it was 928 manatees. The five-year common of manatee deaths is 597.
The earlier unprecedented manatee mortality was linked to hunger in the course of the colder months when manatees migrated to and thru the Indian River Lagoon, the place nearly all of seagrass had been dying off. This began affecting the Indian River Lagoon, a habitat central to Florida’s manatee migration, in 2020.
This yr, far fewer deaths have been attributed to hunger, stated Martine DeWit, a analysis scientist with the FWC’s Fish and Wildlife Analysis Institute, in an electronic mail to the Miami Herald. In response to graphs on the FWC web site, manatee deaths linked to hunger have been in decline since early 2022.
“One of many essential causes for that is some restoration of seagrass in elements of the Indian River Lagoon, a development that began final summer season,” DeWit stated.
This spring, a number one reason behind demise was the pink tide bloom, which was first documented in November 2022. Throughout a pink tide, fast-growing algae produce toxins that may kill fish and different marine creatures. The pink tide bloom killed 85 manatees in southwest Florida this March, in keeping with the FWC.
Nevertheless, there’s a human-related exercise that continues to say the lives of Florida’s manatees—boating. Seventy-two manatee deaths thus far in 2023 have been linked to watercraft.
“What the info present is that watercraft collisions stay probably the most vital reason behind demise statewide through the years, whether or not the quantity goes up or down from yr to yr,” DeWit stated. “…That is in keeping with inhabitants fashions that determine watercraft-related mortality as one of many essential threats to the inhabitants long-term.”
