Manatee Mortality Statistics

Since 1974, biologists have collected mortality statistics for Florida manatees. Researchers have determined both the number of manatee deaths in each Florida county and the probable cause of death for each carcass. Analysis of these data allows tracking of changes and trends in mortality throughout the years.
