In 1967, on the spring-fed waters of Florida’s Crystal River, a teenager named James “Buddy” Powell encountered a stranger in a rowboat. The man, a Cornell University graduate student, was looking for manatees — a species so obscure then that few had studied it in the wild. Powell, who knew the local springs better than most, offered to help. What began as a chance meeting became the start of a singular career in marine conservation, one that would span continents and redefine how the world saw a slow-moving, herbivorous mammal long mistaken for myth. Powell, who died on July 19 aged 70, devoted more than five decades of his life to understanding and protecting the West Indian manatee (Trichechus manatus) and its relatives. His research, from Florida to West Africa to Central America, led to the establishment of protected areas, reforms in coastal policy, and the training of a generation of local scientists. We can do the science, he once said, but if you don’t use that information to make change, then what’s the point? His fieldwork — practical, data-driven, and nearly always collaborative — pushed the boundaries of what was known about manatee behavior, distribution and threats. In the 1970s, as a U.S. Fish & Wildlife Service biologist, he helped lay the groundwork for federal protections. In the 1980s, he became the first to study West African manatees (Trichechus senegalensis) in the wild, producing a 21-country review that remains a foundational text. Later, in Belize, he created the country’s…This article was originally published on Mongabay
