We appreciate your interest in USGS' Sirenia Project. To help inform members of the media and public, we have provided relevant publications, reports, and websites. 

USGS scientists have devoted more than forty years to studying the biology and ecology of the West Indian manatee. Research conducted by our scientists is used to help inform management actions, including the recent U.S. Fish and Wildlife Service's announcement to downlist the West Indian manatee from endangered to threatened. Here, you will find information on the manatee science conducted by USGS. For more information, please use the contacts provided.
