Eastern Ecological Science Center


In 2020, the USGS Patuxent Wildlife Research Center and Leetown Science Center merged to create the Eastern Ecological Science Center (EESC). Our goals are to align our scientific capabilities with the most pressing conservation and management challenges; establish an engaged workforce that fosters high relationship trust with employees, partners and the public; and be a ‘go to’ organization for delivering actionable science to those responsible for conserving our nation’s natural resources for the enjoyment of current and future generations.
