Howard's early academic experience - like his later career - involved mostly carnivore species. He conducted a 2-year project on black bear ecology in Tennessee and North Carolina before helping initiate the giant panda project in China. (With George Schaller, he trapped and released the first giant panda ever studied by radio-telemetry in the wild.) From 1981 through 1984, he conducted the most intensive examination of jaguar ecology that had ever been completed to date. The study took place in the Pantanal region of Brazil, also included cougars, and was partially funded by the National Geographic Society. Howard wrote his doctoral dissertation with the results of this research. From 1984-1987, Howard, along with Maurice Hornocker, conducted a re-examination of the cougar population in the Big Creek drainage of central Idaho, the site of Maurice Hornocker's original cougar work of the 1960s.
Howard completed a 5-year study of wildlife populations in northern Guatemala in 1997 and a 4-year study of black bears in western Maryland, both begun while employed by the University of Maryland system. After returning to the Hornocker Wildlife Institute in 1994, Howard provided oversight of the day-to-day operations of the Institute, including five cougar field studies, a black bear study in New Mexico and a wilderness research site in central Idaho. In addition, along with Maurice Hornocker, Howard initiated and co-directed the Siberian Tiger Project in Far Eastern Russia for nearly ten years. The Project, now in its eleventh year, tracks the movements of radio-collared tigers in an attempt to obtain data on the tiger's ecological requirements; the information is then used to develop conservation plans and activities to assist in a variety of ways in the conservation of the tiger and its habitat. In addition to work the tigers, the Project is also tracking brown bears, Asiatic black bears, Amur leopards, and several prey species. A comprehensive conservation plan for the Siberian tiger has been developed and is being promoted at all levels of Russian government.
As Director of the Global Carnivore Program, Howard is now in charge of the development of carnivore research and conservation initiatives throughout the field operations of the Wildlife Conservation Society.
With a variety
of scientific and popular publications on carnivore ecology, Howard is considered
an expert in research and conservation of carnivores, including tigers.
