As a Mammalian Wildlife Ecologist, Dr. Franklin's research interests have involved a number of species, including prairie dogs, raccoons, white-tailed deer, guard-llamas, and South American foxes and pumas. The primary focus of his research, however, has been on the behavioral and population ecology of the wild camelids of South America. His initial work was with endangered vicuña at the Pampa Galeras National Vicuña Reserve in the high Andes of southern Peru. He then conducted and directed field research on the guanaco in Tierra del Fuego and Torres del Paine National Park in southern Chile from the mid-1970s until his retirement in 2000, after which he conducted field research on an island population of guanacos in the Falkland Islands. He is currently writing a book on the Guanacos of Patagonia.
