2004 and 2008 (many decades after the last old-growth swamp forests had been logged) during searches that took place in Arkansas, Florida, and Louisiana. The Ivory-billed Woodpecker disappeared from the Singer Tract as it was being logged, but history might have been different if this habitat destruction had not occurred before Pough blossomed into "the foremost land preservationist of his time." One of Pough's colleagues, Don Eckelberry, visited the Singer Tract later in 1944 to make paintings of the Ivory-billed Woodpecker based on direct observations. In the years that followed, he produced the artwork for a series of Audubon field guides by Pough that put more of an emphasis on each bird's role in the ecosystem than field guides by Roger Tory Peterson that were published during the same period. In 1948, the American Museum of Natural History hired Pough as chair of the Department of Conservation and General Ecology. Between 1954 and 1956, he served as the founding president of the Nature Conservancy. In 1954, the president of the Audubon Society thought it would be impossible to raise funds in time to save the Corkscrew Swamp from logging that was set to begin in ten days, but Pough stepped in and raised the funding one day before the deadline. Pough was involved in numerous other conservation efforts for species such as the Bermuda Petrel and habitats such as Great Gull Island off the coast of Connecticut.
