Leiburg was a Swedish-born bryologist, forester, and botanical explorer. As a field agent for the USDA, Botanical Division, Leiburg collected botanical specimens in Idaho, Washington, Oregon, and Nevada from 1895-1896. In July and August, 1896, Leiburg worked in conjunction with botanist Frederick Vernon Coville to collect botanical specimens in eastern Oregon, including the vicinity of Crater Lake. Leiburg also worked with the U.S. Geological Survey from 1897–1903, was a forestry inspector in the Philippines from 1904–1905, and investigated the timber supply of the Forest Reserves of Montana, Idaho, Oregon, California, and Arizona from 1905–1906. A particular issue of interest for Leiberg was the overgrazing of lands, leaving them susceptible to the effects of devastating fires. He died in Leaburg, Oregon, on October 28, 1913.
