Fredrick Swanson tells the story of Guy M. Brandborg and his impact on the practices of the U.S. Forest Service. As supervisor of Montana s Bitterroot National Forest from 1935 to 1955, Brandborg engaged in a management style that promoted not only the well-being of the forest community but also the social and economic welfare of the local people. By relying on selective cutting, his goal was to protect the watersheds and wildlife habitats that are devastated by clear-cutting, and to prevent the job losses that follow such practices. Following his retirement, he became concerned that his agency was deviating from the practice of sustained-yield management of the forest s timber lands, and led a highly visible public outcry that became known as the Bitterroot controversy. Brandborg s behind-the-scenes lobbying contributed materially to the passage of the National Forest Management Act of 1976, the single most important law affecting public forestry since the creation of the Forest Service.Meticulously written, The Bitterroot and Mr. Brandborg articulates Brandborg s Progressive-era idealism and is based on extensive archival research in collections throughout the Rockies and the Northwest, including the Brandborg family papers. Swanson s crisp narration of how one national forest supervisor understood the intricate connection between the grasslands and forests under his care and the communities that were so dependent on these invaluable resources, opens a much larger story about the meaning of public lands in a democratic society.
