1883 Maps of Missouri and US Forest Density

1883 Map of US Forest Density US Forest Density 1883 Map 1883 Missouri Forest Density Map Twenty years after the Civil War, an officer in the Union Army and professor of horticulture at Harvard University published a set of 16 tree maps that visualized tree cover and the spread of tree species in America. The maps, the work of Charles Sprague Sargent, “provided the basis for conservationists and politicians to wrangle over issues of preservation and planning” until the passage of the McSweeney-McNary Forestry Research Act of 1928 made the process of monitoring forest conditions law, according to Slate.

These tree maps, commissioned by the United States Census and published in 1884, were compiled at the direction of dendrologist and horticulturist Charles Sprague Sargent. The complete set of 16 maps, digitized by the David Rumsey Map Collection, represents American forests by genus of tree, density, and position. The USDA estimates that while the total area of forested land in the United States has diminished by 30 percent since the date of European settlement in 1630, “75 percent of net conversion to other uses occurred in the nineteenth century.” Sargent’s project was meant to capture the contours of the forest as it stood in the Victorian era.  Sargent, a Bostonian and officer in the Union Army, was a professor of horticultureand the first director of the Arnold Arboretum at Harvard. As such, he was part of the first generation of professional American foresters; during his career, the Society of American Foresters, the U.S. Forest Service, and Yale’s School of Forestry and Environmental Studies were all founded. Historian Gordon G. Whitney writes that while census-takers collected data on the output of forest products per county beginning in 1840, Sargent’s report “contains some of the best information on the use and status of America’s forests in the nineteenth century.” Between the publication of Sargent’s report and the passage of the McSweeney-McNary Forest Research Act of 1928, which regularized the process of monitoring forest conditions, Sargent’s maps provided the basis for conservationists and politicians to wrangle over issues of preservation and planning. Scientists of the U.S. Forest Service produced a map of America’s woody biomass in 2012, using satellite data, computer modeling, and more traditional ground-based data. A rough comparison between this map and Sargent’s cordage density map (first below) reveals intriguing consistencies in pattern.   Click on the images below to reach zoomable versions, or visit the collection's page on the David Rumsey website. “United States, Showing the Relative Average Density of Existing Forests.” From Department of the Interior, Census Office,Sixteen Maps Accompanying Report On Forest Trees Of North America, By C.S.
