|Abstract:||This technical note describes how records from General Land Office (GLO) surveys can be used to help guide ecosystem restoration planning. The GLO surveys were conducted in the 18th and 19th centuries, prior to the extensive settlement of the United States frontier regions. Throughout much of the newly independent United States, the GLO surveyors recorded information on hydrography and terrain, as well as specific data on vegetation composition and structure. When these notes and measurements are transferred to a Geographic Information System (GIS) and overlain on modern maps and aerial photographs, the information can provide insight into both natural and man-made changes that have occurred to the physical and biological environment of a region. This historical information can aid ecologists in establishing a reference condition for a study area and can help to define opportunities for ecosystem restoration. That process is illustrated here using the GLO survey data for a unique wetland complex called Grassy Lake (Figure 1) in southwestern Arkansas.|
