Historical landscape change is important when evaluating the effects landscape plays on an ecosystem. Geology, land use, slope and streams are all intertwined.
Lancaster County, Pennsylvania is home to an urban and agricultural landscape. It is marked by large expanses of farmland and growing urban centers. The location of my study was west Manhiem Township. It is a small urban area that has seen a lot of growth in the past fifty years. The site exists on the boundary between the urban town and the rural farmland and thus has been impacted by the encroachment of the town. Most notably, is the change in stream hydrology from 1957 to 1971.
Lancaster, PA is known for its fertile soils. Throughout history this has been exhibited through the popularity of agricultural practices in the area. This study was conducted in a section of Manheim Township, and analyzed the development of Neff Elementary School and Manheim Township High School from 1940 – 2008 via historic aerial photography (1940, 1958, 1971) and a relatively recent (2008) orthorectified image.
