Study of shale gas and oil development impacts on forest in Appalachian Ohio
Emmitt Xavier Higgins, Xiaofang Wei
Abstract

About 30 percent of Ohio's land area is covered by forest. The forested areas are located over the Appalachians mountains, among which, more than 80 percent is owned by private landowners and 10 percent by federal and state agencies. Forests have a significant contribution to state employment and economy. Shale gas and oil development from the past decades has brought change to agricultural and forested lands; the peak development for Harrison and Carroll counties happened in the years of 2009-2019. In this study, first, image classification based on National Agriculture Imagery Program (NAIP) aerial photos was conducted for 2009 and 2019 for the wildlife areas around Leesville Lake, Atwood Lake, and Mohawk Lake. Tools in the ArcGIS Toolbox like Buffer, Reclassify, Zonal Geometry, and various others were used to deduce the number of forest patches, the shape, area, edge to area ratio, and interior habitats. Second, multiple years’ National Land Cover Database (NLCD) were utilized to study forest fragmentation analysis for Carrol and Harrison counties. Fragmentation metrics, including total edge length, edge density, and forest proportion were computed for the two counties, to quantitatively measure forest fragmentation in terms of numbers and sizes of forest patches. The results from Carroll and Harrison counties indicated an overall small change of these fragmentation metrics over the years. From 2001 to 2016, the total edge of density increased from 13.4% to 13.7%, patch number increased 1%, and forest core decreased 1%.
