Dense unconventional shale gas extraction activities have occurred in Appalachian Ohio since 2010 and they have caused various landcover changes and forest fragmentation issues. This research investigated the most recent boom of unconventional shale gas extraction activities and their impacts on the landcover changes and forest structural changes in the Muskingum River Watershed in Appalachian Ohio. Triple-temporal high-resolution natural-color aerial images from 2006 to 2017 and a group of ancillary geographic information system (GIS) data were first used to digitize the landcover changes due to the recent boom of these unconventional shale gas extraction activities. Geographic object-based image analysis (GEOBIA) was then employed to form forest patches as image objects and to accurately quantify the forest connectivity. Lastly, the initial and updated forest image objects were used to quantify the loss of core forest as the two-dimensional (2D) forest structural changes, and initial and updated canopy height models (CHMs) derived from airborne light detection and ranging (LiDAR) point clouds were used to quantify the loss of forest volume as three-dimensional (3D) forest structural changes. The results indicate a consistent format but uneven spatiotemporal development of these unconventional shale gas extraction activities. Dense unconventional shale gas extraction activities formed two apparent hotspots. Two-thirds of the well pad facilities and half of the pipeline right-of-way (ROW) corridors were constructed during the raising phase of the boom. At the end of the boom, significant forest fragmentation already occurred in both hotspots of these active unconventional shale gas extraction activities, and the areal loss of core forest reached up to 14.60% in the densest concentrated regions of these activities. These results call for attention to the ecological studies targeted on the forest fragmentation in the Muskingum River Watershed and the broader Appalachian Ohio regions.

The remarkable results of “shale gas revolution” in the USA have provoked a huge interest in Chinese energy circles. Beijing seriously considers the prospects of developing its abandoned domestic shale gas resources, which might result in a second “shale gas revolution”, this time in Asian region. Developing shale gas would help Beijing to bridge the gap between energy consumption and supply, and would also create a viable alternative to coal. However, the technology of shale gas extraction (hydraulic fracturing) is highly controversial, and raises a lot of concerns among environmentalists. “Fracking” has already been banned in a number of European states and there, and is a subject to moratorium in US states of New York, Connecticut and New Jersey. The core question is whether China can successfully adapt the extraction technology to its geologic conditions, and most importantly whether “fracking” of shale gas will help to alleviate the environmental degradation caused by rapid GDP growth, and help to increase energy security of Chinese economy.
