Clear Cutting and Oil Field Development in the Swan Hills, Alberta, Canada Area

Oil and gas exploration leaves deforestation scars throughout the northern boreal forest region in Alberta, Canada near Swan Hills. This has also provided the development of new pulp mills on major rivers in the area. While there has been regrowth in some areas, the clearing is largely evident in the 2009 image, and gridlines of the third largest oilfield deposit in Canada (estimated to contain four billion barrels of oil) can also be seen in both of these images.

Comparison of images shows the result of human changes on the land. Of particular note is the clearing that is a result of deforestation.
