Millions of acres of land across the U.S. and Canada has been taken over by oil and gas development in the last 12 years, according to a new study.
The study, published Friday in Science, tallied up the amount of land that’s been developed to house drilling well pads, roads, and other oil and gas infrastructure in 11 U.S. states and three Canadian provinces. It found that between 2000 and 2012, about 3 million hectares (7.4 million acres) have been turned over to oil and gas development, a stretch of land that, combined, is equal to three Yellowstone National Parks.
This land takeover can have ecological consequences, according to the report.
Most of the land converted into drilling operations was cropland and rangeland — a term that encompasses prairies, grassland, shrubland, and other ecosystem types — and roughly 10 percent was woodland. Wetlands, according to the report, were mostly spared by oil and gas developers, though a very small amount have been converted into oil and gas sites.
Land takeover due to oil and gas development can have a number of negative consequences, the report states. It removes vegetation that’s important for food, habitat, and carbon storage, and it also fragments ecosystems in such a way that can disrupt the natural behavior of wildlife....
... “The point we’re trying to make with this paper is not so much that some huge fraction of current land area has been de-vegetated, as much as the trajectory of drilling, (consuming) a half-million acres per year,” he said. “If we continue that to 2050, you get to some seriously big amounts of land.”... more here
