At a recent forum, researchers from Penn State University discussed how natural gas operations can threaten wildlife and how careful planning is required to avoid harming wild animals and their habitat. According to a news report, the researchers explained that "The location of a Marcellus Shale drilling pad site could mean the difference between life or extinction for some of Pennsylvania's unique wildlife." Recent reports from Pennsylvania and West Virginia have also concluded there are significant risks to fish and other aquatic life.
Additionally, a North Dakota Game and Fish Department task force has drafted a report on the impacts of oil and gas operations on North Dakota's wildlife. According to a news report, the draft report found risks of diminished hunting and outdoor recreational opportunities through the loss of primary habitat due to direct and indirect effects of oil and gas development. The task force reportedly found that, under certain scenarios, mule deer numbers in the primary range could decline by 25% to 50% in the next 20 years. Recent reports from Wyoming have found substantial declines there in mule deer population.
