SNIP: In January 2015 North Dakota experienced one of the worst environmental disasters in its history: A pipeline burst, spilling nearly 3 million gallons of briny, saltwater waste from nearby oil-drilling operations into two creek beds. The wastewater, which flowed all the way to the Missouri River, contained chloride concentrations high enough to kill any wildlife that encountered it.

It wasn’t the first such disaster in the state. In 2006 a spill of close to 1 million gallons of fracking wastewater into the Yellowstone River resulted in a mass die-off of fish and plants. Cleanup of that spill was still ongoing at the time of the 2015 spill, nearly a decade later.

Spills like these highlight the dangers that come with unconventional fossil-fuel extraction techniques that go after hard-to-reach pockets of oil and gas using practices like horizontal drilling and high-volume hydraulic fracturing (otherwise known as fracking).

But events like these massive spills are just the tip of the iceberg. Other risks to wildlife can be more contained, subtle or hidden.

And while many of the after-effects of fracking have grabbed headlines for years — such as contaminated drinking water, earthquakes and even flammable faucets — the consequences for wildlife have so far been left out of the national conversation.

But those consequences are very real for a vast suite of animals including mussels, birds, fish, caribou and even fleas, and they’re as varied as the species themselves. In some places wildlife pays the price when habitat is destroyed. Elsewhere the damage occurs when water is sucked away or polluted. Still other species can’t take the traffic, noise and dust that accompany extraction operations.

All this damage makes sense when you think about fracking’s outsized footprint.

It starts with the land cleared for the well pad, followed by sucking large volumes of water (between 1.5 and 16 million gallons per well) out of rivers, streams or groundwater.

Then there’s the sand that’s mined for use during the fracturing of underground rock to release natural gas or oil. There are also new pipelines, compressor stations and other related infrastructure that need to be constructed. And there’s the truck traffic that surges during operations, or the disposal of fracking wastewater, either in streams or underground.

The cumulative footprint of a single new well can be as large as 30 acres. In places where hundreds or thousands of wells spring up across a landscape, it’s easy to imagine the toll on wildlife — and even cases with ecosystem-wide implications.

The most obvious threats fracking poses to wildlife comes in the form of habitat loss.

As rural areas become industrialized with each new well pad and its associated infrastructure, vital habitat for wildlife is altered or destroyed.

And it’s not just the area containing the well. The land or water just outside of the operation, known as “edge habitat,” also degrades with an increase in the spread of invasive plant species, among other concerns.

And large-scale development, such as miles-long pipelines, can change the way species move and hunt, often resulting in an increase in predation. The oil and gas development in Alberta, Canada, for example, created “wolf highways” that gave the predators easy access to an endangered herd of woodland caribou.

Roads, another kind of fragmentation, can be particularly dangerous for wildlife. A single fracked well can be responsible for 3,300 one-way truck trips during its operational lifespan, and each journey can injure or kill wildlife large and small. After all, it’s hard to get out of the way of a tanker truck carrying 80,000 pounds of sand.

And then there’s the big picture. Drilling within large, “core” forest areas previously located far from human development can be permanently detrimental for species such as migratory songbirds.
