Grand Teton National Park
Grand Teton and Yellowstone National parks are both part of the Greater Yellowstone Ecosystem, comprising one of the largest intact temperate ecosystems left on Earth at nearly 18 million acres. This region is home to some of the most diverse and abundant wildlife populations in existence.
Grand Teton National Park provides refuge for many Northern Rockies species, but their territories don’t end at the park boundaries. In fact, species such as mule deer and pronghorn antelope travel many hundreds of miles each year to feeding and birthing grounds.
Spoiling Park Resources
Over the past decade, there has been a striking decline in the mule deer population in Wyoming as a result of habitat loss associated with energy development. Current estimates show mule deer numbers 46 percent below the Wyoming Game and Fish Department’s recommendations for a healthy population.
In February 2018, then-Interior Secretary Ryan Zinke issued a secretarial order to “improve habitat quality and western big game winter range and migration corridors for antelope, elk and mule deer.” However, the administration continues to sacrifice wildlife migration in favor of oil and gas interests. An analysis conducted by the Center for Biological Diversity found that in 2018, the Department of the Interior offered 1.2 million acres of pronghorn and mule deer winter habitat and migration corridors in the state of Wyoming to oil and gas development.
The Trump administration is interpreting its own migration order to mean that they will only defer leasing on a parcel if 90 percent of it falls within a wildlife corridor, a number that is arbitrary and unsupported by science. Oil and gas development along wildlife corridors would be devastating for species. Often, once a species encounters new roadblocks within its path, it disrupts foraging and breaks apart the herd, making it that much harder to reach their destination.
