The bison of North Dakota are protected species along with the black footed ferret. The bison cannot be hunted and it's habitat are protected. That means the pipeline can't be built there. The habitat obviously extends to the very place the Native Americans had taken a stand against the pipeline.
WWF (click here) leads innovative work with public agencies, tribal nations, ranchers
and other partners to create a sustainable future for the Northern
Great Plains. Our two main goals are to sustain and enhance biodiversity across the Northern Great Plains and to restore two flagship species—bison and black-footed ferrets—where
possible within the region. Achieving these goals requires a
multi-pronged approach that recognizes unique challenges and
opportunities from the local level all the way up to US federal policy
and global initiatives. WWF is a leading voice for grasslands, and
advocates for the incredible wildlife and communities of the Northern
Great Plains.
Interestingly enough, the Bison/Buffalo herd noted in a film of the Standing Rock Sioux tribe protests is a RESTORED herd. The Bison was wiped out and had to be returned to the land. This is definitely a protected herd that has been restored to it's rightful habitat.
Many of the iconic animals (click here) in Theodore Roosevelt National Park are
mammals. Animals such as the American bison and the black-tailed prairie
dog are relatively easy to spot. Others such as big horn sheep or elk
are more difficult to find, due to their behaviors and/or preferred
hours of activity.
Many of the large mammals living in the park today were not present
at the time of the park's establishment in the 1940s. Bison, elk and
bighorn sheep had all been extirpated from this region. Deer and
pronghorn were rare. Various reintroduction programs proved successful
in returning native wildlife to the ecosystem. Not only do they
represent the experiences of Theodore Roosevelt, but they provide
visitors with their own experience of a wild prairie....
The habitat is extensive and cannot be disturbed. The herd was originally restored at "Theodore Roosevelt National Park" and have grown as is necessary to maintain a viable herd.
"...its toughness (click here) and hardy endurance fitted it to contend with
purely natural forces...to resist cold and wintery blasts or the heat of
the thirsty summer, to wander away to new pastures, to plunge over the
broken ground, and to plow its way through snow drifts or quagmires." Theodore Roosevelt
As a matter of fact there were Yellowstone Buffalo moved to two areas of Montana as well as the ones below from Canada, to return them to their former habitat. The Native American reservations are vital to the return of the American Buffalo to it's former habitat.

Billings Mont. - Decsendants of a bison herd (click here) captured and sent to Canada ore than 140 years ago will be relocated to a Montana American Indian reservation next month, in what tribal leaders bill as a homecoming for a species emblematic of their traditions.
The shipment of animals from Alberta's Elk Island
National Park to the Blackfeet Indian Reservation follows a 2014 treaty
among tribes in the United States and Canada. That agreement aims to
restore bison to areas of the Rocky Mountains and Great Plains where
millions once roamed.
"For thousands of years the Blackfeet lived
among the buffalo here. The buffalo sustained our way of life, provided
our food, clothing, shelter," Blackfeet Chairman Harry Barnes said. "It
became part of our spiritual being. We want to return the buffalo."...
These herds are very well documented and are definitely connected to the Native American lands. So, the North Dakota herd is connected through cultural ties to the National Park and Native Americans making a stand to end the assault by the petroleum industry.
These herds cannot be disturbed, especially their habitat. I don't know who gave the cops to bring tanks and humvees to this land, but, they are violating the protections of the buffalo herd as well as the Native Americans that value the land for it's historical purposes.
Where did anyone get the idea it was okay to roll heavy equipment across these lands disturbing the vital habitat of these herds? They are "W"rong. The equipment and the cops need to be removed from the lands and never return.
