For as long as humans have existed, we have always had connections with animals.

It seems that our fundamental relationship with animals is primarily utilitarian. We hunt deer for meat, we shelter chickens to harvest eggs and we sheer sheep for wool.

The list goes on and on, because we as humans depend profoundly on animals. The domestication of animals has brought substantial changes not only in our relationship with them, but has also influenced species as a whole—so much so that in some cases, domesticated animals have few similarities to their wild ancestors.

"We stand for wildlife"—a motto prominent on the Wildlife Conservation Society's (WCS's) website. Established originally as the New York Zoological Society (NYZS) in 1895, WCS has over a century of dedicated experience protecting wildlife and habitats around the world.

Bison are one of the flagship species that has been a part of WCS's conservation portfolio for more than 100 years.

In 1905, when fewer than 1,000 bison remained in North America, the NYZS founded the American Bison Society (ABS) to help save bison from extinction.

Imagine crouching in the grass with a bison hide on your back while massive 2,000 pound animals graze a few feet from you.

Moments later, you bellow like a stressed calf, wanting the herd to follow the noise.

You continue to do so until you are close to a cliff and then you start running as fast as you can towards the cliff while a herd of 40 bison stampede behind you.

The InterTribal Buffalo Council (ITBC) was established in 1992 as a grassroots organization to restore bison to Tribal lands.

The ITBC coordinates with the National Park Service to facilitate the transfer of bison culled from national park lands to Tribal lands, facilitates educational programs and provides technical assistance to 56 Tribes.

By the beginning of the 1900s, bison were not only teetering on the edge of extinction, but they were also about to endure the ultimate genetic ordeal.

Think about the basic genetics you may have learned in school and every vocabulary term you needed to memorize.

Bison were about to be put to the ultimate test.

A tiny, rare blue butterfly with a one inch wing span is making a come-back in central Wisconsin, in part due to the largest land mammal in North America.

Originally ranging across 12 states from Maine to Minnesota and at sites in the Canadian province of Ontario, the federally endangered Karner blue butterfly is thriving at the 9,150 acre Sandhill State Wildlife Area in central Wisconsin.

Have you ever tried an online search for the word "buffalo?"

If you do so by Google, you will see that there are over 1.3 trillion online references to that single word-buffalo!

Countless elements influence and threaten the health of wildlife species and the habitats they live in.

Disease, such as brucellosis, represents one of these aspects and can pose a significant risk to the conservation of species, especially a species such as the American bison.

Brucellosis is an infectious disease caused by the bacterium Brucella abortus and is commonly transmitted between elk, bison and domestic livestock.

Were all these bison the same species, the same animal? Indeed, when are bison not exactly the same?

Through extensive long-term natural history studies and scientific investigations, even to the genetic and cellular levels, we now understand that there is one species of bison that is comprised of two subspecies in North America and another species of bison in Europe.

If someone asked you to describe the word "thanksgiving," what would you say?

Would it be a day to give thanks and be with friends and family? A day to watch football and eat a large turkey dinner?

Or would you describe the first Thanksgiving and possibly the more tragic events that followed for the American Indians?

The decimation of the North American bison from tens of millions of free roaming animals to fewer than one thousand by the beginning of the 20th century was a tragedy and a confirmation of the rapacious nature of humankind.

The sound of the bison bellow was nearly permanently silenced.

Can you imagine being struck by lightning? Sparky, a bison at Neal Smith National Wildlife Refuge in Iowa knows exactly what it's like! Sparky was struck in 2013 and is doing surprisingly well.

Just like cows and elk, bison have four stomachs. While you may think this means that bison can eat four times as much as animals with one stomach, this is not the case.

Their four-chambered, ruminant digestive system allows for the absorption of cellulose—a fibrous plant material that is hard to breakdown. With this ability to digest cellulose and their selective grazing habits, one of bison's greatest influences to the prairie ecosystem is based on their foraging ecology.

After four years of outreach to Congress and the White House, by the Wildlife Conservation Society, its partners the InterTribal Buffalo Council and National Bison Association and 60-plus Vote Bison Coalition members, the National Bison Legacy Act was signed on May 9, 2016, officially making the bison our national mammal. This historic event represents a true comeback story, embedded with history, culture, and conservation.

Every year when mid-winter arrives, snow can blanket the northern Great Plains, temperatures can drop well below zero and the winds can howl unmercifully and yet bison remain alive and well on the hostile landscape. Indeed, bison have evolved digestive, physiological, and behavioral strategies that allow them to survive some of the harshest weather in North America.

One story, the legend of the White Buffalo Calf Woman, or Ptesan Wi, is a very sacred story for the American Indians. Many American Indians, such as the Sioux, Cherokee, Navaho, Lakota, and Dakota, celebrate the white buffalo calf and incorporate Ptesan Wi'steachings in their prayers.

Along the Utah-Colorado state border sits a mountain range resembling a shelf of books. This 1.2 million acre range, known as the Book Cliffs, is home to magnificent sandstone buttes, pinyon-juniper filled arroyos, and a herd of roughly 400 bison. This bison herd is only constrained by the steep and rugged canyons found in the Book Cliffs: it truly is a free-ranging and wild population.

As the summer flowers begin to appear and the days start to warm, the prairie ecosystem is soon dotted with newborn bison. These young calves, born mostly between March and June, are born with an orange-brown to reddish-brown "buff" color, which slowly darkens to adult coloration by four months.
