Badlands National Park is now home to half the world’s rarest wild carnivore

Shep’s Discovery Sparked the Black-Footed Ferret Revival

In 1979, the black-footed ferret was gone. Dead. Extinct. Then a ranch dog named Shep changed everything.

On September 26, 1981, Shep killed a strange animal on a Wyoming ranch. That “strange animal” turned out to be a species back from the dead.

Scientists soon found 130 more ferrets, but disease hit hard. By 1987, just 18 remained, with only seven able to breed.

From this tiny group came a miracle. Scientists released 147 captive-bred ferrets into Badlands National Park starting in 1996.

Today, about 120 ferrets roam the park’s Conata Basin, marking one of wildlife’s greatest comeback stories. The Ben Reifel Visitor Center tells this tale in full.

Ferrets Vanished From American Prairies By The Late 1970s

Black-footed ferrets got listed as endangered in 1967 when ranchers killed off prairie dogs, the ferrets’ main food. The last wild group in South Dakota died out by 1974.

Things got worse when the final captive ferret died in 1979 at a wildlife center. Scientists thought the species was gone forever.

These prairie bandits ate prairie dogs and lived in their tunnels.

A Ranch Dog Named Shep Made History With One Catch

On September 26, 1981, a Wyoming ranch dog named Shep killed what looked like a weird weasel on the Hogg Ranch near Meeteetse. The Hogg family took it to a local taxidermist who knew it was special.

He called wildlife officials right away. This lucky find shocked experts who thought ferrets were gone for good.

Shep found the first confirmed black-footed ferret since the South Dakota group vanished seven years earlier.

Wildlife Experts Found A Hidden Colony Living Under Their Noses

Biologists rushed to the Hogg Ranch and found about 130 black-footed ferrets living in prairie dog towns. This group was the only known wild ferrets left anywhere.

Scientists set up night watches to count the animals and study how they lived. The large prairie dog colonies across the ranch gave these rare hunters plenty of food.

Researchers got their first chance to watch wild ferrets up close.

Disease Struck The Last Wild Ferrets Like Lightning

Canine distemper hit the Meeteetse ferrets in 1985, killing them quickly. Their numbers dropped from 130 to fewer than 30 by 1986.

Scientists debated whether to leave them in the wild or bring them into captivity. Making things worse, plague started killing the prairie dogs in the area, taking away the ferrets’ food.

The two problems pushed the species to the edge of extinction.

Scientists Grabbed The Last 18 Survivors Before It Was Too Late

Wildlife officials decided to catch all remaining wild ferrets to save the species. By February 1987, they brought in just 18 ferrets, the entire world population.

These animals became the last hope at Wyoming Game and Fish facilities.

The future of black-footed ferrets hung by a thread, depending on whether these few animals could have babies in captivity. No North American mammal had ever come back from such low numbers.

Seven Ferrets Saved An Entire Species From Oblivion

Only seven of the captured ferrets had babies in captivity. These seven animals became the genetic parents of every black-footed ferret alive today.

The first captive-bred litters arrived in 1987, bringing new hope. The breeding program grew to include facilities across the country, including the National Zoo.

Researchers created new ways to help ferrets reproduce when natural methods failed. Each new birth moved the species further from extinction.

Badlands National Park Offered The Perfect Second Chance

Scientists looked for the best place to release captive-bred ferrets back into the wild. They chose Conata Basin near Badlands National Park with its huge prairie dog colonies spread over thousands of acres.

The National Park Service and Forest Service managed this 64,000-acre area together. Biologists counted prairie dogs to make sure enough food lived there for the ferrets.

The site had the right mix of food, shelter, and safety.

First Ferrets Returned To The Wild After A Decade-Long Absence

Between 1996 and 1999, wildlife teams released 147 captive-bred ferrets into Conata Basin. Each animal wore a radio tracker so scientists could follow it.

Many early ferrets died as they learned to hunt wild prey.

The big breakthrough came when released ferrets started having babies in the wild, creating the first wild-born kits since the 1980s. Counting teams worked through the night to track ferrets and check on breeding.

A Deadly Plague Threatened To Undo All The Progress

Plague hit Conata Basin prairie dog colonies in 2008, creating a new crisis. The disease kills both prairie dogs and ferrets, risking the whole project.

Fleas on prairie dogs carry the plague germs. Scientists came up with a two-part plan: give ferrets plague shots and treat prairie dog holes with bug killer to kill the fleas.

Teams now fight plague every year to keep the population alive.

Badlands Ferrets Spread To Help Other Recovery Sites

The Badlands group grew strong enough to help start new colonies elsewhere. In 2007, the Park Service moved 33 ferrets from Badlands to Wind Cave National Park.

Conata Basin became the model that other sites tried to copy.

Wildlife managers started new ferret groups across western states using ferrets born in the Badlands. They carefully planned moves between sites to keep genetic variety in the growing population.

Half The World’s Wild Ferrets Now Call The Badlands Home

About 120 black-footed ferrets currently live in the Conata Basin and Badlands area.

This represents roughly half of all wild ferrets on the planet, making it the most successful reintroduction site by far.

Scientists continue yearly monitoring through spotlight surveys that catch the green eyeshine of ferrets at night. Teams still dust prairie dog burrows with insecticide every year and vaccinate ferrets against plague.

The population remains stable but requires ongoing management to survive long-term.

Visiting Badlands National Park,South Dakota

Badlands National Park is open 24 hours daily at 25216 Ben Reifel Road in Interior, with a $30 entrance fee for seven days (cards only, no cash).

You can learn about the black-footed ferret recovery program that saved this species from extinction.

While the nocturnal ferrets are rarely seen, visit Roberts Prairie Dog Town on Sage Creek Rim Road to see their habitat and main food source.
