Hope on the Prairie: The Black-Footed Ferret Returns to Colorado

In many respects, hope defines our work at The Nature Conservancy.  In turn, our work fuels that hope.

Take, for instance, my recent experience helping reintroduce black-footed ferrets to their historic home on eastern Colorado’s prairie.

It’s likely that ferrets have been absent from eastern Colorado for more than 100 years.

Entirely dependent on prairie dogs for survival, ferrets were largely the unintended victim of widespread prairie dog extermination campaigns and introduced diseases.

By 1980, the species was believed to be extinct, lost before it had ever really been understood or appreciated.

But, in 1981, the first glimmer of hope faintly appeared in Meeteetse, Wyoming when a single remnant population was discovered by a rancher who reported it to the U.S. Fish and Wildlife Service.

Rampant disease forced their removal from the wild, but a captive breeding program began with the last 18 surviving individuals.  At six facilities around the country, biologists carefully breed the ferrets to maximize genetic diversity.

Training programs put young ferrets through prairie dog hunting “boot camps;” if they learn to hunt, they’ll be eligible for release.  The breeding and training programs have been successful; hundreds of ferrets are now available for release, awaiting appropriate habitats and the elusive welcome mat for an endangered species. Having cleared those hurdles, they’ve been released at sites from South Dakota to Arizona, returning a key predator to prairie dog towns.

Now, in Colorado,, 35 ferrets arrived at the Walker Ranch, unaware of all that had to happen to give them this chance to go home.

Welcome Home, Ferrets

I’ve worked with Gary and Georgia Walker for years to help conserve their family ranch, a 64,00-acre slice of Colorado prairie. So far, we’ve successfully placed a conservation easement on nearly 22,000 acres of the ranch.

As long as I’ve known them, Gary and Georgia Walker have wanted to reintroduce black-footed ferrets to their ranch, but a longstanding culture of fear and mistrust surrounding endangered species issues has long frustrated their desire.

After nearly 20 years of work, the Walkers and the U.S. Fish and Wildlife Service cleared the last hurdles to a ferret release in Colorado.

Last week, a diverse group ranging from the Conservancy to federal biologists to farmers and ranchers, finally watched as 35 black-footed ferrets arrived on the Walker Ranch from a ferret breeding and training facility.

As masked faces peered at us from stacked pet carriers, it was awe inspiring to realize that these animals represented nearly double their species’ entire global population less than 30 years before.

The Release

Releasing the ferrets was simple and straightforward: take a carrier to an active prairie dog burrow (there are nearly 10,000 acres of prairie dogs on the Walker Ranch), position it at the entrance hole, open the door and wait for the ferret to cross the threshold.

And in my case, though not part of the standard protocol, I wished them good luck and Godspeed.

Watching from a distance, I was mesmerized by the spectacle of ferrets simply being ferrets, the way they’re supposed to be, in a place they haven’t been in a century or more.

At one point, a brave lone prairie dog approached and seemed to lock eyes with one of the ferrets.

Although that prairie dog had never encountered a ferret before, something about that steady gaze and serpentine movement caused a light to go off, and eons of instinct took hold, causing the prairie dog to run for its life.

Words of Hope

I am grateful my 9-year-old daughter and 6-year-old son were able to join me for the release.

I wanted them to see and experience it all. They saw the ferrets and listened to the speeches, including Gary Walker’s well-stated logic for why he, as a cattle rancher, saw practical and economic benefit to having black-footed ferrets on his land.

But it was later in the afternoon, after the crowd had gone and we were helping with the release of a few more ferrets, that my son noticed the real reason that countless people dedicate years of their lives to conservation.

Gary, the practical businessman rancher, had opened the door on the carrier of a reluctant ferret at the entrance to a burrow.

With a mile-wide smile and a gentle, quiet voice, my son overheard him saying to the ferret “Go on, punkin’.  It’s ok, everything’s ok.”

At the end of the day, that ferret didn’t represent economic practicality to my friend Gary.

It was a living, breathing reflection of the wonder and the beauty of our natural world, a beauty too long diminished by its absence.

And it was a reflection of hope.

Hope comes from seeing good people work hard and succeed. Hope comes from seeing people come together from wildly divergent backgrounds and worldviews.

Hope comes from seeing those people create something beautiful. . . together.

  1. Having a wonderful moment of vicarious pride and joy through you, Matt. Thanks to the Walkers for being persistent and thanks to you, Matt, on behalf of all of us desk-bound nature lovers for helping the vision become a reality. This is a wonderfully, sublime “good” thing.

  2. When I read of the release of the Black-Footed ferrets in Colorado

    When I read about the release of 35 Black-footed ferrets on the Walker Ranch in Colorado
    it brought tears to my eyes. Tears of gratitude that there are people
    like Gary and Georgia Walker and members of the Nature Conservancy still here on this earth.God bless you all and especially your thirty five new tenants who have to be happiest
    Black-footed ferrets that ever existed.

  3. Wow. Moments of true connection with Nature are rare and wonderful. Matt, you shared the story so beautifully. Thanks to you and the Walkers for walking each step of this inspiring journey.

  4. Hope. Large and small reasons for hope. That’s why I join TNC more than 20 years ago.

  5. Prairie dogs, Black footed ferrets, and the eco system in which they exist are one of the reasons I became a member. Too often they and their eco systems are heartlessly destroyed. This is a bright light in the ignorance of those who do not understand the importance of these beautiful creatures.

  6. YOU GUYS ROCK BIG TIME, I have a ferret and they are the best and you guys bring tears of pure happiness to my eyes seeing that there is a chance to save our wild North America ferret from the hell the white man put them through and to save them from going extinct, I love all you guys for what you are all doing PLEASE DO NOT STOP UNTIL IT IS ACCOMPLISHED PLEASE AND THANK YOU FROM THE BOTTOM OF MY HEART.

  7. The Thunder Basin National Grasslands are close being ready for black-footed ferret reintroduction. Resistance from a few ranchers and Governor Mead’s office are holding up progress. It is wonderful to see the Walkers demonstrate an appreciation for the wildlife that roamed their ranch for millennia prior to domestic cattle importation from Europe and around world. It is only a matter of time before the dogma that prevents reintroduction efforts will die off.

    Good work TNC and kudos to the Walkers and all who have worked diligently to return our prairies to a more naturally healthy condition.

  8. Spotted a lack footed Ferret.. (young) on the east side of Colorado Springs 8/8/2014. Beautiful Animal/ Could not had been more than 3 or 4 feet away and very curious.

  9. This is great! My question is… how do we get some ferrets in Southern Colorado? We’re virtually overrun with prairie dogs in Northern Huerfano county.The elimination of natural predators has created an explosion here.

  10. Thank you for your work and blog. On November 26, 2015, Thanksgiving day, how appropriate, while skiing beautiful Wolf Creek ski resort in southwest Colorado, my husband and I saw snow moving……up hill. Alas, 20 ft away, I got a good look at what seemed like nothing other than the most exquisite ferret ever, all white except for its coal black tipped tail. Two runs later we saw another one, not so close up, and it was darker, not white like the first one, antic-ally scurrying across a 200 ft wide ski run.
    A definite highlight for us to be sure, not to mention everything else that day as thanksgiving snow fell gently.
    God Bless,
    Diane and Craig Munson

  11. Given the fact that the black-footed ferrets depend upon prairie dogs as their single food source, I wonder if you are aware of the proposed Colorado House Bill 16-1010 which was introduced 1/13/2016 “Destructive Rodent Pest Release Authorization Requirements” It presents one more roadblock thrown up against the relocation of prairie dog colonies. Currently, in northern Colorado, the general attitude is to eradicate the entire species of prairie dogs. Here in Longmont, thousands have been poisoned in the last 2 months. Where is the logic to reintroduce one species then kill its food source? I need not tell you the importance of this animal. I hope your organization can protest this bill.

  12. Over the weekend we spotted a black footed ferret in monument, co heading toward a field from the Home Depot off Jackson Creek Parkway. We took a pic of the little guy. May 30, 2016

  13. Can someone please help save the Urban Prairie Dogs that are being destroyed by the thousands by RTD light Rail and overdevelopment by Denver and Aurora, and Boulder Colorado? Wildlands Defense Colorado is trying but help would be appreciated,I’m sure.
