Every day of the year, conservation is at the center of the inspiration and work at Cheyenne Mountain Zoo. As 2018 comes to a close, we’re reflecting on some of CMZoo’s conservation contributions this year. We hope you’ll be inspired to take action, big or small, to join us in the important work of conserving endangered species for generations to come.

One way to support wildlife conservation (while learning a lot and having a great time) is by visiting the Zoo! Through CMZoo’s Quarters for Conservation program, guests contribute to conservation around the world, simply by visiting the Zoo. For each paid admission to the Zoo, 75¢ is directly allocated for conservation programs including safeguarding African vultures, rescuing frogs in Panama, protecting wild orangutans, restoring the population of black-footed ferrets, saving wild giraffe, increasing the population of endangered Wyoming toads and helping to protect African elephants and rhinoceroses. Each year, Quarters for Conservation allows Cheyenne Mountain Zoo to contribute $500,000 to these conservation efforts and more.

Operation Twiga

Giraffe conservation was given a generous boost from many helping hands when Operation Twiga continued in 2018 with Operation Twiga III in Uganda. Cheyenne Mountain Zoo staff and other concerned conservationists took part in translocating endangered Nubian giraffe to a safer location, where they could establish new herds and maintain the important genetics of their subspecies. Additionally, the operation generated more critical health data which will feed research that helps conservationists understand disease management and threats facing all giraffe in the wild.

During Operation Twiga III, the team was able to capture and move a total of 14 giraffe from Murchison Falls National Park, where oil drilling is set to begin, to their new home in Kidepo Valley National Park.

Tsavo Trust

Cheyenne Mountain Zoo’s Quarters for Conservation has allowed us to send more support to Tsavo Trust – a field-based non-profit organization in Africa that uses aerial surveillance and on-the-ground field efforts to protect wildlife in Tsavo National Park, the largest national park in Kenya. The organization was founded to help protect the last of the “big tuskers,” which are likely the last viable genetic pool of African elephants with tusks weighing more than 100 pounds each. The park is also home to a number of black rhino sanctuaries established by the Kenya Wildlife Service (KSW) and supported by the Zoological Society of London. The black rhino is critically endangered, due primarily to illegal poaching for their horns.

In partnership with the Kratt Foundation in August, CMZoo sent $53,333 to support ongoing anti-poaching aerial surveillance efforts, bringing the total contribution to $145,000. These funds also helped complete the construction of Tsavo Trust on-site staff housing. This donation means Tsavo Trust can continue to monitor and protect roughly 16,000 miles of land that is vital to the survival of these endangered species.

Black footed-ferrets

In mid-September, four kits and four adult black-footed ferrets (BFF) were moved to a preconditioning center outside of Fort Collins, Colo., where biologists observe the ferrets to ensure they can hunt, avoid predators and shelter themselves to survive without human intervention and continue to increase the endangered species’ population when they’re introduced into the wild.

Since the 1981 discovery of a small population of BFFs in Meeteetse, Wyoming, conservationists launched a black-footed ferret recovery plan which continues to increase the population. Numbers fluctuate, but recent reports estimate 350 BFFs are thriving in the wild, thanks to this program.

Protecting wild orangutans

Palm oil is widely used in many products, ranging from food to cosmetics, but is grown in just a few countries throughout the world. This includes much of Indonesia and Malaysia, which are home to orangutans and other unique species. As the demand for palm oil has increased globally, Indonesia’s and Malaysia’s natural rainforest has decreased in size as a result of unsustainable slash-and-burn clearing to make way for more palm oil crops. This loss of habitat threatens the survival of many native species.

CMZoo is committed to educating the public about the use of sustainable palm oil, providing guidance about which companies are members of the Roundtable on Sustainable Palm Oil, which means they are committed to using sustainably produced palm oil in their products. In September, CMZoo’s palm oil team traveled to the Association of Zoos and Aquariums annual conference to share knowledge and resources. CMZoo’s palm oil app has been named as a reliable guide for information on sustainable palm oil in many publications and forums, including most recently by National Geographic.

African vultures

Vulture conservation has been a focus at Cheyenne Mountain Zoo for nearly a decade, and while strides have been made toward protecting them, this critically important species still hovers on the brink of extinction. They need our help more than ever.

This year, the Association of Zoos & Aquariums voted to include African vultures as one of their SAFE (Saving Animals From Extinction) projects, thereby creating an opportunity for more united conservation efforts. Currently, 12 zoos across the country are committed to partnering with African conservation organizations in order to address the African vulture population crisis. As part of this group, Cheyenne Mountain Zoo supports Vulpro in their efforts to re-introduce African vultures to their wild habitat through one of our Quarters for Conservation legacy projects.

In addition, these birds have been part of our annual membership vote the past three years. We are proud to say that Cheyenne Mountain Zoo has donated nearly $67,000 to vulture conservation to date.

Wyoming toads

CMZoo made favorable strides in the management of endangered Wyoming toads in spring and early summer as CMZ experienced a robust egg-laying season, followed by the release of hundreds of year-old toads into the wild. Wyoming toads are currently listed as “extinct in the wild” by The IUCN Red List of Threatened Species.

On May 30, our CMZoo staff released more than 200 head start toads into the wetlands of the Laramie Basin of Wyoming. At the same time, 856 head-start toads were released by Saratoga National Fish Hatchery and around 50 were released by the Leadville National Fish Hatchery.

Head-start toads develop from tadpoles hatched the previous year. This year’s breeding season at CMZ began June 4 when, after hibernating for 35 days, 11 pairs of adult Wyoming toads were put together in the breeding center. Nine of the pairs produced fertile egg strands, which included 14,822 eggs!

The work continues, as we grow our conservation programs and educate the public about how they can help support efforts to protect wild species.

Four kits and four adult black-footed ferrets (BFF) are one step closer to life in the wild, thanks to the Cheyenne Mountain Zoo conservation team. In mid-September, the ferrets were moved to a preconditioning center outside of Fort Collins, Colo., where they’ll spend about 35 days in a semi-controlled environment. During this phase, biologists observe the ferrets to ensure they can hunt, avoid predators and shelter themselves to survive without human intervention and continue to increase the endangered species’ population when they’re introduced into the wild.

With their black and white bandit-mask markings, inquisitive expressions and fluffy fur so similar to their adorable domestic cousins, it’s easy to assume the black-footed ferret is another one of North America’s plentiful wild small mammals. But, this is the only ferret species naturally found in the wild on this continent – and it was recently thought to be extinct.

During the western frontier exploration in the early 1800s, cargo ships from Europe and Asia brought sylvatic plague to North America. The spread of this disease, combined with poisoning and eradication programs led by newly settled farmers and ranchers, who saw prairie dogs as pests, drastically reduced the prairie dog population. Because prairie dogs are black-footed ferrets’ main food source, the BFFs’ population declined dramatically. By the 1980s, black-footed ferrets were thought to be extinct.

Since the 1981 discovery of a small population of BFFs in Meeteetse, Wyoming, conservationists launched a black-footed ferret recovery plan which continues to increase the population. Numbers fluctuate, but recent reports estimate 350 BFFs are thriving in the wild, thanks to this program.

Preconditioning is the final program stage for these born-to-be-wild individuals, and Jeff Baughman, CMZoo field conservation coordinator, makes it his life’s work to prepare them to thrive without relying on humans.


“We limit the human interaction as much as we can,” Baughman said. “We feed them and keep them healthy and clean while they’re with us, but other than that, we try not to let them hear or see us very much. Wild animals need a healthy fear of humans, so they’re not tempted to get close.”

From weekly lighting adjustments to reproductive monitoring and only four breeding opportunities (once per year, for four years) to pair a compatible couple to conceive, the intricacies of black-footed ferret breeding success are meticulously managed by the CMZoo conservation team. Cheyenne Mountain Zoo is one of only five zoos in the world supporting the black-footed ferret species survival plan, with partners at Toronto Zoo, Louisville Zoo, Phoenix Zoo and Smithsonian Conservation and Biology Institute along with the USFWS National Black Footed Ferret Breeding and Conservation Center just outside of Fort Collins, Colo.

“Some people wonder why we invest so much energy to saving this species,” Baughman said. “They’re not just cute; they’re vital in helping secure healthy prairie ecosystems. BFFs are predatory prey, so their environmental role is to help control prairie dog populations while occasionally being a food source to owls, coyotes and badgers. BFF reintroduction sites are managed for plague which keeps the prairie dog populations healthy. This safeguards all of the other prairie species that rely on prairie dogs (a keystone species) as well. Black-footed ferrets are rare and important because they serve the ecosystem up and down.”

The black-footed ferrets at Cheyenne Mountain Zoo are being born and raised for genetic assurance of the Species Survival Plan population with about half of the offspring being allocated for release into the wild.

Although the BFF conservation area isn’t open to the public at CMZoo, visitors can still experience one of these endangered, beautiful creatures at The Loft. In 2015 after the age of four (when BFFs’ reproduction windows close), Sylvester came to the Zoo from the National Black-footed Ferret Conservation Center as he was a great candidate for being an educational ambassador.

Cheyenne Mountain Zoo is committed to continued support of wildlife conservation efforts like the black-footed ferret Species Survival Plan. Through its Quarters for Conservation program, you can help by simply visiting the Zoo. For each paid admission to the Zoo, 75¢ is directly allocated for conservation programs just like this one. Each membership also helps support conservation efforts.


Every expectant mother wants good lighting for her big moment, but for black-footed ferrets, lighting is absolutely critical to optimum breeding.

CMZoo Conservation Coordinator Jeff Baughman utilizes lighting cycles, lots of cell testing and a solid timetable to successfully breed the endangered small mammals.

Currently, Baughman averages about 20 to 30 black footed-ferret kits per breeding cycle. The ferrets are a little behind schedule right now, but Baughman has his fingers crossed that the females due from the beginning through the end of July will provide healthy kits. Baughman and staff have a whelping success rate of 57% – an impressive statistic that has helped bring this species back from the brink of extinction.

With their little black masks and feet, adorable ears and fluffy fur, it’s easy to assume the black-footed ferret is another one of North America’s plentiful small mammals, when in reality this apex predator is the only ferret species found on this continent.

During the western frontier exploration in the early 1800s, prairie dogs were identified as pests and large-scale poisoning and eradication programs continued into the 1930s. The prairie dog is the black-footed ferrets’ main prey, so, sadly, this behavior and belief also led to the decline of black-footed ferret.

By the early 1980s, black-footed ferrets were considered extinct – until they were rediscovered in 1981 on a ranch near Meeteetse, Wyoming. After studying this small population for a few years, scientists discovered they were extremely susceptible to diseases like canine distemper and the sylvatic plague. To effectively save the species, 24 ferrets were taken into human care.

Since then, a black-footed ferret Species Survival Plan (SSP) was written, enacted and has been continued by a handful of Association of Zoos & Aquariums-accredited (AZA) organizations along with U.S. Fish & Wildlife Service. Cheyenne Mountain Zoo is proud to be one of those zoos and is currently in the process of monitoring the whelping of seven out of 11 female black-footed ferrets at the on-site Zoo’s conservation center.

Associate Zoo Veterinarian Dr. Eric Klaphake explained the veterinary aspect of successful breeding begins early on in the process. CMZoo’s vet and conservation staff will start doing health checkups on breeding age males and females in the fall. This includes checking body condition and teeth health.

Baughman utilizes light cycling to stimulate breeding behaviors in the ferrets. He operates the lights at around 90 foot candles. A foot candle is a measurement of light intensity and is defined as the illuminance on a one-square-foot surface from a uniform source of light. This means it gets pretty bright during breeding cycles. In the fall, Baughman begins the light cycle at a low luminescence to stimulate breeding behaviors in the males. By late spring and early summer, the light level has increased to 15 hours of light per day to speed up the estrus cycle in females.

“These light cycles recreate what would naturally be happening in the wild and essentially make it feel and look like the long days of summer,” Dr. Klaphake said. “The ferrets need to cycle down and back up. The light starts this cascading of hormones up to the brain and back down to the organs to initiate breeding activity.”

To ensure optimum breeding opportunities, conservation staff will test the viability and health of male ferrets through sperm samples and then examine reproductive cytology of the females so that the best breeding partners can be matched up.

“We will test to evaluate the quality and number of sperm cells, their morphology and motility,” Dr. Klaphake said. Negative testing can indication reproductive challenges and if so, we can choose not to cycle those animals into the breeding pool, or we can contact the National Black-Footed Ferret Conservation Center up near the Colorado/Wyoming border and talk about exchanging for different animals.”

The ferrets’ gestation period is only around 50 to 60 days. After birth, the kits are monitored by camera. Conservation and vet staff try to stay as hands-off as possible, but will interact with the kits to assess their growth and weight, try to determine the sex of the kits and monitor both mom and babies for any health concerns.

“The first four days are hands-off,” Baughman said. “At 21 days, we’ll start weighing and determining sex, then at 26 to 30 days, we will introduce meat. At 37 days, they open their eyes. Then, at 50 to 90 days, they are given live prey and separated from mom to begin the pre-conditioning process. This is important because they need to be able to be effective hunters as they’re being reintroduced back into the wild.”

Different kits progress to different stages, says Dr. Klaphake.

“Some might go into the wild ferret ‘bootcamp’ at the conservation center, others might to be sent to other facilities to be part of breeding programs and others might go to zoos to be animal ambassadors or conservation program animals,” he said.

“Bootcamp” is a pre-conditioning stage where conservation staff introduce and test ferrets slated to be released on their hunting and predation skills.

To get as many ferrets as possible to that stage, Baughman needs the remaining females to birth successfully. Part of the complication comes from the fact the ferrets are not artificially inseminated – their breeding is all natural. Though it’s not an exact science, Baughman is fairly confident that if all the components are on track – lighting, testing and time – the formula will again prove successful.

“It’s like a Tetris game, where all the pieces and parts have to fit into place,” he said.
