Rewilding: The Last Truly Wild Horses Return Home

The Przewalski’s horse has rebounded from near extinction. There were once only 12 of these pony-sized wild horses remaining in the entire world. Even just a few years ago, all the existing Przewalski’s horses lived in captivity, and the species was listed by the IUCN as “extinct in the wild.”

These little horses are the last truly wild horse species in the world. The American mustang and other well-known “wild horses” are actually feral rather than wild — they descended from domesticated horses that got free and chose to live in the wild rather than go back to captivity.

The Przewalski’s horses are not out of the woods. There are concerns about their survival in the age of climate change should Mongolia begin to experience unusually harsh winters. And it is possible that they may interbreed with feral horses, diluting their bloodline so that they would no longer be a distinct species. But the Przewalski’s horse seems to have avoided the biggest threat to species recovering from near-extinction — a lack of genetic diversity leading to inbreeding and health problems.

ReWilding Endangered Black-Footed Ferrets in Colorado

More good news from northern Colorado! I recently posted a story about the return of wild bison to Colorado for the first time in over a century. Now, 30 black-footed ferrets, an endangered species once so rare that only 18 of them remained in the wild, have been returned to a 1,300 acre prairie dog colony north of Fort Collins.

They will join the over 500 other ferrets that have been reintroduced into the wild since they almost went extinct in the 1960s. They are still critically endangered, but they are on the rebound!

This National Geographic video is a short and sweet story about these very ferrets. Thanks to Gordon Eaglesham for sharing it on his blog.

Wild Bison Return to Colorado

This is my favorite kind of story — when wildlife are allowed to return to habitats they used to live in before being hunted nearly to extinction. Last week, on National Bison Day, 10 bison were reintroduced to northern Colorado, where they haven’t roamed free for more than 150 years.

The National Wildlife Federation worked to bring brucellosis-free bison to a 1000-acre parcel of open space owned by the city of Fort Collins and Larimer County. Brucellosis is a bacterial disease that can cause female bison to miscarry. Because it is possibly transmissible to domestic cattle, ranchers have long fought the reintroduction of bison in areas where their cattle might come into contact with them. The 10 bison released in Colorado last week were bred using a new technique that should guarantee they are free of brucellosis. The eventual goal is to have a herd of hundreds of bison roaming about 10,000 acres. Bison from this large herd could go on to repopulate other areas or provide fresh bloodlines to other bison herds.

Only a few bison were left in the U.S after the herds of 30 million were reduced to just a few individuals by the late 1800s. Ten bison is just a small start, but someday large herds could roam parts of Colorado again.
