The Endangered Species Act turns 50 this December. Often called 鈥渢he pit bull of environmental statutes,鈥 the ESA has given federal protection to nearly听2,000 animals and plants.
It has also drawn critics who claim it takes away property rights and hurts economic development.
After half a century of recovery efforts, only a few hundred species have got delisted. On the other hand, the whole world faces a biodiversity crisis, with more than 44,000 species threatened with extinction. And the ESA has been the international model law for how to save what the world has left.
Some of the ESA鈥檚 biggest struggles have happened in Montana, including fights over gray wolves, grizzly bears, bull trout and sage grouse. As the law reaches its 50-year anniversary, a group of Lee Montana reporters scanned the state to see how it鈥檚 working and what its future holds.

Since it was signed by President Richard Nixon on December 28, 1973, the ESA has protected more than 2,000 animals and plants, becoming one of Earth鈥檚 most far-reaching laws.
About this story: The听Endangered Species Act听has become one of the Earth鈥檚 most far-reaching laws. It passed Congress with only 12 dissenting votes across both the House and Senate. Of the 1,663 animals and plants placed on its list since then, about 100 have gone extinct. Another 54 have been declared recovered and delisted. Critics of the ESA point to that 鈥渄elisted鈥 number and say recovering only 3% of the total in half a century is a failure. Proponents see that in reverse: Nearly all the species protected by the law have remained on the landscape.听
A century ago, we stocked non-native trout throughout national parks. Now native species like cutthroat trout must be transplanted in experimental habitats if they're to survive through this decade.
About this story:听In a new tactic to听help recover threatened and endangered species, the U.S. Fish and Wildlife Service has authorized expanded use of experimental populations to recover animals protected under the Endangered Species Act. The rule, published in the Federal Register earlier this summer, allows at-risk animals to be transplanted in suitable habitats where they didn鈥檛 exist before. Such a project is underway at Glacier National Park's听Gunsight Lake, where biologists have started the long process of transforming the waterbody into a refuge for future cutthroat and bull trout.
鈥淭he Endangered Species Act only protects that relatively small number of species that are right on the precipice of disappearing."
About this story:听A critical difference between federal species conservation and state-led efforts is that the ESA was designed to yank an imperiled species back from the brink before it disappears entirely from its historic range 鈥 at least in all or part of the U.S. But state-led efforts like Montana鈥檚 grouse reintroduction are meant to make sure a species gets what it needs while it's still around. If Montana has its way, sharp-tailed grouse will never approach that brink.听
Guard dogs and range riders have protected people against bears for millennia. They may offer solutions for co-existing with grizzlies as the recovered trouble-maker of the West nears ESA delisting.听
About this story:听Grizzly bears gained federal protection in 1975 shortly after the ESA was ratified in 1973. A half-century later, the bears are widely considered to be recovered in the Lower 48 states. But they remain listed under the ESA, while leaders in Montana, Idaho and Wyoming have demanded the bears be turned over to state management. Learning how to co-exist may be key, and some of the most efficient tools used today to keep predators away from livestock, grain and humans are the same ones that have been utilized for thousands of years 鈥 dogs and听shepherds.
Would Arctic grayling in the Big Hole River benefit from federal protections afforded by being listed as an endangered or threatened species under the ESA? Some stakeholders don't think so.
About this story:听Legal quests for listing the Arctic grayling began听more than 30 years ago. They have proceeded in fits and starts, like a grayling struggling to migrate upstream when flow in Montana's Big Hole River drops toward a trickle. The Fish and Wildlife Service has rejected several attempts to list the fish, only to be reversed in court. Stakeholders have long butted heads over whether听the river-dwelling population of Arctic grayling in the Big Hole River would听 truly benefit from federal protections.
Getting Yellowstone National Park bison protected under the ESA might break "the stranglehold Montana has placed on recovering wild bison." But those aren't the only bison.
About this story: The restoration of bison in North America is largely hailed as a conservation success story. Now, the Fish and Wildlife Service鈥檚 review of Yellowstone bison for possible listing under the ESA is being undertaken as Yellowstone National Park considers an overhaul of its bison management plan. The National Park Service has offered three alternatives, the most aggressive of which calls for keeping the population between 3,500 to 5,000 animals using hunting and culling as well as live bison transfers to cap the population.
Montana Untamed:听Often called 鈥渢he pit-bull of environmental statutes,鈥 the ESA has given federal protection to nearly 2,000 animals and plants.
Listen to our podcast: Montana Untamed is created in partnership across five Montana newsrooms听鈥 the Billings Gazette, Helena Independent Record, Missoulian, Montana Standard and Ravalli Republic. On this episode, host Thom Bridge and project lead Rob Chaney unpack the Endangered Species Act and why reporters chose to pursue the series. What has the law accomplished over the past 50 years, how has it played out in Montana and what can the world expect in the decades to come?听

It's unusual to see Park Service personnel, or anyone, in Yellowstone National Park carrying a weapon. But this summer a crew used an air rifle to shoot darts to collect DNA samples from bison. The sampling is a small part of the work being conducted as the animals are considered for protection under the Endangered Species Act.

The ancient bison, Bison antiquus, was taller, had longer horns, and was 25% more massive than living American bison (Bison bison). It was roughly 7.5 feet tall and 15 feet long, weighing approximately 3,500 pounds. Bison had bone horn cores on their skull that served as a base for a longer horn made of keratin, the protein that makes up our fingernails. The span of the horns of Bison antiquus was approximately 3 feet.
