In January 2021, Argentina released three jaguars into the Iberá Wetlands, a region where the species had been extinct for 70 years. Scientists gave the project a decade to prove itself. Four years later, the population had grown well beyond expectations, with births occurring in the wild for the first time in generations.The wetlands span 13,000 square kilometers in Corrientes Province in northea…

Thirty years have passed since bison were first reintroduced to the long-grass prairies, an ecosystem that was once thriving but had remained dormant for over a century. Since then, bison numbers

Thirty years have passed since bison were first reintroduced to the long-grass prairies, an ecosystem that was once thriving but had remained dormant for over a century. Since then, bison numbers have grown without any signs of slowing down. Long ago, herds of Europe’s largest land mammal moved by the thousands through ancient forests, shaping meadows, spreading seeds across entire regions, and ca…

Paul Watson, the Canadian environmental activist and founder of the Sea Shepherd Conservation Society, had an Interpol red notice against him permanently canceled in mid-2025. The decision by Interpol’s File Control Commission ended more than a decade of restricted movement for Watson, who had been sought by Japan over anti-whaling confrontations in Antarctic waters. Watson described the developme…

The Devil’s Hole pupfish was among the first species listed under the Endangered Species Preservation Act in 1967, which later became the Endangered Species Act. The fish is found nowhere else on

The Devil’s Hole pupfish was among the first species listed under the Endangered Species Preservation Act in 1967, which later became the Endangered Species Act. The fish is found nowhere else on Earth except in a single geothermal pool in the Nevada desert, within a deep fissure known as Devil’s Hole.In June 1965, a weighted rope was lowered into the water at Devil’s Hole and kept descending in t…

Two men pleaded guilty to killing a rare pupfish in Devil’s Hole, a geothermal pool in Death Valley National Park. They entered the protected area in 2016, fired at least ten rounds, left beer cans

Two men pleaded guilty to killing a rare pupfish in Devil’s Hole, a geothermal pool in Death Valley National Park. They entered the protected area in 2016, fired at least ten rounds, left beer cans behind, and one swam in the pool. The incident caused damage that biologists said likely destroyed eggs and disrupted breeding on the only spawning shelf the species has.This is not the first time the s…

Thirty years have passed since European bison were reintroduced to the tall-grass prairies, an ecosystem that had been dormant for over a century. The population has since grown steadily.

Thirty years have passed since European bison were reintroduced to the tall-grass prairies, an ecosystem that had been dormant for over a century. The population has since grown steadily. Historically, herds of Europe’s largest land mammal moved by the thousands through ancient forests, shaping meadows, dispersing seeds, and creating trails that other species learned to follow. Centuries of huntin…

In the summer of 1980, a cargo plane landed on a gravel airstrip in Canada’s Northwest Territories, near the Liard River Valley. On board were 28 wood bison, the largest land animals in the Western

In the summer of 1980, a cargo plane landed on a gravel airstrip in Canada’s Northwest Territories, near the Liard River Valley. On board were 28 wood bison, the largest land animals in the Western Hemisphere. The species had been absent from this part of the country for more than a century. The animals were released onto ground their kind had not occupied since before the late 1800s.The immediate…

In the early 2000s, Florida began a large-scale effort to restore the Picaune Strand, a 55,000-acre swamp in the southwestern part of the state. Decades earlier, the land had been drained and divided

In the early 2000s, Florida began a large-scale effort to restore the Picaune Strand, a 55,000-acre swamp in the southwestern part of the state. Decades earlier, the land had been drained and divided into a grid of roads and canals by a real estate company that sold it as dry lots. The restoration project was designed to reverse that damage and create one of the last viable habitats for the endang…

In the swamps of southern Florida in the early 1990s, wildlife biologists were monitoring a population of Florida panthers that appeared to be in terminal decline. By the mid-1990s, fewer than 30 of the animals were believed to remain in the wild, and projections suggested the subspecies could disappear entirely within about four decades. In January 1995, eight female cougars were brought from Tex…
