Wildlife & land conservation

This archive tracks meaningful progress in protecting wildlife and preserving land — from habitat restoration and endangered species recoveries to new protected areas and conservation policy wins. These stories focus on what’s working, grounded in evidence and reported with care.

African elephant walking through dense forest in Tanzania wildlife corridor

Elephants are now using Tanzania’s first legally protected wildlife corridor

Wildlife corridors are protected strips of land that let animals move between habitats, and Tanzania now has its first legally designated one. The wildlife corridor crosses the Kilombero Valley, linking Nyerere National Park to Udzungwa Mountains National Park. Communities chose the route, and 368 landowners gave up small plots. Villagers have planted about 100,000 native trees along it. But elephants have avoided a planned road underpass, and nearby construction could weaken the route.

Vivid blue morpho butterfly resting on a green leaf in Mount Mabu's protected butterfly forest

Mozambique protects 23,000 acres of Mount Mabu “butterfly forest”

The Mount Mabu forest draws hundreds of butterflies to its 5,600-foot summit every October and November, a mating behavior called hilltopping. Scientists have recorded more than 200 kinds there, plus species found nowhere else, including a cobalt-blue butterfly known from a single specimen. Local people have long kept the forest standing, and the rules for using it are still unwritten, so how much use it will allow remains open.

Delacour's langur with black-and-white fur perched among green leafy branches

Vietnam creates 7,900-acre refuge for critically endangered Delacour’s langurs

Delacour’s langur, a monkey found only in the limestone hills of northern Vietnam, now has legal cover for one of its last strongholds. Scientists found the Kim Bang group in 2016 with about 40 animals, and state media counted 128 last year. About 4,500 acres are strictly protected and another 3,400 are set for restoration. But no buffer zone has been proposed, and quarrying and poaching still threaten the forest.

Once extinct in the wild, more than 600 scimitar-horned oryx now roam Chad

The scimitar-horned oryx, a pale, long-horned Sahara antelope, has become a test case for whether captive-bred animals can relearn life in the wild. Researchers tracking the herd released in Chad since 2016 see early signs the animals are rebuilding social bonds and migration knowledge lost when wild herds vanished, and the same approach now helps other endangered antelope like the addax. Still, the species remains Endangered, and conservationists say securing its future is unfinished work.

Sweeping view of Brazil's Cerrado savanna landscape with trees and mesa in background

180+ organizations join massive effort to restore 4.4M acres of Brazil’s Cerrado

The Cerrado gets a fraction of the attention the Amazon does, despite being the world’s most biodiverse savanna — and losing more than half its native vegetation already. The coalition working to change that has built real infrastructure from scratch: seed banks, nurseries, trained technicians, land agreements. A separate Cerrado finance fund has quadrupled its investment in a year, growing from 32 to 122 participating farms. Neither effort has finished the job. But real capacity and real capital are both now flowing toward saving it.

A lone bison stands on a grassy hillside under a blue sky

Bison return to Mexican state of Coahuila for first time in 200 years

Cuatrociénegas is one of North America’s strangest landscapes: 324 square miles of spring-fed pools, gypsum dunes, and diverse plant life. What it lacked was a large grazer. Forty-eight bison, most transferred from the Rancho El Uno herd in Chihuahua’s Janos Biosphere Reserve, now break up compacted soil, carry seeds in their coats, and carve shallow wallows — restarting processes that stopped generations ago. That herd descends from 23 bison the U.S. sent from Wind Cave National Park in 2009. Mexico still lists bison as at risk, and with no predators here, managing the herd’s growth is an open question.

Black bear walking along a rural road through forested southern landscape

Black bear population rebounds across the American South after near collapse

Bears are not mountain animals — they thrive in swamps, pine stands, and farm-field margins, which is why the Mississippi floodplain was once their heartland. Mississippi had an estimated 12 bears left when it protected them in 1932; Arkansas, down to 40 or 50 in the 1950s, restocked with bears trucked in from Minnesota and Manitoba, now holds roughly 5,000. Louisiana’s bears left the federal threatened list in 2016. Females breed slowly and young males wander hundreds of miles, so the return is measured in decades. Conflict with farms and suburbs is the next problem to solve.

Colombia landscape and water

Colombia protects 42% of its territory, creating the Amazon’s largest reserve

Colombia’s Amazon protection sets a permanent ceiling on extraction across 186,500 square miles — the largest extraction-free zone in the basin, in a forest storing 6.5 gigatons of carbon and supplying water to 670 million people. The resolution invokes a rarely used legal mechanism to block new mining and fossil fuel contracts, while existing projects run to expiry. Indigenous-governed lands, retaining 99.5% of their forest cover, account for more than half the protected area. Whether the protection holds remains uncertain, as the incoming president has signaled plans to revive oil exploration and expand fracking.

Wild Przewalski’s horses born in Kazakhstan for the first time in 200 years

Przewalski’s horses — the only living wild relatives of domestic horses — have taken a fragile but real step back toward their ancestral home on the Central Asian steppe. Two foals born at Kazakhstan’s Altyn Dala State Nature Reserve show that a herd translocated from European zoos is beginning to reproduce independently, a threshold conservationists consider proof of genuine adaptation. With only 24 horses currently in Kazakhstan against a target of roughly 40, the goal of a self-sustaining population remains ahead — yet this milestone joins a growing pattern of coordinated reintroductions quietly reversing extinctions that once seemed permanent.

Spider monkeys climbing through dense rainforest canopy in Costa Rica

Costa Rica requires wildlife crossings on all new and existing roads

Costa Rica’s economy depends on the wildlife its own roads have long put at risk — sloths and monkeys struck by cars, habitat split in two, coastal crabs unable to reach the sea to lay their eggs. Lawmakers voted unanimously to make wildlife crossings a legal requirement, built into road planning from the earliest stage rather than added as an afterthought. Citizens can now submit their own evidence to force retrofits on existing highways already causing harm. Conservationists call it a meaningful shift away from decorative warning signs, which do little to slow drivers, toward structures proven to actually save lives.
