Yellowstone Is Among the World’s Best Places to See Wild Wolves. Here’s the Story of the Animal Called Both ‘Public Enemy’ and Cultural Icon

A century ago, resident wolves were eliminated from the park. In 1995, biologists brought them back, marking a historic reintroduction of a top carnivore

Beachgoers rested at Lake Lacanau's Moutchic Beach in southwestern France last week, as clouds of smoke rose into the sky from the Gironde wildfire.

Dangerous ‘Fire Clouds’ Are Making France’s Wildfires Even More Destructive

It’s the first time the phenomenon, which is fairly common in North America, has been observed in France

In the Sundarbans, the world's largest mangrove forest, a juvenile Bengal tiger steps from the shadows of mangroves into a tidal creek. This photo was highly commended in the mammals category.

Mangroves Are Key to Coastal Ecosystems. See 20 Breathtaking Photos That Reveal How the Trees Support Wildlife and Face Threats

The Mangrove Photography Awards honor images that show off the beauty—and the fragility—of these valuable intertidal forests

Fruit grows on a native avocado tree in southern Mexico

Ancient Genes Reveal That Big, Bright Avocados Were Carried Through the Americas Thousands of Years Ago

People brought large avocado seeds from South America to Central America, kicking off a burst of diversity for the fruit

Mount Rainier, an active volcano about 60 miles away from Seattle, has sent fast-moving mudflows known as lahars down its slopes before. Scientists just calculated a date for the most recent one.

A Massive Flow of Rock and Mud Tumbled Down Mount Rainier Centuries Ago. Scientists Pinpointed Its Date to Better Understand the Volcano’s Complex Threats

In a recent study, researchers dated a historic lahar called the Electron Mudflow to the summer of 1507, establishing a way to determine when past geologic events around the Puget Sound occurred

Autumn colors frame a calm lake in Central Park as two people row beneath looming skyscrapers.

Verdant Beauty, Wide-Open Spaces, Elegant Architecture: Have a Look at 15 Photos That Show Why Central Park Is the Lifeblood of Manhattan

At the center of the concrete jungle, the green expanse provides New York with a real retreat to nature

A 187-foot-tall dipterocarp tree

Tall Trees Were Thought to Be More Vulnerable to Drought. But These Towering Plants in Southeast Asia Have Adapted to Move Water Efficiently

A new study found that enormous dipterocarp trees have special adaptations to transport water up to their highest limbs, challenging the assumption that they would more easily succumb to dry conditions

Located in Sherwood Forest, the Major Oak failed to produce leaves this spring and is now presumed dead.

Major Oak, the 1,200-Year-Old Tree with Ties to the Robin Hood Legend, Is Presumed Dead After Failing to Produce Leaves

The legendary bandit who stole from the rich and gave to the poor is said to have used the massive tree as a hideout while running from the sheriff of Nottingham

By combining ecological data-gathering with philosophical contemplation, Leopold bridged the art and science of conservation.

America at 250: The Revolutionary Spark

In the Early 1900s, a Young Ecologist Shot a Wolf and Watched the Life Leave Its Eyes. That Changed His Position on Conservation

Aldo Leopold’s writing reconsidered the place of humans in the natural world and challenged people to be less conquerors of the land and more citizens of it

The sycamore tree before it was felled in 2023

How Do You Honor a Fallen Tree? In England, a Sound Sculpture Will Broadcast the ‘Voice’ of a Beloved Sycamore Felled Near Hadrian’s Wall

“The People’s Tree” will also incorporate the tree’s wood and archive recordings from the public in a series of community artworks

This Socorro dove recently hatched at the San Diego Zoo Safari Park. Conservationists have been undertaking a decades-long effort to breed the extinct-in-the-wild species and one day reintroduce it to its native Socorro Island in Mexico.

New, Rare Dove Hatchlings Are a ‘Source of Hope’ for the Extinct-in-the-Wild Birds and a Step Forward in the Ambitious Project to Save Them

The Socorro dove has not been recorded in the wild since 1972, but that could change within only a few years, conservationists say, thanks to a long-term reintroduction effort

To estimate the wolf population, researchers observed animals from planes, followed tracks on the ground and inspected kill sites this year.

Wolves Are Thriving at Michigan’s Isle Royale National Park, Reaching Their Highest Numbers in Almost 50 Years, New Data Suggests

Scientists estimate that 37 of the animals now roam the rugged archipelago, which has contributed to the dwindling moose population. But the predator-prey ratio might be stabilizing

Study author Gregory Bonito collects truffles in Australia. 

Australia Has a Surprisingly Successful Truffle Industry. This New Study Could Explain Why

Researchers examined hundreds of soil samples to uncover why the expensive fungi are thriving in the country

SERC ecologist Jamie Pullen inserts a tool called a dibble bar into the ground to create a hole for a sapling.

The Planet Needs Prosperous Forests. These Scientists Are Planting More Than 33,000 Trees to Find the Perfect Species Blends

Forests provide myriad benefits, including timber, wildlife attraction, local cooling and climate resilience. At the Smithsonian Environmental Research Center, ecologists are testing which tree combinations might create flourishing woodlands

Yasuyuki Aono kept track of bloom dates for Yamazakura cherry trees in Kyoto.

In Japan, a New Steward for 1,200 Years of Cherry Blossom Data Has Been Found, Sustaining a Climate Change Research Project

Climate scientist Yasuyuki Aono, who died last summer, learned to read ancient Japanese script to compile records on peak bloom dating back to the ninth century C.E.

A young living root bridge, barely a decade old, is seen from the deck of a much older root bridge on the same riverbed. Five months after I shot this photograph, monsoon rains triggered a landslide that sent boulders crashing into the younger bridge. It absorbed the impact and shielded the older bridge downstream.

In One of the Wettest Places on the Planet, Indigenous People Build Bridges and Ladders Out of Living Tree Roots

For hundreds of years, Khasi and Jaintia people in Meghalaya, India, have woven the roots of Indian rubber trees into structures that help them navigate flooded areas

The fire-loving fungus Geopyxis, seen here in 2022, after California’s Caldor Fire, has distinctive brown cups with white rims.

These Charcoal-Eating Fungi Flourish After Fires. Uncovering Their Genetic Secrets Could Help Rebuild Burned Ecosystems

Mycologists cultivated fungi they found in post-wildfire landscapes to understand the evolutionary traits behind their ability to thrive in the wake of flames

In laboratory studies, coronae emit a faint blue light from the tips of spruce needles. In nature, ambient light drowns out this glow, so researchers used a special camera to detect invisible, ultraviolet emissions. 

Treetops Emit Ultraviolet Sparkles During Thunderstorms. Researchers Just Filmed It in Nature for the First Time

The weather events probably cause the air around leaves to produce weak electrical discharges

Archaeologists Are Finally Unraveling the Secrets of the Shipwreck Discovered 20 Feet Below the Streets of Manhattan

Researchers are opening a new investigation into the timbers, which may have once belonged to the “Tyger,” a Dutch trading vessel that sank in 1613

Through gene-editing, researchers in the field of synthetic biology hope to make endangered species more resilient against disease or climate change and protect human health, among other goals.

Three Stunning Ways Biologists Aim to Edit Animal and Plant Genes to Fight Diseases and Extinction

The strategy, known as synthetic biology, is gaining momentum globally as a conservation tool and human health solution, despite attracting some critics
