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

Volunteers have played a vital role in SERC's Functional Forests project. They've helped plant trees, put up deer fencing and mapped the tree locations with bamboo stakes, among other duties.

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

New Research

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

The larvae feed on the leaves of elm trees in a distinctive zigzag pattern.

This Invasive Wasp Is Wreaking Havoc on Elms in North America—and the Damage May Soon Spread to Other Trees

Elm zigzag sawflies can munch on plants beyond their preferred elm trees when foliage isn’t available, a new study suggests

Curator Richard Hill notes Carr’s unusual choice to orient her nature paintings vertically, as in Cedar (left, 1942) and Red Cedar (1931). “It really is a portrait of a tree.”

This Canadian Painter Found Her Muse in the Verdant Trees of British Columbia

Emily Carr took her brushes out of the gardens and into the rainforest to capture her local landscape in ways “beloved and also fraught”

A dead tree stands with its bare, white trunk and branches in contrast to the greenery around it.

What’s Killing These Oak Trees in the Midwest? Conservationists Believe Drifting Herbicides Are to Blame

When Illinois landowners noticed tree deaths and diseases on their properties ramp up in 2017, they suspected industrial agriculture. A survey found herbicides in 90 percent of tree tissues

A savanna in western Maharashtra, India

Ancient Literature Suggests India’s Savannas Are Much Older Than Previously Thought

Plant species mentioned in texts from the past 800 years hint the wooded grasslands of western India have been there since ancient times, pushing back on the narrative that they are remnants of long-gone forests

Nineteen-year-olds Marta Bernardino and Sebastião Mendonça are developing a robot capable of reaching and reforesting areas where humans have been unable to.

Two College Students Are Building a Robot to Replant Burned Forests

Marta Bernardino and Sebastião Mendonça invented Trovador, a four-legged, A.I.-powered robot that can plant trees in hard-to-reach, wildfire-damaged terrain

Navigating based on natural signs, writes Tristan Gooley, “sharpens our powers of observation, deduction and prediction.”

It’s Almost Impossible for Tristan Gooley to Get Lost. That’s One Reason He Has Millions of Followers

The British adventurer has crossed the Atlantic solo in a plane and a boat. Now he reads tree leaves, puddles and moss to get his bearings

Researchers studied rainforests in northeastern Australia. These wet rainforests are very dense, and their canopies help cool down their ecosystems and store large amounts of carbon.

Australian Rainforests Become the First to Emit More Carbon Than They Absorb

A new analysis finds tropical forests in Australia are not taking in enough carbon dioxide to keep up with the emissions from their decaying trunks, holding possible implications for global ecosystems

New Research

The Amazon’s Trees Might Be More Resilient to Climate Change Than We Thought

A team of nearly 100 researchers found the average tree size in the massive rainforest has increased by more than 3 percent per decade since the 1970s

The slice was taken from an area of the trunk roughly three feet above the ground.

By Counting Growth Rings, Researchers Solve the Mystery of the Sycamore Gap Tree’s Age

A new analysis shows that the historic tree was at least 100 to 120 years old in September 2023, when two men illegally chopped it down
