Trees

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

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

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

Arborists scaled the tree to douse the final flames on August 21.

World’s Tallest Douglas Fir Tree Damaged in Mysterious, Multi-Day Blaze, but It’s Alive After Firefighters Extinguish Flames

The fire started burning on August 16 and only affected a single tree—the historic Doerner Fir in southern Oregon. Authorities are still investigating the cause

Aspen trees are making a comeback at Yellowstone National Park.

Reintroduced Wolves Are Helping Baby Aspen Trees Flourish in Northern Yellowstone for the First Time in 80 Years, Study Suggests

The apex predators, restored to the park in 1995, appear to be keeping the local population of plant-eating elk in check, which allows aspen saplings to grow tall and healthy

A juvenile blacktip reef shark swims in shallow waters by the mangroves in Palau. This image was highly commended in the underwater category.

The winners of the Mangrove Photography Awards shed light on the ecologically valuable but highly threatened coastal ecosystems

A Squamellaria plant grows on a tree in Fiji. As an epiphyte, its roots don't attach to the ground, so it needs to find an alternate source for nutrients rather than the soil.

Enemy Ant Colonies Are Peaceful Roommates in Apartment-Like Plants on Fiji. Scientists Discovered How This Delicate Coexistence Works

New research explores the surprising symbiotic relationship between tubers and different ant species at rainforest heights

Artist Charlie Whinney poses for a photo inside the installation he created around a section of the Sycamore Gap tree.

The Largest Section of the Beloved Sycamore Gap Tree Is Going on Display in England
