But when trees are out of sync, seed loss can increase to over 40%. For decades we have known that beech mast events happen in the year after a warm summer.

A 12-year-old boy was seriously injured when a tree fell onto a vehicle in Londonderry on Friday.

Every year the eastern cottonwood trees in Michigan release their fluffy seeds. The end of June likely marks the end of this process. Here's what to know.

But this week, Covington Flats caught on fire, demonstrating the vulnerability of even the few landscapes deemed viable for Joshua trees in a Joshua Tree National Park redefined by climate change.

Spruce trees that experienced long-term droughts were more resistant to future ones, while pines acclimatized to wet periods were more vulnerable.

Buddhist temples in China are home to trees from dozens of endangered species, a new study shows. Some of them are almost 2,000 years old.

Nearly all the grasses used for lawns are plants that need full sun, so they won’t grow well in a tree’s shade.

The fire is burning in the Covington Flats area of Joshua Tree National Park, an important region where experts say the trees are best suited to survive and reproduce in a warming climate.

Pests are ravaging keystone species like ash, elm, and beech. But researchers are breeding the survivors into more resilient populations.

A new study suggests trees in the forest can access ancient memories and "talk" to each other hours before a solar eclipse.

Learn how trees prepare for a solar eclipse, communicating with each other by synchronizing their bioelectrical signals.

New research reveals older trees use bioelectrical signals to warn forest of solar eclipses, showing advanced tree communication and adaptation.
