Many urban canopies across U.S. cities are dominated by only a handful of tree types, putting them at risk of being wiped out by an insect or disease.

Seven of the most common forest trees in Europe have been shown to be able to shelter their genetic diversity from major shifts in environmental conditions. This is despite their ranges having ...

Old-growth forests are made up of the tallest, oldest trees, that host established ecosystems and, the Forest Service found, can hold important social and cultural meaning.

The U.S. Forest Service just finished its first ever count of mature and old-growth forests that sit on national land — and it found that combined, they cover an area larger than the state of ...

Harvesting 5–10% of the trees does temporarily reduce the total amount of carbon stored in the forest, but these stocks recover quickly if damage to young trees and soils is kept to a minimum.

But climate change won’t be stopped for decades at best, and trees and forests are already confronting it. Scientists are working on solutions to help them adapt. Here we look at four of them. 1.

Positive citation bias and overinterpreted results lead to misinformation on common mycorrhizal networks in forests. Nature Ecology & Evolution, 2023; DOI: 10.1038/s41559-023-01986-1 ...

The number of red spruce, one of Maine’s most common and valuable trees, is likely to decline by 50% by 2100, according to the U.S. Forest Service’s climate change tree atlas, a modeling tool ...
