A new study shows that ash tree populations are not growing fast enough to replace the trees killed by ash borer larvae

Rare woodlands are vital stores of biodiversity but are under threat of being lost entirely

Global maps of places where people and forests coexist show that an estimated 1.6 billion people live within 5 kilometers of a forest. The assessment, based on data from 2000 and 2012 and published September 18 in the journal One Earth, showed that of these 1.6 billion "forest-proximate people," 64.5 percent were located in tropical countries, and 71.3 percent lived in countries classified as low or middle income by the World Bank.

This is a story about frustration, about watching the West burn when you fully understand why it’s burning — and understand why it did not need to be this bad.

Australia's rainforest-dwelling stinging trees are notoriously painful, and Queensland researchers say they now know why.

This fire season is yet another sign that we can't wait any longer to fix our planet

The horrific fires of 2020 are just a preview. No matter what we do, two to four times as much land area will soon burn annually in the West.

Trees are growing faster because of rising CO2 levels and temperatures, but also dying younger, meaning existing forests will store less carbon than forecast and climate change will be worse than expected

Rise in carbon capture as global warming speeds growth of forests would be negated by earlier deaths, say scientists

Though feared destroyed, most of the ancient trees at Big Basin Redwoods State Park withstood the blaze.

A study published earlier this year showed that peatlands in Canada are drying up and that fires there will become more common in the future.

Earth's oldest trees have been rooted for millennia. Why they can live so long is explained in a new review.

Investing in halting deforestation and limiting the wildlife trade could be a cost-effective way to reduce the risk of pandemics, a new analysis finds.

The architect Charles Bello has spent the past 52 years restoring forests from logging and protecting the land on his 400-acre ranch in Northern California. Here's what he's learned along the way.

Hackney has a more diverse population of trees than any borough in London.

When Guatemala created a major reserve 30 years ago, environmentalists complained that too much land was entrusted to local people and not converted to parks. Now, the parks have been overrun by ranches linked to drug traffickers, while the community-run lands are well preserved.

Wall Street investment funds took control of Oregon’s private forests. Now, wealthy timber corporations reap the benefits of tax cuts that have cost rural counties billions.

Not by themselves, but the Archangel Ancient Tree Archive is out to show how they can help.

One researcher calls it "botanical sexism."

Tim Brodribb has been measuring all the different ways global warming kills trees for the past 20 years. With a microphone, he says, you can hear them take their last labored breaths. During blistering heat waves and droughts, air bubbles invade their delicate, watery veins, cracking them open with an audible pop. And special cameras can film the moment their drying leaves split open in a lightning bolt pattern, disrupting photosynthesis.
