The remoteness and small size of old-growth boreal trees should not make us forget their high ecological importance and the many threats they face.
Logging over the past two centuries has had a major impact on Québec’s forests. The traces it has left will guide the adoption of sustainable forest management techniques.
North America’s boreal forests have been burning a lot, probably more and more over the past 60 years. Yet the long-term trend indicates that they are burning less than they were 150 years ago.
Rising temperatures mean longer, earlier pollen seasons, but a bigger problem is what more carbon dioxide will do to the amount of pollen being released.
Even in death, a tree helps others live.
Red tingle forests in south-western Australia have the lowest fire risk when they’ve not been subjected to prescribed burning. New research explains why
Many beloved wildflowers bloom in early spring, while trees are still bare and the flowers have access to sunlight. Climate change is throwing trees and wildflowers out of sync.
Protecting old and mature trees is the simplest and least expensive way to pull carbon out of the atmosphere – but proposed logging projects threaten mature stands across the US.
Calling the Amazon “the lungs of the world” overlooks the forest’s vital role in the water cycle.
They’re beautiful in bloom, but Callery pear trees crowd out native plants and turn productive open land into woody thickets.
Canada’s boreal forest is affected by global warming, climate change and the frequency of forest fires.
Over 50 fire ecologists across the Western U.S. took an unprecedented look at how forests in thousands of locations are recovering from fire in a changing climate. The results were alarming.
New research finds that some common houseplants take in nutrients from outside the soil.
The mountain ash dominates as the tallest species of tree, but they did not win tree with the biggest girth.
Plath’s sublime nature poetry deserves widespread appreciation for its unfettered joy and deep attunement to the natural world.
From pine trees to camphor laurel and even the Cootamundra wattle, trees can be weeds too.
South Africa needs to integrate urban green spaces as part of valuable infrastructure and provide framework for their sustainability.
Tu BiShvat has religious roots, but early Zionists embraced the day in new, more secular ways.
In 2015, 6,700 premature deaths were caused by urban heat – this can be reduced by a third by planting more trees.
