The world is a much better place for the extra carbon being absorbed by forests, but it can never entirely offset emissions.
Hooking trees up to internet-connected sensors provides a new way to study how they interact with the environment - and how the public interacts with their tweets.
Wild sandalwood populations in Australia have been slowly collapsing for decades. New research found the Western Australian government has been warned repeatedly for a century.
When a plant is stressed, it mobilises its resources and often converts its starch reserves back to sugar. As soon as this happens, the stressed plant becomes sweeter than its healthier neighbours.
A growing number of countries and companies have pledged to reach net-zero emissions by 2050 or earlier. But there’s a catch – they still plan to keep emitting greenhouse gases.
A staggering 17,500 tree species are at risk of dying out.
Towering trees in African tropical mountain forests are a vital, overlooked carbon store threatened by deforestation.
Biological control strategies curb pests using other species that attack the invader. A biologist explains why it can take more than a decade to develop an effective biological control program.
Spring is rapidly approaching and many birds are hunting for the best nesting sites. Competition is fierce — especially for species that nest in tree hollows.
Planting a massive number of trees can help slow climate change, but it is only part of the solution.

The diverse plant collections in botanical gardens increase the chance of pests and pathogens encountering suitable hosts and becoming invasive.
The audio version of an in-depth article on why there aren’t enough trees to offset society’s carbon emissions – and there never will be.
Hundreds of computer simulations point to a few best strategies for keeping homes safe from fire in a warming climate.
The Tongass National Forest in Alaska, a focus of political battles over old-growth logging and road-building in forests for decades, has received new protection from the Biden administration.
As a tree scientist who works with urban trees, I can assure you some large, old trees are well worth leaving alone, even you find them annoying sometimes.
Sacred trees are a cornerstone of our national identity. They transcend simple economics and sit at the centre of the sacred — sentinels in ceremony, birthing and burials.
Despite their good intentions, cities rarely have the full set of skills and capabilities to turn their plans into a reality. Our research looks at what needs to change.
Climate change is causing jacarandas to flower earlier. If this trend continues, they could be at risk of flowering when it’s too cold and become dormant.
It’s no coincidence that more books about trees are popping up. There is an air of desperation in new books by Peter Wohllben, Janine Burke and others.
