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.
Scientists are urging the Biden administration to protect mature US forests as a climate change strategy, starting with the Tongass National Forest in Alaska.
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.
Without enough water, trees can develop embolisms, similar to blockages in human blood vessels, and they’re more likely to die from drought or fires.
A better understanding of the science behind falling trees – followed by informed action – will help keep us safe and ensure trees continue to provide their many benefits.
Using remnants of fossilized trees, scientists and an artist figured out what the forest looked like long before humans existed.
When a big old tree dies or is cut down, even if we plant a new one we might have to wait hundreds of years before it provides a good possum house.
Children need to connect with Australia’s bountiful variety of trees. New picture books are helping them to do so.
