Here's the science behind the amazing colours we should see on British trees this year.
Here's another reason to stop land clearing: it's making Australia hotter and drier.
The invasive mesquite tree has a negative impact on everything from biodiversity to human health. Management programmes are crucial.
Study using tree ring data and climate projections shows that buildup of CO2 will not benefit most northern forests and that growth rates will actually fall.
After some unusually wet years, our landscape and ecosystems have once again returned to poorer conditions that were last experienced during the Millennium Drought.
We'll have to get our priorities in order to protect Australia's wildlife.
Cutting-edge urban foresters argue not only for the intrinsic value of trees but also for the many economic and health benefits.
Over 100 species are dependent on Ash trees for survival – we need to act fast.
If planning decisions properly considered the value of trees in a city, we could have a modern transport system and tree-lined views to enhance the journey.
Land clearing in Queensland has tripled in the past five years.
Six years after Black Saturday, it's worth remembering that heatwaves kill more people than bushfires do, so shade can be a life-saver. But tree cover and shade are not evenly distributed in cities.
As summer rolls on once again you're despairing at a brown lawn. Perhaps you should embrace a shabbier backyard.
Planting more trees in our cities is a good idea, but we need to remember to plan ahead for conditions those trees might encounter when they mature in half a century's time.
There's something in the air that actually has health benefits when you take time to walk among the plants and trees. What that is exactly is still being studied by scientists.
Cities are aiming to increase their tree cover. But there will need to be more than trees to encourage wildlife to return.
We all love a shady courtyard, but it's tough to know just how effective trees are at beating the heat.
The mechanisms are there - but where's the evidence?
Conflicting evidence means it's tough to tell whether trees helping to clear the air, or if green is not as good as we thought.
Mangroves - one of the most important trees - are threatened by rising seas. While these forests can adapt, human development is getting in the way.
2,000 square km of forest have dropped dead in New South Wales, indicating big changes to the environment.
