With a bit of sensible planning, you can retain plants close to your home without creating a huge bushfire risk.
The drought has pushed many trees to the brink, and whole stands are now dying. The ecological consequences are huge.
Inner Melbourne alone has lost 2,000 street trees to major developments within a decade. Losing tree cover makes it even more difficult for our cities to cope with an increasingly tough climate.
In a warming world, trees can play a major role in keeping cities and your home cool. If you plan it right, they can even save you money and protect your home from bushfires.
A tree-killing beetle that invaded South Africa two years ago and wreaked havoc in the country's towns and cities still hasn't been declared an emergency plant pest.
Although China's tree-planting efforts have increased carbon sequestration for climate mitigation and protected the soil from erosion, they have also led to drastic water shortages.
The red gum, or Eucalyptus camaldulensis Dehnh.
Understanding invasive trees' ecology and history is crucial to developing effective management practices.
A holm oak: the longer Cosimo spends in the trees, the greater his identification with the natural world.
The protagonist of Calvino’s novel takes to the trees in a fit of adolescent rebellion and never comes down. Yet from his self-imposed isolation he remains enviably connected and committed to his community.

If you're craving that freshly-cut tree smell, shop early and don't be too choosy.
A mast year can be a squirrel’s dream come true.
Masting is what biologists call the pattern of trees for miles around synchronizing to all produce lots of seeds – or very few. Why and how do they get on schedule?
Turning a street tree into timber is much more respectful and useful than mulching it all.
City trees are often short-lived and many others get cut down in their prime. Turning them into mulch both wastes timber and releases stored carbon. A wood rescue program creates a more fitting legacy.
Sir Godfrey Kneller, 1687
John Evelyn's 1664 work 'Sylva' called for a mass tree planting campaign.
What can your vacation pix tell scientists?
To untangle the relationship between climate change, fall foliage and national park visitors, researchers are asking tourists to check their old photo albums for snapshots that could hold valuable data.
What’s happening with the trees that stay green?
Many deciduous trees put on a dazzling fall foliage display. But coniferous evergreens hold on to their needles and stay green. A biologist breaks down these different survival strategies.
From happier and healthier residents to more resilient buildings – green roofs offer significant benefits to cities.
Where’s the shade? Trees are not an immediate or whole answer to keeping cool.
Trees and the shade they provide are one of the best ways of cooling cities. But they also present challenges that are best resolved by managing this shared resource as part of an urban commons.
The Amazon will take a lifetime to recover from this year's fires – if it ever does.
African elephant in Kruger national park, South Africa.
In large ecosystems, managing elephant populations so they don't exceed a certain threshold number is arbitrary.
Remains of a 365m-year-old forest of extinct lycopsid trees has been found in China.
Natural forest systems are far better at adapting to change conditions than young, degraded or plantation forests.
Forget eyecatching headlines about planting millions of new trees – natural mature forests are far better at storing carbon.
