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.

John Evelyn’s 1664 work ‘Sylva’ called for a mass tree planting campaign.
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.
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.
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.
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.
Forget eyecatching headlines about planting millions of new trees – natural mature forests are far better at storing carbon.
Cities around Australia have plans to increase their green space, but new research shows not all green spaces are equal. Good tree cover is better than grassed areas for residents’ mental health.
Ecological literacy is needed to guide global tree planting initiatives to avoid damaging some ecosystems.
Thirty tree species make up more than half of Australia’s urban forests. Some won’t survive climate change, so cities must plant a more diverse mix of the right species to preserve their tree cover.
Hot weather kills more Americans yearly on average than floods, tornadoes or hurricanes. Three scholars explain how cities can prepare and help residents stay cool.
Red gums connect the continental fringes of Australia with its arid heart, marching along waterways.
The species which surround a tree in a forest make up the character of its neighbourhood. Good neighbours can make forests resilient to climate change.
White cedar grows across Asia and Australia, as a hardy and resilient deciduous.
Mulga is an Aussie icon: hardy, adaptable, and absolutely everywhere.
The leaves, when boiled, can be eaten like spinach. The seeds can be roasted for a coffee substitute, and the pulp can be fermented to make beer.
Thousands of years of history tells the same story over and over: you ignore soil at your peril.
