Sydney turns over a new leaf and says goodbye to much-maligned plane trees

Trees once described as ‘about as much use to our wildlife as concrete posts’ to gradually be phased out in favour of more drought-tolerant plants

The City of Sydney has said it will gradually phase out the use of plane trees across the streets of the city.

Plane trees, which account for almost 10% of the street and park trees across the whole City of Sydney but are the dominant species in some areas, have had their fair share of critics over the years.

Crows and magpies using anti-bird spikes to build nests, researchers find

Dutch study identifies several examples of corvids’ ‘amazing’ ability to adapt to the urban environment

Birds have never shied away from turning human rubbish into nesting materials, but even experts in the field have raised an eyebrow at the latest handiwork to emerge from urban crows and magpies.

Nests recovered from trees in Rotterdam in the Netherlands and Antwerp in Belgium were found to be constructed almost entirely from strips of long metal spikes that are often attached to buildings to deter birds from setting up home on the structures.

The real urban jungle: how ancient societies reimagined what cities could be

They may be vine-smothered ruins today, but the lost cities of the ancient tropics still have a lot to teach us about how to live alongside nature

Visions of “lost cities” in the jungle have consumed western imaginations since Europeans first visited the tropics of Asia, Africa and the Americas. From the Lost City of Z to El Dorado, a thirst for finding ancient civilisations and their treasures in perilous tropical forest settings has driven innumerable ill-fated expeditions. This obsession has seeped into western societies’ popular ideas of tropical forest cities, with overgrown ruins acting as the backdrop for fear, discovery and life-threatening challenges in countless films, novels and video games.

Throughout these depictions runs the idea that all ancient cities and states in tropical forests were doomed to fail. That the most resilient occupants of tropical forests are small villages of poison dart-blowing hunter-gatherers. And that vicious vines and towering trees – or, in the case of The Jungle Book, a boisterous army of monkeys – will inevitably claw any significant human achievement back into the suffocating green whence it came. This idea has been boosted by books and films that focus on the collapse of particularly enigmatic societies such as the Classic Maya. The decaying stone walls, the empty grand structures and the deserted streets of these tropical urban leftovers act as a tragic warning that our own way of life is not as secure as we would like to assume.
