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.
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.
Large-scale tree-planting projects are politically popular and media-friendly, but without effective planning and long-term management, they can do more harm than good.
Avenues of Honour were planted to remind us of the sacrifice and suffering of our servicemen and women. But as the years wore on, many declined or disappeared.
We may think of plants as passive life forms, but they can cooperate, share resources, send one another warnings, and distance themselves from their communities when survival depends on it.
Advanced techniques allowed our research team to build an open database of billions of individual trees and challenge some common perceptions about vegetation in arid and semi-arid zones.
Scientists are learning trees can emit methane, which could be a big problem for global warming. But a world-first discovery of methane-eating bacteria in paperbark can help moderate this.
As sea levels rise along the Atlantic coast, saltwater is intruding inland, killing trees and turning coastal forests into marshes. Should scientists try to slow the process, or work with it?
Nairobi harbours all the ingredients for zoonotic spillover to occur between animals and people, particularly in the most densely populated areas of the city.
Trees and shrubs in cold-weather climates rely on certain signals, such as temperature and light, to know when to leaf out and bloom. Climate change is scrambling those signals.
