This is the first time researchers have calculated the amount of carbon released from the world’s decaying wood. They found insects play an enormous role.
Biological control strategies curb pests using other species that attack the invader. A biologist explains why it can take more than a decade to develop an effective biological control program.
The Tongass National Forest in Alaska, a focus of political battles over old-growth logging and road-building in forests for decades, has received new protection from the Biden administration.
More than 40 fire scientists and forest ecologists in the US and Canada teamed up to investigate why wildfires are getting more extreme. Climate change is part of the problem, but there’s more.
They overlook a vast body of evidence that crown fire – the most extreme type of fire behaviour in which tree canopies burn - is more likely in logged native forests.
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.
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?
