Forest fires: North America’s boreal forests are burning a lot, but less than 150 years ago

North America’s boreal forests have been burning a lot, probably more and more over the past 60 years. Yet the long-term trend indicates that they are burning less than they were 150 years ago.

Wolf culls change hunting habits and help caribou conservation

Woodland caribou populations are on the decline because human activity changes their habitat and exposes them to predation by wolves. But changing wolves’ hunting habits may protect the caribou.

COP26 deforestation deal key to slowing climate change, but Canada must tackle issues of carbon accounting and industry

The pledge to end deforestation holds great potential, but Canada has some work ahead if it is to make meaningful progress on the new goal and stop ongoing forest and carbon loss.

How wildfires affect climate change — and vice versa

Recent wildfire seasons have been worsened by climate change. But wildfires also lead to additional climate warming when they release carbon dioxide to the atmosphere.

As extreme fires transform Alaska’s boreal forest, deciduous trees put a brake on carbon loss and how fast the forest burns

A new study finds more deciduous trees like aspen are growing in after severe fires in the region, and that has some unexpected impacts.

How scientists are restoring boreal peatlands to help keep carbon in the ground

Peatlands store more soil carbon than any other terrestrial ecosystem, including tropical forests. But they have been heavily exploited and damaged. Now, scientists are working to restore them.

How plants can help clean up oilsands tailing ponds

A new nature-based approach to managing oilsands tailings shows promise in the lab and may soon be tested in the field.

More frequent fires could dramatically alter boreal forests and emit more carbon

The boreal forest is being reshaped by wildfire. As climate change intensifies wildfire activity, the boreal forest will likely become a carbon source.
