A large-scale study proves that trees absorb methane through their bark, with climate benefits at a global scale.
Planting more trees in urban environments is a simple, affordable and effective way to improve health.

Many in the wider community still see sugar gums as risky trees that drop dangerous branches. But there is much to appreciate and admire about Eucalyptus cladocalyx.
Rangelands provide a wealth of ecosystem services and support rural economies while harbouring native biodiversity.

Planting millions of trees in natural grassland is largely ineffective in the battle against global warming because it adds little or no additional carbon storage.

As temperatures and rainfall patterns change, the time that trees produce catkins could change and affect wildlife that rely on catkins for food.
Extreme fires leave forests struggling to recover in a warming world.
Mark Kreider
A new study offers a rare window into the hidden effects of aggressive fire suppression that go beyond fuel accumulation. The practice may even change the course of forest evolution.
