Most of the earthworms in the US Northeast and upper Midwest are nonnative species. Scientists are finding increasing evidence that invasive worms and invasive plants may help each other.
A new survey has identified millions of hectares of forest in dryland areas, a finding that boosts the total global forest cover by 9% and has significant consequences for carbon budgets.
A new report calls U.S. forests an undervalued asset for slowing climate change. It warns that they are being degraded by logging for wood, paper and fuel, particularly in the Southeast.
Forests are valuable for many uses, including timber, clean water, wildlife habitat and recreation. Stresses on U.S. forests include wildfires, pest invasions and development of private lands.
Combining new technologies, including Global Forest Watch, a Forest Monitoring App and Participatory 3D Modelling, brings out traditional knowledge of the elders.
Study using tree ring data and climate projections shows that buildup of CO2 will not benefit most northern forests and that growth rates will actually fall.
It’s important to close roads from further vehicle use after the end of logging operations. But these roads ought to be re-opened when the next phase of logging takes place in each area of forest.
A review of more than 40 years of wildfire activity in the western U.S. demonstrates the potent effect drier, warming spring seasons, due to climate change, is having on wildfires.

Yes, climate change is creating conditions for the extraordinary wildfires near Fort McMurray, Alberta, but El Niño played a bigger role, says atmospheric scientist.
Science was instrumental in working out how to clear brigalow forest to make way for farming in the 20th century. Now it’s trying to bring these iconic forests back.
