A study by Oregon State University researchers has identified forests in the western United States that should be preserved for their potential to mitigate climate change through carbon sequestration, as well as to enhance biodiversity.
Those forests are mainly along the Pacific coast and in the Cascade Range, with pockets of them in the northern Rocky Mountains as well. Not logging those forests would be the carbon dioxide equivalent of halting eight years’ worth of fossil fuel burning in the western lower 48, the scientists found, noting that making land stewardship a higher societal priority is crucial for altering climate change trajectory.
The findings, published in Ecological Applications, are important because capping global temperature increases at 1.5 degrees Celsius above pre-industrial levels, as called for in the 2016 Paris Agreement, would maintain substantial proportions of ecosystems while also benefiting economies and human health, scientists say.
“The greater frequency and intensity of extreme events such as wildfires have adversely affected terrestrial ecosystems,” said study co-author Beverly Law, professor of forest ecosystems and society in the OSU College of Forestry. “Although climate change is impacting forests in many regions, other regions are expected to have low vulnerability to fires, insects and drought in the future.”
