National Research Highlights

Global Forests Sequester One-third of Annual Fossil Fuel Emissions, Much More Than Previously Thought (2011)
Forested land plays a much larger role in removing carbon from the atmosphere than was previously thought, according to Forest Service scientists working with an international team of scientists. One of the key findings in the study is that global forests have annually removed 2.4 billion tons of carbon (8.8 billion tons of carbon dioxide) from the atmosphere, about one-third of annual fossil fuel emissions for the period of 1990-2007.


How to Build a Better Map of Tree Biomass (2014)
A logical way to validate biomass maps derived from remotely sensed data is to validate them with independent ground inventory estimates, but integration of the two systems is not without challenges. Forest Service scientists compared maps derived from Light Detection and Ranging (LIDAR) to Forest Inventory and Analysis (FIA) estimates in the fragmented forests of Maryland, leading to recommendations about how to improve their agreement.


Past and Prospective Carbon Stocks Assessed in Forests of Northern Wisconsin (2014)
Forest Service scientists and cooperators assessed past and prospective carbon stocks for 4.5 million hectares (about 11 million acres) of forest land in northern Wisconsin and analyzed the effects of disturbance and management. Over the last decade, carbon stocks of northern Wisconsin forests have been increasing and they found that there is potential to increase stocking on the land by allowing more of the forested area to reach older age classes or by increasing growth rates through improving forest management.
