CARBON BUDGET OF UNITED STATES FORESTS

Q: What is the current carbon flux of forests in the U.S.?

A: Our carbon flux estimates for coterminous U.S. forests are:

Soils 113
Forest floor 14
Understory 2
Trees 82
Total 211

Live flux includes understory and trees. Dead flux includes forest floor and soil. A positive number indicates that the forest is sequestering more carbon than it is emitting to the atmosphere.
