Study From The U.S. Geological Survey Finds Tree’s Growth Rates Do Not Slow As They Age

A long-held belief about old trees has been uprooted. A new study from the U.S. Geological Survey finds that trees' growth rates do not slow as they get older and larger – instead, they keep putting on mass along with their years. Study lead author Nate Stephenson is a forest ecologist with the USGS. He says if people did the same, we would weigh well over a ton by retirement. For trees, the finding changes what we know about how they store carbon, and has implications for forest management.
Stephenson says old, large trees are better at storing and absorbing carbon from the atmosphere.
