Western White Pine

Detailed Description

A western white pine (Pinus monticola) in Kings Canyon National Park, Calif., towers over USGS ecologist Nathan Stephenson.

Scientists analyzed data from 403 species of trees from around the world -- including western white pine (Pinus monticola), pictured here -- and learned that in general, a tree's growth continues to accelerate as it ages. This finding reverses previous assumptions, and suggests that large old trees play an unexpectedly dynamic role in removing carbon from the atmosphere.
