OK, so you work with wood every day, and you know that they didn't just grow in your backyard (well, maybe they did...) But where, exactly, does your wood come from?
The following image was produced by Josef Kellndorfer and Wayne Walker of the Woods Hole Research Center (WHRC), with the assistance of the U.S. Forest Service and U.S. Geological Survey. It depicts an inventory of aboveground woody biomass for the United States. Darker colours indicate higher concentrations, taller and more robust forest growth.
For me, the most shocking was the dearth of growth in the central states.
