Amazing map offers an inventory of all the trees in the US

The map ... shows the incredible amount of work put in over a six-year period by Josef Kellndorfer and Wayne Walker of the Woods Hole Research Center to create a visualization of the remaining forests in the United States. The pair of researchers saw a need to visualize to the country exactly how much of the natural resource we have left. From the data collected, Robert Simmon built the map with help from U.S. Forest Service and U.S. Geological Survey.
