The most recent USDA Forest Service data confirms that United States forestland is roughly as abundant today as it was 100 years ago. The Forest Service’s Resource Planning Act 2007 (RPA data) reveals both state and regional increases in forestland across the country.
Among the key findings in the report (http://www.fia.fs.fed.us/program-features/rpa/default.asp) are:
Ø There are 750 million acres of forestland in the U.S. today, about the same as in 1907.
Ø 11 states had increases of over 25 percent over the last century, and nine had increases of over 30 percent.
Ø Overall, forestland in the northern U.S. has increased by almost 30 percent. read more
