> The average age of forests in the United States is younger than it was before European settlement. The greatest diversity is found in the oldest forests, so there may be more forest now, but because it is so young, it is home for fewer animals, plants, insects and other organisms than a fully developed, mature forest ecosystem. It also means that protecting old growth forests is imperative.

It's easy to see land ownership from the satellite images:
Forest service land to the east has been logged, but not quite as extensively as the mixed private and BLM land to the west. The checkerboard pattern is created by that mix of BLM and private land: http://en.wikipedia.org/wiki/Checkerboarding_%28land%29
