When using the google earth tool, the closer you zoom in the better you can understand what is happening. Start with a “green” area and watch what happens over time. Then start with “brown” area (most likely a recent harvest site) and watch what happens over time. What you will see is a constantly evolving mosaic of harvest, replanting and regrowth. That is forestry in a nutshell. The story would be even more compelling if the timeframe were longer.
