From the NASA EO story: " Political change in eastern Europe and Russia has left its mark on forests. A research team led by Peter Potapov of the University of Maryland analyzed 52,539 images collected by Landsat satellites between 1985 and 2012. “Forests generally recovered quickly,” noted Potapov. “Only 12 percent of the areas that experienced forest loss prior to 1995 had not yet recovered by 2012.”
