Taking Stock of Recovery

Graduate student Jonathan Batchelor worked with William Ripple, a Distinguished Professor of Forestry, to compare 64 pairs of photos taken over 23 years. Only 6 percent of what was bare soil in the early 1990s remained in that condition when new photos were taken in 2013 and 2014. Fourfold increases in willows and rushes were among the results they reported last year in the journal Environmental Management.
