Historical comparison

Caption

These two images show the same landscape in Washington state – the top taken in 1936 and the bottom in 2012. The top photo shows a landscape with less tree cover, maintained naturally through frequent historical wildfires. The bottom photo shows how forest cover has densified and expanded in the same area under policies of fire exclusion.
