    I wish they had displayed some older ones that show how it changes an ecosystem 50 or 100+ years later. When replanting trees after a wildfire we use a similar technique, digging a little semicircular trench around the downhill side with some rocks to pool water, but with none of that succession planting they do in the Sahel. It seems like it'd be so cool if it does actually result in a multi-layered forest immediately feeding itself.
