Well the only problem with the concept is that seedlings don't do well in the shade and the awful invasive blackberries, scotch broom, and poison oak love to fill empty spaces.  I constantly battle the invasives when trying to get the little trees to prosper.  I am not sure that clear cutting is not best for the trees and nature given the invasive plant species that want to take over whenever trees have less than perfect opportunity.  Burning slash is a different matter.
