Crown  - The crown of the trees is the area, if you stand back from the tree, that has leaves.  That's the crown.  Its the area which produce leaves or needles.  We can reduce the crown by limiting height or we can do a crown elevation in which the crown is raised.  Raised meaning that the distance from the ground to the first leaves is elevated.  Crown reduction is best done while the tree is young.  A young tree is one that would be 100% dynamic mass.  A young tree can have as much as 90% of the stem removed which is done in nurseries when the cut the trunk to about 6".  A mature tree should have symplastless, symplast dying and diseased branches removed only. 

See "3 Crown Theory".
