Light gap
In ecology, a light gap is a break in the forest canopy or similar barrier that allows young plants to grow where they would be otherwise inhibited by the lack of light reaching the seedbed. Light Gaps form predominantly when a tree falls, and thus produces an opening in the forest canopy.
