My property was an oak savanna that became a woodland ultimately comprised of a large proportion of buckthorn and boxelders weed trees which I've recently removed. The older trees were large spreading oaks. There are also quite a few woodland grown oaks as well as black cherry, ash, and elm, that have often reached the canopy but with more slender trunks and minimal lower branches. Culling the weed trees has created more space and let a lot more light in. My question is, now with more space and light, should I expect these thinner, and in some cases scrawny trees (especially but not only the black cherry) to fill out even though they are already canopy height or, if that were the objective, would I need a new crop?
