BSK,what are you trying to accomplish
As JJS pointed out, I am trying to get more sunlight onto the ground. I recently had several 3-5 acre patches of timber thinned, but due to low market value, many trees in those designated harvest areas were not cut. So I am killing those trees in place instead of cutting them down (much less labor involved). And the purpose is to increase sunlight on the ground which will increase early successional plant growth as deer food and eventually increase thick growth that will provide escape cover.
Most of what I am killing are huge beech trees. A single old beech tree can have a canopy covering a 1/4 of an acre. Killing that one tree will open up a big hole in the leaf canopy and allow sunlight onto the ground and ensuing regrowth.
I was also killing out groves of 5-8 adjacent hickory and butternut trees to produce holes in the canopy.
Although I'm certainly not killing all or most of them, the species I'm targeting are beech, hickory, butternut, elm, sourwood, and a few maple. I am protecting oaks other than mountain chestnut oaks (which I have far too many of).
