Duh, what a ridiculous statement. You are comparing the culling of differing species of trees to the hunting of the same species of deer. You are straying further from sensibility there fella.
You only think it is ridiculous because you still don't understand the concept of high grading. Maybe if I make the example a bit clearer you may be able to grasp the principle of high grading.
Let's say the stand is 100 year old stand of red ,white and chestnut oak. Now, just for the sake of discussion, let's say 60% of the oak are marketable timber and the other 40% have defects such as too many knots, sway or rot. When the 60% is harvested , the remaining trees will compete with any new seedlings and when those seedlings mature to marketable timber ,less than 50% of the stand will be marketable.
