Fair enough . Ive just been quickly scanning the posts with out much thought. I go back to what I understand the original question to be . We do shoot mature underperforming bucks with zero belief that it makes any difference genetically. However 1) Gives folks something to shoot. 2) Assures the buck removed will not kill one we hope to get to old age 3) One less mouth on the habitat. 4) Do not know what impact this has but a dead deer will not be breeding. 5) Age and nutrition ! Period !
All said though for most folks on smaller properties in reality they are habitat mgrs. hoping to influence deer behavior , not deer herd managers. That takes scale or circumstance.
