Mono culture in any environment is a mistake. Look at cities which planted only one species of trees on their streets. A blight enters the non diverse area and wipes out all the trees in short order. Do you not think that the same can and will happen to wildlife. We had a major die off of white tailed deer last winter. 100% die off in a small area. Biologist think it burned out because it was so rapid. Had it taken a few weeks to kill instead of days the devastation would have been much greater in scale. think about 90+% die off in an area that covers several states. Major risk of this modern mono culture and short sited game management.
The cry to let nature take its course has a certain simple minded appeal. Virgin forest were not the same from end to end and the Native Americans burned areas to increase regrowth and edge cover. Problem is that no managed system will ever turn back the clocks as many key species are gone forever. Ever see a American Chestnut tree that was mature. Been gone for a hundred years and not coming back. Heavy handed manipulation will only go off in a series of wrong directions with little long term improvement for game or even man.
