I don't mind answering that question at all Mozark. On my 100 acres place where I have the native grasses, the change was obvious the next year when the grasses started making good cover. I had some good bucks to filter in from the surrounding areas quickly. Good cover trumps everything else in my opinion for old bucks. Before we put in the NWSGs, my dad was farming cattle there, and my fields were fescue. So, adding cover really made a difference quickly. Food plots and fruit trees are kind of like icing on the cake. They help, but cover is king.
At my 20 acre place about all I can do over there is hinge cut unless I want to take the 7 acre field out of soybeans/corn. Since I don't have equipment over there to manage a field, I choose to just keep it in crops rented out to a farmer. But when i started hinge cutting over there and making the woods thicker, I could see an improvement on camera pictures within 2 years. So far, I haven't given this place as much attention as the other place, but my plans are to do even more hinge cutting, which I feel will really help me. I passed a nice 140 over there this year during ML season that came out right at dark. He had to have been bedded right in one of my spots that I had thickened up.
I still have goals to reach at both places, but I guess that's a good thing, because it keeps me working and on my feet.
