I like this one, and will add an observation kind of in the reverse direction. I am on s small, swampy, 30 acres with just 3 hidey hole food plots. I do not hold mature bucks at all in the spring or summer. I don't try to...I try to hold and attract lots of does and their offspring. I am on the land constantly throughout the spring and summer...working the land, logging, trail running, mountain biking, sugaring, walks with the dogs, etc. The does become completely accustomed to my movements on the land that they really pay little attention to me. On an ATV, a mountain bike, or even on foot, I can often pass by them within 20 yards or so and they just kind of let me pass with almost no alarm.
This time of year I begin seeing bucks show up looking for does and I really have little concern about my presence being given away by my resident does. The past few nights I've lowered my bow and climbed down out of my stand with a doe and her 2 fawns about 20 yards away. They just watched. I know it's kind of weird. But I don't hunt does. And if their quasi-tameness helps distract a buck long enough for me to make a clean kill I'm OK with it.
To answer the OP's question...the biggest improvement I have done has been the establishment of my small food plots in mature timber. They are the only game in town and really attract deer, not just for the food, but also for the social interactions. Lots of runs, scrapes, rubs...lots of edge habitat. I feather the edges considerably providing a ton of cover and early successional habitat.
