This post is a little old, but I just had my timber logged the summer of 2009 so thought I would offer my experience with this. I didn't do a thing to it for the 2009 season and didn't have as much luck as would have liked to. So this spring I took our 6' bush hog on the three point hitch of a tractor without a loader (the loader makes the tractor longer and harder to make tight corners in the timber). I mowed just a couple paths almost all the way through the timber and then a couple across it. During the summer when the briars were thick, the deer used them like a highway. I planted beans right on the paths and the deer loved it. They were still surrounded by good cover and could dart off the path if they felt threatened, but used the paths I mowed a lot since it was such easy walking for them. They are lazy just like us... [;)]
The first pictures is the loggin trail the loggers left before I mowed it, the second is after I mowed it in the same exact spot and if you look close you can see the beans. The deer used the logging trail already before I mowed it, but after I mowed it, the activity really picked up. The deer (and other animals) completely wiped out the beans before they could put a pod on. I think they must have loved being abled to stand right in the middle of the timber and feel safe and be able to eat one of their favorites.
Anyways, if you have a bushhog mower or something similar available to you I think it is a great idea. I will keep these paths mowed once a year from here on out.
