joel had some good tips. 40 acres is small though. i think it would really depend on how your deer are on the property all ready. what do they use that 40 acres for? bedding areas, food, just passing through? if you got a lot of deer moving through your woods already i dont know if i would do alot to it right off the bat. just sneak in and hunt it. thinning does is always a good tip. like joel said deer need a santuary where no human scent every get in there and they have a good place to hide. i would spend my time at first just observing the deer and there patterns and then decide where a food plot or some other man made item will help you hunt them more sucessful. i guess what im trying to say is just be patient and whatever you decide to do just dont over do it.
