We have deer walk into our camp during deer season on our property...just try to locate it as near to where you access the property as possible. The key to managing your herd on a property of that size is managing your hunting pressure as even a little pressure may affect it greatly. Locate the bedding areas and mark those as sanctuaries to where you do not disturb them when hunting or otherwise. In other words, do not walk/drive through or near them or allow your scent to blow into them when accessing them or while sitting on stand. Adding some patches of NWSG like you were saying should help if you locate them well. If you want to post an aerial of your property, I may be able to help you with some specific details of it.
