Once the deer become accustomed to the new addition to the environment, I don't think you will notice any change in the deer activity. Over the summer, the owner of the farm that we lease began building a new home on a knoll over looking the alfalfa field we had been videoing. Well, the deer must have determined that there was no real danger associated with the activity up around the house because we nearly always would see 25+ deer in the field, even when they were hammering away on the house. I almost envy the owner. When they complete the house, he will be able to sit on the upstairs balcony and see the entire alfalfa field, the pastures on either side of it and the woods that slope down to the creek. That will be some great scenery!
