Those tree tops will provide cover and some of 'em might provide browse, depending on what species of tree they are. Usually during cold weather, deer like to lie down during the day in a fresh cut over since it allows them to get the sun for warmth and the debris helps block the wind. I'd set up in an area where the travel routes to and from the swamp are located, and any areas that lead into prime feeding and bedding areas on the perimeter of the cut down. The deer might have altered their patterns while the timber was being cut, but usually within a few days of all the activity stopping, they will resume normal travel and feeding patterns. I'll tell you this, next year with the new growth that will come into the cut down, you should experience better action than prior to the timber being cut.
