For an excellent educational webinar on improving wildlife habitat in and around woodlands, follow the link below to a presentation by Dr. Craig Harper. Although Dr. Harper is from the University of Tennessee, his presentation is applicable to hardwood forests in the eastern half of the U.S. It is over an hour long, but I highly recommend it for gaining a solid understanding of what “wildlife habitat” truly means (food, water, cover, and space) and how to manage various areas of a woodland and adjacent fields to create high quality habitat. After understanding the basic concepts, you can search online and find numerous presentations from Dr. Harper on more specific topics such as improving deer habitat if that is your priority.
