Wolf Park is a nonprofit education and research facility which was established in 1972 by Dr. Erich Klinghammer. Along with research and seminars on wolf behavior, particularly reproductive and inter-pack social behavior, Wolf Park provides interpretive programs to school groups throughout the year by prearrangement. They are also open to the general public from May through November and Saturday evening for Howl Nights. The park is home to several packs of gray wolves, plus coyotes, foxes, and bison. They are incorporated under Wolf Park, Inc. which is located in the small town of Battle Ground, Indiana, United States.
