Camp Pendleton is home to 147 bison species. The U.S. is working on a comprehensive management plan for bison on federal lands. It all started in the mid-1970s, when the San Diego Zoo gave a dozen bison, which it did not have space for, to Camp Pendleton. Space was not a problem at the 125,000-acre base. Last week, Interior Secretary Dirk Kempthorne announced plans for a bison working group to involve various federal agencies, including the Department of Defense, to develop an updated bison management plan for federal lands. One possibility might be to place bison herds on other bases with open spaces.
