It's estimated that approximately 5,700 tule elk are living in herds throughout California, including populations that roam the open spaces of the Diablo Mountain Range. Averaging 7 feet in length and weighing between 400 and 800 lbs, these large animals need space to roam as they seek food, water, and shelter to survive and rear their young. Over the years, many questions about the movement and health of tule elk populations have gone unanswered.
