Large Mammals and the Ecosystems They Shape

Large mammals are not just charismatic symbols of wilderness; they are ecosystem engineers. Elephants create water holes that other species depend on during droughts. Wolves reshape the behavior of prey animals, which in turn affects vegetation patterns. Beavers build dams that transform streams into wetlands, creating habitat for countless other creatures.

Many large mammal populations have declined dramatically over the past century due to hunting, habitat loss, and human-wildlife conflict. Yet there are also remarkable recovery stories. Wolves have returned to parts of Europe and North America. These successes show that with protection, space, and patience, large mammals can recover.
