Overall, such studies emphasize that understanding trophic cascades in large complicated ecosystems is challenging.3,4 Although loss of predators can cause ecosystem-level impacts2, reintroduction of carnivores, including wolves, doesnt always fully restore degraded ecosystems.23 In general, sweeping claims about trophic cascades caused by wolves are context-dependent and sometimes exaggerated. Conversely, simulated beaver cutting without elk browsing produced verdant, healthy stands of willow. But a coordinated campaign by the federal government exterminated almost all those predators, and bison, from the area.
