Passage A Rewilding projects restore large predators or herbivores in the hope that their effects will cascade through an ecosystem. When browsing pressure falls or prey behavior changes, vegetation and habitat can recover without continuous human management. These cases show the value of rebuilding ecological interactions, not merely preserving species counts. Passage B A cascade observed in one park may depend on present climate, fences, livestock, and species introduced long after the supposed historical baseline. Rewilding should not be judged by resemblance to a single past date. Its goals must be explicit about which processes, communities, and human uses are being prioritized.
