Rewilding asks less of a landscape in one sense and more in another: less active management and intervention from people, but a genuine willingness to let natural processes, grazing, predation, flooding, run their course again, even when the results are less tidy than a carefully managed reserve.
In practice this might mean reintroducing a missing species that once shaped the landscape, removing an artificial barrier that prevented a river from flooding naturally, or simply stepping back from land that had been intensively farmed and letting vegetation return on its own terms, however slowly that unfolds.
What distinguishes rewilding from ordinary conservation is this willingness to release control, trusting the ecosystem to reorganise itself once the right conditions and species are present again, rather than continuing to manage every detail indefinitely as though the landscape could never function without constant human oversight. It asks for patience above all else, since a landscape released from tight management rarely settles into its new balance quickly or predictably.
