Rewilding

What is rewilding?

Rewilding is an approach to ecological restoration that seeks to rebuild functioning, self-sustaining ecosystems by restoring natural processes and reducing ongoing human control. Where classic conservation often works to hold a particular landscape in a fixed state — mowing a meadow, coppicing a wood, maintaining a target list of species — rewilding aims instead to restore the conditions under which nature can shape itself: natural grazing, predation, natural water movement, decay, and undirected plant succession.

The term entered scientific use through the conservation biologists Michael Soulé and Reed Noss in the 1990s, who linked large core areas, connectivity between them, and the presence of keystone species. In the following decades the idea spread through European practice — abandoned farmland returning to forest, rivers freed from canalisation, large herbivores reintroduced — and was popularised by writers such as George Monbiot.

Rewilding exists on a spectrum. At one end are large projects reintroducing missing animals across whole regions; at the other, small landholders simply stepping back and letting a corner of land go wild. What unites them is a shift in the human role from controller to enabler.

Rewilding and active restoration are not the same thing

Both aim at healthy ecosystems, but they take opposite paths — and confusing them creates false expectations.

Rewilding withdraws the human hand. It restores the conditions under which nature governs itself: natural grazing, predation, undirected succession, free-moving water. Success is measured by how little ongoing management is still needed. Whatever landscape emerges is whatever nature makes of it — self-willed and unpredictable.

Active ecological restoration — renaturalisation, Italian rinaturazione, German Renaturierung — actively restores degraded land to a living, functioning state — and keeps the human being involved as gardener and steward. Soil is rebuilt, water is retained, trees and companion species are planted, systems are designed. Success is measured by returning fertility, biodiversity and abundance. The human hand does not withdraw; it learns to work with natural processes instead of against them.

What Terra Humana does — and does not do

Terra Humana practises active ecological restoration, not rewilding. That is a deliberate choice about method, not a difference of degree.

In the scientific literature rewilding is itself counted among restoration approaches; both share the goal of functioning ecosystems. What separates them is the method — who does the work, and how much the human hand stays involved.

Our work at Sa Medada near Jerzu in Sardinia is active cultivation: Mediterranean food forests, syntropic agroforestry, permaculture design, soil regeneration, water retention, and an open academy for ecological learning. We plant, we tend, we observe, we intervene. A Mediterranean landscape shaped by four thousand years of human presence does not heal by being abandoned — it needs hands that know what they are doing.

We therefore do not describe our work as rewilding, and we make no claim to wilderness areas or species reintroductions. The concept is explained here because it belongs to the vocabulary of ecological restoration and because it names a real and valuable practice — pursued by others, with goals different from ours.
