Peatlands store more carbon than all other terrestrial vegetation combined and provide unique habitat for specialist wildlife, but drainage for agriculture has degraded millions of hectares with severe welfare consequences.
Peatland rewilding addresses welfare harms caused by habitat degradation. Curlew populations that have declined by 48% since 1994 in the UK face food scarcity and nesting failure on drained peatland that can no longer support the invertebrate communities they need. Restoring water levels by blocking drainage channels rapidly improves invertebrate abundance, benefiting the food web above. Adders, which have lost much lowland heath and peat habitat, benefit from the structural complexity of restored peatland. Peatland rewilding combines animal welfare, carbon sequestration, and flood mitigation in one of the highest-value landscape interventions available in temperate regions.
