Knepp Wildland has become one of the most important areas in Britain for breeding birds. It's brimming with butterflies and humming with crickets. It's bucking the trend of biodiversity declines across the board. Why? Because the team here has allowed in the untidy. They've welcomed a tangle of scrub and a knot of thorns. The most inspiring thing about this is the speed of change. Just 15 years ago, this was an intensive farm. Knepp Wildland is a member of the European Rewilding Network, a collection of groundbreaking initiatives across the continent, brought together by Rewilding Europe as part of a broader rewilding movement.
