REWILDING: IS IT ALL JUST A CELEBRITY CULT?

In July, four bison were released in Kent. But is rewilding the best way to boost biodiversity?

-  PROF ADAM HART

Rewilding is all the rage. Landowners are exhorted to rewild farmland, moorland and mountains, while governments are asked to commit to rewilding policies. During No-Mow May (a wonderful initiative) people talked of roadside verges being rewilded. And there's a thriving ecosystem of books, blogs and websites urging homeowners to rewild their gardens, which seems uncannily similar to 'gardening for wildlife'.

In fact, much of what is called rewilding is a rebrand of something we already had. When the Aspinall Foundation announced a plan to move elephants from a zoo in Kent to Kenya, the venture wasn't called 'translocation' or 'captive-release' or 'reintroduction'. No, these elephants were to be 'rewilded'.

Rewilding makes intuitive sense if we take a big picture view of it. The basic idea is that humans have converted land that was once wilderness into some other form of land-use. Rewilding aims to restore land to the way it would be if we weren't around. This wild state, it is presumed, supported a more diverse and functionally complex ecosystem.
