A herd of bison is having a “great impact” on woodlands just a few years after being introduced in a UK-first to help manage habitat for wildlife, conservationists say.

The bison in Blean Woods, Kent, have also been inspiring people about more wildlife-rich habitat.

With new “bison bridges” opening up in the reserve, the animals will soon be roaming across 200 hectares (500 acres) of woodland, the team behind the scheme says.
