The bisons' grazing will clear spaces for other plants and animals to thrive in the woods at Blean.
European bison have been released into countryside near Canterbury, Kent, to help restore the area to its natural state.
The project, led by Kent Wildlife Trust and the Wildwood Trust, is taking place in West Blean and Thornden Woods. They will fell trees by rubbing against them, creating space and light and providing deadwood to help other plants and animals.The Trust said the next step is to introduce Exmoor ponies, Iron Age pigs and Longhorn cattle, whose natural behaviours compliment the bison.
Paul Whitfield, the director general of the Kent Wildlife Trust, said: "It's going to demonstrate the very real impact nature based solutions can have in solving the climate crisis."They will create an explosion of biodiversity and build habitat resilience, locking in carbon to help reduce global temperature rise."The European bison, which can weigh up to a tonne, vanished from the British Isles over 1,000 years ago, and were extinct in the wild at the end of World War II.
