Bridges have opened in woodland near Canterbury, doubling the area available to a herd of free-roaming European bison in Kent.

The two crossings, in West Blean and Thornden Woods, allow the animals to access an additional 50 hectares of habitat, increasing their roaming area to 100 hectares.

Kent Wildlife Trust said camera footage had captured the herd using the bridges for the first time as they began exploring areas of woodland that were previously inaccessible to them.
