'Invisible' fence installed at Walton Common to stop cattle wandering

A small herd of Dexter cows has been let loose on a Somerset nature reserve for the first time in decades.

Walton Common, near Clevedon, has not been grazed for at least 60 years because of a lack of fencing.

Now, in a bid to improve the grassland, an electric cable has been installed underground so cows fitted with shock collars can be introduced to the common.
