Wild Mink   
(13/Nov/2012).
So far as anyone knows there are no wild mink on Lea Marsh but this ferocious predator has been seen near by. The photo above shows a mink trap. It isn't actually designed to catch the little beast (should one turn up) but to reveal the presence of minks, if and when they arrive. Wild mink will devastate other species if they colonise Lea Marsh.
