Landowners urged to help try and stop mink in their tracks
Despite efforts by a team at Tophill Low nature reserve near Driffield to control the creature, which has been breeding in the wild since the late 1950s, their numbers are at their highest in more than a decade.
Large numbers of water vole appear to have attracted mink, which also eat rabbits, ducks, chickens, fish and frogs, from far and wide.

Warden Richard Hampshire said mink had already seen off water vole across large swathes of the UK, and it would be a “real shame” if the River Hull corridor, traditionally a stronghold for native species, lost its water voles.
He said: “If we walked away and left them to it, they would become extinct in the next few years.”
A lot of the river Hull is no longer managed because of Government cuts, and rafts installed some years ago had “fallen to bits”, adding to the problem.

Usually a couple of mink are spotted on the site every year, but in September they found four and the latest footage from cameras installed as part of a study on otters has picked up several more, putting the total for the year at around 10.
