Wildlife charity monitoring Yorkshire's water volespublished at 18:00 British Summer Time 8 April 2019
A wildlife charity is trying to find out how many water voles there are in Yorkshire amid fears it is in decline.
Yorkshire Wildlife Trust have recruited a trainee who will be out and about looking for signs of the semi-aquatic rodent.
It wants to find data to support anecdotal evidence, which suggests numbers of the once common mammal have gone down.
