On 29th and 30th October Ann Hanson and colleagues from the Yorkshire Mammal Group joined East Keswick Wildlife Trust to survey Fitts Fields for small mammals. 50 humane large Longworth traps were set on the Saturday evening and on Sunday morning we met to open the traps.

32 of the 50 traps had small mammals in them, all looked healthy and were a good weight.

We recorded: 14 bank voles, 3 field voles, 14 wood mice and 1 common shrew.

This shows that there is a very good population of small mammals in these fields and although we did not find a harvest mouse this time, we do know that they are living here.
