Bat and bird scoping survey in Golborne, Cheshire

A bat scoping survey and bird scoping survey of a farm building in Golborne, Cheshire was carried out by UES.

Golborne is a small village south of Chester. The bat survey involved a detailed inspection of the building which will be affected by the planned development. When undertaking a bat scoping survey surveyors are looking for signs of use by bats. These signs can be tiny scratches on timbers, or even areas of smooth timber where bats have been rubbing against them. Bat droppings which are only a few millimetres are one of the field signs left behind. Experienced surveyors can distinguish between different types of bats by the droppings and feeding remains which are left behind.

If signs of use by bats are found in the barn then further bat surveys are carried out to record bats emerging from or returning to roost in the structure, at dusk and dawn. These bat emergence and return roost surveys can only be carried out in optimum conditions as recommended by the bat survey guidelines 2012. The guidelines state between May and August as the optimum period with temperatures above 10 Celcius.

The surveyors also noted any signs of use by breeding or nesting birds in the building. All nesting birds are protected under UK legislation.
