Introduction
In January 2021 we were commissioned to undertake a bat survey, a Preliminary Roost Assessment, of buildings at Lower House Farm in Wiltshire to support a planning application.

The purpose of the survey was to determine the potential for protected species, in this case bats, to be using the site.
The survey comprised an initial bat survey, called a Preliminary Roost Assessment (PRA), was completed for the twelve buildings on Site. This assessed each building separately to confirm any evidence of bats and potential for bats to be using any part of the structure.
Results
Bats – The PRA assessment of the twelve buildings on site were:
- Nine buildings recorded as having NEGLIGIBLE bat roost potential,
- Two buildings recorded as having LOW bat roost potential, &
- One building recorded as having MODERATE bat roost potential.
The nine buildings recorded as having NEGLIGIBLE bat roost potential required no further bat survey work.
The other three buildings required bat activity surveys to confirm whether bats were actively using them and if so, how bats were using them, these details would inform the proposed design for the project.
The two buildings recorded as having LOW bat roost potential were recommended to have a single bat activity survey each and the building recorded as having MODERATE bat roost potential was recommended to have two bat activity surveys.
