Case studies
A Brickworks with Hibernating Bats
Creation of a hibernation roost for brown long-eared bats to compensate for the loss of a former brick kiln roost that had been created as part of an EPSM licensed project. Unfortunately the kiln roost had become unsafe and a modification to the licence and mitigation strategy was needed.
ANHIB Maternity Colony Bat Fence Mitigation
A three species maternity colony identified within a disturbance distance of bridge replacement works (2019). Impacts assessed as vehicle collision mortality, severance of commuting routes and disturbance (noise vibration, light) of during maternity season potentially leading to roost abandonment. Main mitigation included bat fencing and timing of works.
Ashton Court, Bristol (original case study requiring update)
The gate house was part of a refurbishment scheme to create residential living space. Due to the presence of several bat species, the living accommodation was carefully isolated from the existing roosting spaces.
Avoidance of swarming site loss during restoration works at Cliveden.
Autumn swarming bat behaviour was confirmed in 2009 at the east and west ferneries (internally and externally) of the South Terrace at Cliveden. This National Trust site underwent major restorative works between 2012-2017, planned to avoid affecting bat use of the site. Post-development monitoring confirms continued bat swarming activity onsite.
Barn Conversion in Elmore, Gloucestershire
The owners/residents of a tythe barn proposed to convert its west/mid-sections into additional residential. Day roosts for Natterer’s, brown long-eared and common pipistrelle were present. Mitigation included integrating a bat loft into the existing barn space under EPS licence. Post-development monitoring confirmed continued bat presence afterwards.
Barn Conversion, Macclesfield (original case study requiring update)
Refurbishment project for disused barn hosting roosts for several species, including Natterer's bat, common pipistrelle, soprano pipistrelle and brown long-eared bat.
