Bat surveys of buildings and trees in relation to proposed works, including mitigation for the new discovery centre, a new restaurant and tree surveys in support of a play area.

The new discovery centre was built in an old courtyard used by bats and mitigation required changing the main access point used by a colony of long-eared bats and changes to parts of the bat roost. A novel purpose built innovative heating system for long-eared bats was installed along the ridge of an attic to enhance roosting opportunities.
                        







Re-development of a site with eight blocks of derelict flats


Surveys revealed one of the largest
noctule bat roosts in the country, along with smaller numbers of other more common species. Great crested newts were located in ponds within 500m of the site and a number of bird species recorded breeding  in buildings and vegetation around the site.


A mitigation scheme for the bat roosts was devised and agreed with the Local Planning Authority and Natural England to enable the bat roost to be retained in a refurbished block of flats with vegetation screening and the other flats replaced with new housing.


Bird boxes were recommended to replace lost swift and other bird nests. However, it was agreed that  no action was necessary in relation to the nearby population of great crested newts. 



Bat surveys in support of a Management Plan for Breadsall Railway Cutting SSSI.

Bat transact survveys undertaken to identify key species and foraging areas; potential bat roost identified and recommendations for enhancement made.




Large extension to a bungalow in
woodland in Nottinghamshire.
 




A small roost of long eared bats found within the attic and a license obtained to remove the existing access point and reduce the size of the roost. Enhancements were made to the remaining roost including new access points and roosting opportunities. Monitoring  revealed the roost not only reminded in use but was used by twice as many bats as before.

Renovations and extensions to a listed building

Bat licence obtained for major renovations to a derelict listed outbuilding at a nursing home. New and modified roosts for small numbers of long-eared and pipistrelle bats using the building were made available in attic voids, with temporary roosts made available in other buildings and bat boxes in trees during the development.







 
Small Loft Conversion






Surveys of a proposed loft extension revealed bats roosting throughout the large spacious attic. A license was obtained to reduce the area available to the bats to allow a conversion of most of the loft area to a new master bedroom, on-suite and dressing room. The area left for the bats was still large enough to accommodate the roost and allow the bats to fly within the roost space. Additional features were added to provide more roosting opportunities.
