Keystone
were initially commissioned
by WSP Environmental
to undertake a visual
appraisal of all trees
identified in their
Phase I survey as having
the potential to support
roosting bats. We were
then retained by Atkins
to carry out the following:
Emergence surveys
of trees with the potential to support
bat roosts and which would be affected
by the proposed scheme
Visual inspections
of all bridges to identify potential
as bat roosts and flight corridors
Bat emergence
and activity surveys of all bridges
with the potential to support roosts
and/or function as flight corridors
Prepare a mitigation
strategy for bats and attend meetings
to discuss the strategy and associated
timing constraints/mitigation with
engineers
