February 11th – Lesser Horseshoe Bat mitigation and monitoring

posted in: Uncategorized | 0

Our next talk is on Lesser horseshoe bat mitigation on a major road scheme: A case study on the A465 Heads of the Valleys Road (Section 2)

The talk will be delivered by Richard Green. Richard Green has been a professional ecologist since 1993. He worked as a Conservation Officer for the National Rivers Authority and Environment Agency and for a large multi-functional consultancy as Principal Environmental Scientist before setting up Richard Green Ecology Ltd in 2010.  Richard led a R & D project on bats and highways, resulting in the Design Manual for Roads and Bridges (DMRB) Interim Advice Note on bats (IAN 116/08) and was co-author of A Review of Bat Mitigation in Relation to Highway Severance(Highways Agency 2011).

Richard has worked on several road schemes where bats have been a significant receptor and is currently employed as bat specialist on the A465 HoV2 scheme. 

The A465 Heads of the Valleys Road Dualling (Section 2) Scheme passes through the Usk Bat Sites SAC. Construction started in January 2015 and is due to finish in 2020.Along the route there are lesser horseshoe bat flight lines, numerous caves and four lesser horseshoe bat maternity roosts, one of which is directly under the road in a viaduct.  Innovative mitigation and monitoring methods employed on this challenging scheme are presented, along with findings so far. Lesser horseshoe bat numbers in both maternity roosts and caves do not appear to have been affected by scheme construction, with overall numbers increasing in comparison to pre-construction numbers. Existing and new under-road crossings are being used by bats.
