Lunchtime chats with Dr Tina Aughney - Bat Roost Restoration and the Green Bridge

Summary

We are delighted to chat to Tina about bat mitigation measures undertaken on the N18 road scheme. Garryland House, an existing derelict house located in Garryland Woodland, was renovated as a maternity roost for lesser horseshoe bats. The number of lesser horseshoe bats recorded in Garryland House has seen an annual increase since works were completed in April 2011. Tina will also touch on the construction a green bridge for safe passage of the bats, and other species across the motorway.

Description

The vicinity of the new road scheme of the N18 is important for bats in general and the lesser horseshoe bat in particular. The N18 scheme was merged with two other schemes to form the M17/M18 Gort to Tuam PPP Scheme. This road was built and opened in September 2017.

As part of the bat mitigation measures, Garryland House, an existing derelict house located in Garryland Woodland, was renovated as a maternity roost for lesser horseshoe bats. The number of lesser horseshoe bats recorded in Garryland House has seen an annual increase since works were completed in April 2011. The renovation works have significantly improved the building as a maternity roost and numbers present now match historical records from the 1970s having declined to zero in the 1990s. In addition, the building now provides suitable roosting sites for this species all year around, which was previously not the case.
As part of the bat mitigation measures to facilitate the safe movement of this bat species across the motorway, a green bridge was constructed. The location of the green bridge was determined by radio tracking of lesser horseshoes within the Coole Park and Kiltartan Cave area. Preliminary trail camera surveillance has documented various terrestrial mammal species crossing the motorway. Therefore, the green bridge also facilitates the safe passage of other wildlife species.

Mitigation and monitoring works is funded by Galway Co. Co. and works are completed under licence from NPWS.
