Lesser horseshoe bats in Ireland
There are many factors that set the lesser horseshoe bat apart from the other eight Irish bat species and so merit the production of an action plan focused on it alone. It has limited access to suitable summer and winter roosts due to its inability to land and crawl through small openings, needing to fly directly into a structure. Although it does not have a specialised diet, it prefers to feed in broadleaf woodland, a scarce habitat comprising less than 2% of Ireland’s tree cover. Its distinctive echolocation call enables it to fly within cluttered environments but does not travel far, so the bats need to fly close to linear features to navigate through the landscape. It is the most photophobic of all the Irish bats.
This Species Action Plan (SAP), the first SAP for the lesser horseshoe bat in Ireland, aims to guide, inform and provide structure for the conservation management of this important species between 2022-2026.

What are the issues?
The most recent estimate of the lesser horseshoe bat’s population is 14,000 individuals, though population monitoring indicates that the species is confined to six western counties, occurring in clusters, with large areas that contain few or no colonies. Two recent population genetic studies indicate that this species now consists of four distinct sub-populations that have developed due to habitat fragmentation caused by agricultural intensification and urbanisation. The lesser horseshoe bat is listed on Annex 2 of the EU’s Habitats Directive and there are 41 Special Areas of Conservation for which this species is a Qualifying Interest.
The actions described in the SAP are those considered necessary to restore this species to a favourable conservation status.

Working in partnership
Working with local authorities
The first Species Action Plan for the lesser horseshoe bat in Ireland has been published by the Irish Government and is the product of extensive collaboration between the National Parks and Wildlife Service and Vincent Wildlife Trust. The aim of the plan is to guide, inform and provide structure for the conservation management of this important species over the next five years (2022-2026)
