Myotis brandtii was considered a vagrant for the purpose of Habitats Directive Article 17 reporting for the period 2007-2012, as a consequence of which no full Article 17 assessment was carried out for that period.

A specimen of Brandt’s Bat was first recorded in Ireland in 2003 when one was discovered clinging to a newly painted fence in County Wicklow. The bat subsequently died and its identification was determined by DNA analysis.
This sibling species to the Whiskered Bat is known from only five specimens found to date in Cos. Cavan, Clare, Kerry, Tipperary and Wicklow. However, these animals were identified by physical characteristics in the hand and not genetically. As no resident population has yet been identified on the island of Ireland, the species’ status remains unknown.

Comprehensive surveying of known populations of the Whiskered Bat (Myotis mysaticnus) were surveyed in 2008 / 2009 by the Centre for Irish Bat Research following the confirmation by D.N.A. analysis of the presence of at least one Brandt's Bat (Myostis brandtii) in Ireland. No further records for Brandt's Bat were revealed by this survey work.

Species Biology
Identification
Brandt’s Bat (Myotis brandtii ) and the Whiskered Bat (Myotis mystacinus) were only discovered to be separate species in 1971.
- The dorsal fur is long and bi-coloured being dark grey/brown at the base and light brown at the tip with a gold sheen.
- The ventral fur is greyish with a yellowish tinge.
- The skin is light brown and the base of the ear and tragus is lighter.
- The species is not as noisy as the Whiskered Bat when handled.
- It is rapid and agile in flight but it is not as manoeuverable as the Whiskered Bat.
- It cannot be separated from the Whiskered Bat by detector as their calls are identical.

Habitat
On the continent, the Brandt’s Bat is known to roost in buildings and bat boxes in summer. During the winter months, the species hibernates in caves, mines, tunnels and cellars. This is a woodland species but it is also found over water and feeds along tree lines and hedgerows and probably feeds on similar prey to that of the whiskered bat.

Habitats include but are not necessarily limited to;
- Semi-natural woodland (WN) [but possibly not Bog woodland (WN7)]
- Highly modified non-native woodland (WD)
- Scrub / transitional woodland (WS)
- Linear woodland / scrub (WL)
- Freshwater (F) [above rather than in.]
- Building and artificial surfaces (BL3)
- Non-marine caves (EU1)
- Artificial underground habitats (EU2)
Reproduction
Breeding is poorly understood at present. Females give birth to a single pup in June, depending on weather.

Threats faced
In the Article 17 Habitats Directive reporting for the period 2007-2012 no Threats were listed for this species.
Source: NPWS 2013.
The 2009 Irish Red List of Terrestrial Mammals notes that the species was only first confirmed as occuring in Ireland in 2003.
A survey reported in 2010 that surveys of maternity roosts of Myotis mystacinus, which Myotis brandtii closely resembles, did not identify M. brandtii again and it cannot currently be considered a resident species.

Conservation actions
In the Article 17 Habitats Directive reporting for the period 2007-2012 no Conservation Measures, in place or being implemented, were listed for this species.

The 2009 Irish Red List of Terrestrial Mammals lists threats identified for the species in Wales but notes that 'More information is required on distribution and roosting habits in Ireland to inform conservation efforts'.

In a 2007 All Ireland Species Action Plan for Bats a total of 37 Actions were identified for all Irish bat species
as part of the plan.

How can you help
The National Biodiversity Data Centre is trying to improve our knowledge
on the distribution of Brandt's Bat in Ireland. Should you
observe this bat species, please submit sightings to add to the
database. Detailed observations will assist us gaining a better insight
into where the species is most abundant in Ireland and we might also be
able to detect regional variations. Please submit any sightings and
photographs at
http://records.biodiversityireland.ie/index.php
All
records submitted on line can be viewed on Google Maps – once checked
and validated these will be added to the Mammals of Ireland Database and
made available for conservation and research.
