PIPISTRELLE BAT
(PIPISTRELLUS PIPISTRELLUS / PYGMAEUS) ACTION PLAN
This plan has been prepared by the Wildlife Trust in
conjunction with the County Mammal Recorder, Phil. Richardson.

Sector The Northamptonshire
Bat Group
1 INTRODUCTION
The Pipstrelle is the most common bat in the
British Isles. It has recently been discovered that what was once considered to
be a single species is actually two separate species, making it more difficult
to assess the status and distribution of Pipistrelles. All species of bat found in Britain are legally protected and are
considered to be priority species in the national Biodiversity Action Plan.
2 CURRENT
STATUS
2.1 International
/ National Status
·
Although it remains the most abundant and
widespread bat species in the UK, the Pipistrelle is thought to have undergone
a significant decline in numbers this century.
Estimates from the National Bat Colony Survey suggest a population
decline of approximately 70% between 1978 and 1993. The problems of estimating
population trends have been compounded by the recent discovery that there are
two species – the Common Pipistrelle (Pipistrellus
pipistrellus) which echo-locates at 45kHz; and, the Soprano Pipistrelle (Pipistrellus pygmaeus), which
echo-locates at 55kHz. This action plan will cover both species
·
Pipistrelles are protected under Schedule 5 of
the Wildlife and Countryside Act 1981.
·
The Pipistrelle Bat is listed in Appendix 3 of
the Bern Convention, Annex IV of the EC Habitats Directive, and Appendix 2 of
the Bonn Convention (and is included under the Agreement on the Convention of
Bats in Europe).
·
It is protected under schedule 2 of the
Conservation (Natural Habitats, etc) Regulations 1994 (Regulation 38).
2.2 Local
Status
In Northamptonshire, records of the Pipistrelle
Bat and its roost sites are collected by the Northamptonshire Bat Group. The two Pipistrelle species are the two most
common bat species across the county.
3
CURRENT FACTORS CAUSING LOSS OR DECLINE
·
Disturbance and destruction of roosts, e.g.
loss of access to actual or potential sites through building alterations and
loss of maternity roosts through the use of toxic chemical timber treatments.
·
Loss of insect-rich feeding habitats, e.g.
woodlands, woodland edge, field margins and wet pasture.
·
Fragmentation of feeding habitats and flyways
such as wetlands, hedgerows and other suitable prey habitats.
·
Reduction in prey abundance, due to modern
farming practices and inappropriate riparian management.
4 CURRENT
ACTION
·
The JNCC recently commissioned the Bat
Conservation Trust to run the National Bat Habitat Survey, to provide
information on habitat preference and distribution.
·
The DETR commissioned a National Bat Monitoring
programme. This programme includes the Pipistrelle.
·
The National Bat Colony Survey has monitored
many Pipistrelle roosts since 1978, recording the size of annual summer roost.
·
Research is being carried out by a number of
organisations investigating reproductive physiology, mating strategies, field
activity, and the morphology and ecology of the two Pipistrelle species by
investigation of echo-location calls and mitochondrial DNA.
·
Scottish Natural Heritage has developed design
briefs for the conservation of Pipistrelle roosts in houses.
·
The Northamptonshire Bat Group continues to
collect and collate sightings of the Pipistrelle Bat
·
The Northamptonshire Bat Group gives a range of
talks on various aspects of bat ecology, conservation and education.
·
English Nature has a statutory duty to enforce
the legal protection of bats. They are statutory consultees for planning
applications which may affect bats.
