Bats as indicators?
Represent a fifth of all mammalian biodiversity
Occupy a wide range of niches
Provide a number of ecosystem services
Sensitive to climate change as depend on nocturnal flyinginsects (themselves sensitive to changes in temperature)
Sensitive to pollution through poisoning of their insect preybase

Why are bat indicators important?
Policy Implications and Profile Raising
Why just birds and butterflies?Raise profile on international biodiversity agenda
Fund raising mechanism for long-term monitoring
Importance in Landscape Planning
Landscape-wide indicators of ecosystem function

A monitoring program needs
Long-term records generated with a common protocol
Sustained funding for personnel and resources.
Successful models train volunteers in monitoringprotocols, who then donate their time during the annualsurveys.
However, there is no global monitoring program forbats and no agreed upon protocols for evendeveloping one

Indicator Bats Program - iBats
To generate monitoring data on bat species distributionsand abundances across the world to evaluate the effect of
global change on biodiversity loss.Collaborate with existing national and international bat
monitoring projects
Initiate new bat monitoring projects
Develop and implement novel monitoring protocols
Provide a centralised common database to store and analyseglobal bat monitoring data
Disseminate protocols and results through an interactive web dataportal (www.ibats.org.uk)

Monitoring Irish bats acoustic car transects
The first pilot in 2003 with the newly formed Bat ConservationIreland - 7 survey teams
2004 - 17 survey routes
2005 - 21 routes with 40 volunteers
2006 - 26 routes with 59 volunteers
Adopted by the Irish Government as the official monitoringtechnique for 3 species
BCIreland has been expanding to more intensive monitoringtechniques.

UK Results 2005-2006
A total of 6911km (3573km 2005; 3338km 2006) of roadwere driven.
A total of 10147 (4719 bats 2005; 5428 bats 2006) wererecorded from 10 bat species/species groups and a total of910 (399 2005; 511 2006) other mammal species were
recorded from 28 species groups. Bats encountered included common, soprano and
Nathusius pipistrelles, Leislers bats, noctules, serotines
and Myotis spp. The top seven other mammal species encountered were:
rabbits; bats; foxes; hedgehogs; mice; hares; and badgers.

Differences in community composition
Soprano batsencountered morefrequently inScotland and westof Ireland thanEngland or Wales.
Is this linked toclimate sopranosforage on waterborne insects?
Is it the sameacross Europe?
