Project with bat boxes was launched as a result
of need to provide roosts for some forest-dwelling or fissure-dwelling species they
require holes or fissures in trees for roosting, mating and breeding. Due to
the lack of mature forests with old trees and increasing presence of altered
habitats, the availability of natural roost has dramatically decreased. Bat
boxes are a compensatory measure, and therefore should not be used as
definitive replacement for natural roosts.
Nevertheless, it is important to know the number of individuals and which species might occupy them. The monitoring is mainly focused on urban species such as common pipistrelle (Pipistrellus pipistrellus), soprano pipistrelle (Pipistrellus pygmaeus), Kuhl’s pipistrelle (Pipistrellus kuhlii), Nathusius’ pipistrelle (Pipistrellusnathusii) and forest-dwelling species such as Leisler’s bat (Nyctalus leisleri), giant noctule (Nyctalus lasiopterus), brown and grey long-eared bats (Plecotus auritus and Plecotus aurstriacus), greater mouse-eared bat (Myotis myotis), Iberian Natterer’s bat (Myotis escalerai), Bechstein’s bat (Myotis bechsteinii) and western barbastelle (Barbastella barbastellus).
Who can participate?
Monitoring of the bat boxes is aimed to wide public, from more specialized to more familiar. Depending on the degree of knowledge about bats, this monitoring can be done in two ways. However, if you have any questions, you can contact us at firstname.lastname@example.org .
Where it can be carried out?
This monitoring can be carried out in any habitat and location; you just need to install a bat box and monitor it (or you can track some bat box from our network that is available). Before starting you should ensure that the box you want to follow is not being monitored by another person. Because of that, you will need to sign up and check the availability of every bat box.
What does it consist of?
Photographing and counting bats
When it should be carried out?
It is very easy. This monitoring is carried out throughout whole year. Bat boxes are being checked once per season of the year (winter, spring, summer and autumn).
How is it carried out?
Based on your experience, it can be carried out in two ways:
It is very important to remember that in any case animals must not be handled/manipulated!
The count can be barried out using a flashlight that allows illuminating the interior of bat box and taking photo.
Which equipment is needed/necessary?
Photo camera in case of counting animals from the photo
Sending and checking the results
application you can access to the tools register your bat boxes, you can send
us comments and see the results from another bat boxes within our monitoring
network/system. The results must be submitted before the end of August. The
data can be submitted online directly from the field, or it can be written down
to field notebook and uploaded afterwards.
Occasionally we organize
training sessions in order to disseminate information about the monitoring, to
encourage the volunteers and to provide them with the necessary knowledge to be
able to carry out this simple protocol, for which previous knowledge about bats
is not essential. An alternative to training sessions is to accompany other
researchers during their fieldwork, and to obtain enough experience within one
day to be able to carry out the procotol autonomously.
