Anyone regardless of previous knowledge about bats can do it.
During single one-night training you can learn how to do it. We organise training sessions to explain the protocol. More information available in the Resources section.
Rivers, ponds and water reservoirs with slow waters.
Before starting a specific monitoring, you must sign up in this website from where you can easily set up your monitoring stations. If you prefer to re-activate an old transect contact us.
It consists of counting trawling bats (Myotis daubentonii/Myotis capacinii) and pipistrelle bats (Pipistrellus sp.) from four observing points.
Each transect consists in 4 sampling points, separated about 300m. At each sampling point:
1) We stand on the river bank with the flashlight crossing the river, at the water level.
2) For 10 minutes we count all trawling bats (Myotis daubentonii/Myotis capacinii) that cross the light.
3) We move the flashlight 45º up.
4) For 5 minutes we count all pipistrelle bats (Pipistrellus sp.).
We repeat the same protocol in all 4 points.
To learn how to distinguish the bats, check the Resources section.
One evening a year between June, July and August, without rain and strong winds. The survey always starts one hour after the sunset.
A powerful flashlight and a field notebook.
In this platform you have access to the tools to design and register your own transect. Create your own transect HERE.
Once the survey is finished, you will be able to upload your observations to the website and check the results from other stations.
Periodically we organise training sessions to provide the necessary knowledge to carry out this protocol.
