Post-Workshop Expedition  Proceedings



The European Alpine Bat Detector Workshop was first organized in Trenta (Slovenia) during 2012, followed by the second in Vercors (France) in 2015. Thus, this years workshop is the beginning of a new tradition, with the third of its kind.
      Nordic Chiroptera Information Center (NIFF)  organized the 3rd European Alpine Bat Detector Workshop, which was held in Askim (South-Eastern Norway), only 55 km from downtown Oslo and 37 km from the Swedish border.
      The aim of the workshop was to get field training in practical bat work, especially the use of various models of both passive and active bat detectors. Organizers were Leif Gjerde and Arnold Andreasson.

Successful workshop finished
We thank everyone who participated in Askim, and the people who participated in the bat call reference library collection trip afterwards.
      The results from the workshop will eventually be available electronically (pictures, presentations and bat call recordings), while the Proceedings will include the articles describing the talks, activities and results from the workshop.
      I am sure everyone will enjoy their knowledge and experience from the workshop, and the stay became a platform for future work and cooperation.
      Hope you will join us at the 4th European Alpine Bat Detector Workshop in September 2021.

Objectives

The objective of the workshop is to improve training and knowledge of the latest technology and experience on field identification of flying bats. The mixture of novice and well experienced bat workers (and everything between) enhances the learning process by self awareness and development.
      The target group is idealistic bat workers (enthusiasts/idealists, NGO's and scientists) who is or will work with bats in the future. Students and NGO's may apply for reduced fee. Commercial bat workers will be excepted if there is space.

  • Learn the basic theory of bat identification with the aid of ultrasound devices.
  • Field training in using active detectors, such as the Petersson (D240X, D980), the AnaBat Walkabout, the EchoMeter and misc. flat screen versions.
  • Learning how to operate the passive detectors produced by Pettersson (D500x), Titley (AnaBat Express and AnaBat Swift), Mini Batcorder (EcoObs) and Wildlife Acoustics (SongMeter 2, 3 and 4).
  • Analyzing bat calls by using software from Pettersson (BatSound), Titley (AnaLook), Biotope (SonoChiro 4) and Wildlife Acoustics (Kaleidoscope).

The results from our surveys will be published in the proceedings for the workshop, alternatively in a European periodical.

Equipment in which we will have available for testing are:

Passive detectors

  • AnaBat Express (Titley Scientific)
  • AnaBat Swift (Titley Scientific)
  • D500x (Pettersson Elektronik)
  • SongMeter 2 (Wildlife Acoustics)
  • SongMeter 3 (Wildlife Acoustics)

Active detectors

  • Pettersson (D100, D980)
  • Titley Scientific (Walkabout)
  • Wildlife Acoustics (EchoMeter)

Software

Temporary program

Start: The workshop building will be accessible from 1500 h on the 2nd of August, and the program starts at 1800 h.

End: The workshop will end on the 6th of August at 1000 h.

We will have at our disposal active and passive ultrasound detectors from three different producers (Titley Scientific, Petterson Electronic and Wildlife Acoustics). This will give the participants possibility to get familiar with different type of work equipment and possibilities that they offer.
      During the day we will analyze the recordings from previous evenings and attendants will be invited to have 20 minute lectures.
      In the evening we will divide in groups who will check different locations for bats. Each group will have at least one experienced bat worker, who will lead them and be responsible for the quality of the collected data.

Travel instructions

The 3rd EABDW will take place in Askim (in Østfold), a small village located 55 km from downtown Oslo.

The workshop will take place in the village of Askim at 59.585985 N 11.146326 W. It is a 10 minute walk from the train station in Askim to the the scout house.

Some distances and travel times:

Stretch km Time (h.minutes)
Gardermoen (Jessheim) - Askim 99 1.37
Torp (Sandefjord) - Askim 172 2.14
Göteborg - Askim 241 2.49

Airports
The nearest airports from Askim are:
1. Gardermoen - OSL (Oslo) - 99 km (1h 37min)
2. Torp - TRF (Sandefjord) - 172 km (2h 14min)
3. Landvetter GOT (Sweden) - 241 km (2h 49min)

Airplane companies leaving from Torp (Sandefjord Airport) are a.o. Norwegian Air Shuttle, Ryan Air (Irish), KLM (Dutch), Wizz Air (Hungarian).

The travel costs from Stansted (London) at 0940 h to Gardermoen on 2nd of August, and return (arrival Stansted at 1630 h) are 98 pounds (checked 6th Jan.).

Train from Gardermoen airport
NSB is the main company. From Gardermoen airport there is also "Flytoget" or the airport plane. They are both state owned, but the airport plane is a lot more expensive. Tickets for these are bought at separate machines and at separate ticket counters, but just few meters apart. So this can be confusing.

NB! The airports name is Gardermoen, but officially it is "Oslo Lufthavn". So searching databases you might need to use the official name. On train platform Gardermoen might be used.

Train from Gardermoen airport to Oslo S (Oslo Sentralbanestasjon). At Oslo S you need to change train for Askim.

All train, bus, tram, boat routes are available on: www.trafikanten.no or https://ruter.no/en/

Bat Call Reference Library Collection Trip
6th - 9th August 2018

During the 10th European Bat detector Workshop in Biddarai (the Basque Country) in 2017, there was established a working group whose aim was to standardize methods for collecting bat calls in the field. Special focus was on (1) developing microphone standards, (2) establishing a bat call reference library and (3) enabling inexpensive high quality detectors and microphones.

In connection to this work, the group will have a post-workshop expedition to Trøndelag (Central Norway). Three colonies will be visited on three separate days to collect calls from bats emerging the colonies, and from the surrounding habitats.

The species are from known colonies of Myotis brandtii, Myotis mystacinus and Eptesicus nilssonii, making species identification safe for the calls collected. Furthermore, no nearby colonies exist of any confusing species.

The results from the trip will be included in the Proceedings.

   

 


Proceedings

There will be a DVD publication after the workshop which include pictures, sound files, analysis and statistics.

In addition we hope to publishing the results of our bat detector workshop in a special issue of Gudnjoloddi (ISSN 0809-2362). It will be published by NIFF and Bluebat together. The title will be "Proceedings from the 3rd European Bat Detector Workshop, held in Askim (Oslo) during 2nd to 6th of August 2018". Leif Gjerde will be editors of the proceedings. It is expected that each lecture will be published as a separate article in the proceedings. If no manuscript is received, we will publish the abstract alone.
      There is no limitation for the length of the articles, but the contents should be relevant to the talk. The proceedings will be in English entirely. There will not be included abstracts in Norwegian.

Deadline for contributing article manuscript is 31 December 2018.
