In connection to the European Bat Research Symposium every three years, it has since 1991 been a tradition to organize a bat detector workshop just before or after the conference.

The next workshop will be organized  in 2024 in connection to the 16th European Bat Research Symposium (located at Tarragona, Catalonia). The workshop will be located in the village Mura which is in the edge of Sant Llorenš del Munt i l'Obac Natural Park. The village and park is located just north of Barcelona.

The aim of the workshop is to get field training in practical bat work. This includes the use of various detectors, both active and passive. But also improve our skills on bat call analyzing software.

The workshop is being organized by Leif Gjerde from the Nordic Chiroptera Information Center - NIFF (e-mail: niff@flaggermus.no; mobile phone: + 47 40228817), in cooperation with the staff from the Natural Science Museum of Granollers.

If you decide on finding your own accommodations, the cost at the Els Caus Hostel is:
 ● breakfast - 6 euro
 ● lunch - 15 euro
 ● dinner - 15 euro

We will have our lectures and workshop during the day at the Els Caus hostel. In this way we save travel between events and meals.

Workshop costs:

Registration: 200 euro
4 nights with food: 184 euro


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, D1000), the AnaBat Walkabout and misc. flat screen versions.
  • Learning how to operate the passive detectors produced by Pettersson (D500x), Titley (AnaBat models) and Wildlife Acoustics.
  • Analyzing bat calls by using software from Pettersson (BatSound), Titley (Anabat Insight and AnaLook) and Wildlife Acoustics (Kaleidoscope).

The results from our surveys will be published in the proceedings for the workshop.

Sant Llorenš del Munt i l'Obac Natural Park

The Natural Park of Sant Llorenš del Munt i l'Obac is made up of the massif of Sant Llorenš del Munt and the Obac range. It has a protected area of ​​13,694 hectares distributed between the counties of Bages, VallŔs Occidental, and MoianŔs. The topography of this entire area is very rugged, full of cliffs and channels, with torrents and streams in all directions. Geologically, conglomerates predominate, forming a relief similar to the neighbouring massif of Montserrat.


The park encompasses two massifs: that of Sant Llorenš del Munt, culminating in the mentioned peaks of La Mola and Montcau, each over a thousand meters, and the Serra de l'Obac, not as elevated; its highest peaks are Castellsapera (939.3 m above sea level), the hill of Castellar (931 m above sea level), and the hill of Tres Creus (929.7 m above sea level). Both mountain ranges are separated to the south by the Riera de les Arenes (a tributary of the Riera de RubÝ) and to the north by the Estenalles stream. The central point of the park is the Estenalles pass (870.4 m), where there is an information centre.

Flora and fauna

Predominantly Aleppo pine forests give way to Scots pine and Austrian pine at higher elevations. Holm oak forests dominate, enriched above 800 meters with species like rowan and boxwood. Cliff areas host unique plants such as living fossils like Ramonda myconi and endemic Saxifraga callosa. Spring brings a vibrant display of wildflowers, including thyme, lilies, tulips, and narcissus.

The park boasts extensive forests, stunning cliffs, and towering crags, providing optimal conditions for refuge, breeding, hibernation, and migration for numerous vertebrate species. The diverse ecological environments within the park support distinct faunal communities, ranging from typical rock-dwelling inhabitants to animals found near farmsteads and woodland fauna. With nearly two hundred vertebrate species, including carnivorous mammals like the stone marten, genet, fox, and badger, the park plays a crucial ecological role. Wild boars have notably increased, leaving traces despite hunting pressure. Squirrels, rabbits, and diverse bird species, such as blackbirds, pigeons, and jays, are commonly observed. Raptors like the short-toed snake eagle, hawks, and falcons occasionally grace the sky, while rare sightings may include vultures and possibly the golden eagle. Noteworthy are wintering colonies of the Schreibers' long-fingered bat. Reptiles like the Montpellier snake and Lataste's viper inhabit rocky ridges, and amphibians, including colourful salamander larvae and various toad species, thrive in mountain springs.


It has a subhumid Mediterranean climate. Therefore, the main forest that develops here is the evergreen oak forest, and there are also pine forests, although there are significant cork oak forests, such as those of Les Teixoneres or Sot de la Bˇta.

More information of the park is available here.

The parc administration web-page is unfortunately only in Spanish or Catalonian.



The Bat Fauna of Catalonia

The species list to the right is taken from The Atlas of European Mammals (de Beaufort et al. 1999). Since, additional species have been described from Catalonia, the list is not complete.

At least 27 bat species have been found in Catalonia (see list on right side). The region is diverse in habitats, and includes everything from Mediterranean Climate to Alpine mountains. In the list we have marked in green the species we most likely will encounter during the workshop. Marked in blue are species we might encounter if we are lucky.

Bat Research in Catalonia
The BiBio Research Group (www.bibio.org) has a long tradition of coordinating successful biodiversity monitoring programmes. They coordinate four monitoring programmes in Catalonia, based on citizen science. The programme covers a wide range of taxa, including bats (www.batmonitoring.org), as the core part of their research lines. More particularly, they investigate population trends of common and endangered species and how they are affected by global change.
      The target species which are being monitored for population trends are Pipistrellus pipistrellus, Hypsugo savii, Barbastella barbastellus, Rhinolophus ferrum-equinum, R. euriale and R. hipposideros.
      We hope that the workshop will
be of mutual benefit for BiBios' Bioacoustics Monitoring Group and our workshop participants.

Travel instructions

The workshop is held in the Sant Llorenš del Munt i l'Obac Natural Park, which is located in the region of Barcelona, just north of the city of Barcelona. It is less then an hours drive from the city.

Barcelona is an international city with travel connection internationally by bus, train and aeroplane. Below are some suggestions for more information and booking. Prices may vary a lot, and you should check different booking companies. It may be practical to have an extra day in each end of your travel, to avoid any surprices during your trip.

Barcelona Airport (BCN)
Checking flight prices and making bookings is probably easiest using Skyscanner.  A one-way trip from London to Barcelona costed on 9th of May under 100 euros.

Barcelona train station
More information and booking is possible on Trainline. On www.thetrainline.com a trip from Frankfurt to Barcelona costs from 130-200 euro each way, and takes 12-20 hours.

Bus lines
More information and booking is possible on Flixline. On Felxline a trip from Frankfurt to Barcelona costs from 500-800 euros. The disadvantage by using buslines, are the long trips. From Frankfurt it takes at least 21 hours.

We are checking possibilities for local transport from Barcelona to Mura. This will be agreed upon directly with the participants. At the worst, it is possible to get a ride with one of the participants who travel by car.

There will be a DVD publication after the workshop which include pictures, soundfiles, 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. The title will be "Proceedings from the 11th European Bat Detector Workshop, held in Barcelona (Catalonia) during 6th to 10th of September 2024". 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 German, French, Catalonian or Norwegian.

Deadline for sending abstracts is 15. July 2024.
Deadline for contributing article manuscript is 10. August 2024 (or as agreed upon).
