In the beginning of 2020, Aage V. Jensen Nature Foundation acquired a big nature area Søholt Storskov placed between the three largest lakes in the middle of the island of Lolland in the Southern Baltic Sea. The area of 1,134 ha comprises old and young deciduous forests, lakes and agricultural land. Map of the area: https://www.avjf.dk/wp-content/uploads/2020/04/Søholt-Storskov_Sort-afgrænsning.pdf Description in Danish: https://www.avjf.dk/avjnf/naturomraader/soeholt-storskov/ The foundations goal is to preserve and improve the nature values and biodiversity in the area. Prior to the planned nature restoration activities, Aage V. Jensen Nature Foundation initiated a baseline monitoring programme for the biodiversity in Søholt Storskov. Bat survey conducted by Thomas W. Johansen and Hans Baagøe was a part of this programme.Sampling Description
Study Extent
N/ASampling
The whole area of Søholt Storskov was devided in four survey areas. Bat activity was recorded using automatic bat detectors placed at 20 locations: five detectors in each of the four survey areas. At each location recordings were carried out two nights in the period June 24th-26th 2020 and two nights in the period July 12th-14th 2020, from sunset until sunrise. The locations were chosen based on our expert knowledge of the individual species biology, transport flight, feeding behaviour and their use of the landscape. The massive amounts of data were divided into sound files of maximum 15 secund length. These sound files were analysed in Batsound. Number of sound files reflects time of activity and not the number of bats, which is very important to keep in mind when applying our data.Quality Control
