| الوصف: | In recent years, biodiversity has declined faster than ever before in human history. Appropriate monitoring methods are needed to detect the decline of populations in time to be able to take conservation measures. Information on population dynamics can only be obtained by conducting standardised monitoring programmes, and the quality of the data depends on the survey method used. The present study aims to provide scientifically sound recommendations for the selection of a suitable survey method for emerging flights at greater mouse-eared bat (Myotis myotis) maternity roosts. For this purpose, three survey methods, namely infrared video recordings, counting by light barriers and visual counting of emerging bats, were used simultaneously for 4–5 nights at three different maternity roosts in 2019 and comparatively evaluated. Besides the quality of the counting data, the requirements and limitations of the different methods were compared and discussed. The results of this study showed that the number of emerging flights detected with all three survey methods were closely correlated, regardless of location, number of emerging flights per night (between 300 and 800) and season. Furthermore, it was shown that the presence of the observer and infrared video recordings had no significant influence on the emergence behaviour of the bats recorded by light barriers concerning the time of emergence, the duration of activity and the number of counts. As the three methods differed with regard to additional parameters, such as the need for technical equipment or qualified personnel, the time required, the costs and the error-proneness individual settings and requirements should be taken into account when deciding about the method used. However, for the continuous monitoring of greater mouse-eared bats at their maternity roosts, which is part of the monitoring requirements under the European Union Habitats Directive, the use of light barriers proved to be the method of choice, in particular as it allows to promptly detect changes in the bats’ activity as a basis for conservation measures. |
