The 4th German national report required by the EU Habitats Directive was initially submitted to the European Commission on 2 July 2019 and finally, in its revised version on 30 August 2019. The main results of the report are documented in this publication. A double-page for each habitat type summarises the following essential information for the bi...

Biodiversity hotspots in Germany - Selection and demarcation as a basis for the federal programme in support of the national biodiversity strategy
To provide a basis for the nationwide programme on biological diversity, the biodiversity hotspots in Germany were identified. This work was conducted as a publicly-funded research & development project....
The National Biodiversity Strategy (NBS) contains a set of 19 indicators. Reporting on successes and failures of the strategy will be based on the outcome of these indicators. The indicator set covers topics that are politically relevant for the conservation of biological diversity. The original set has been revised and complemented by indicators c...
In order to realise a nationwide ecological network of habitats as prescribed by the German Federal Nature Conserva - tion Act (Bundesnaturschutzgesetz, Articles 20 and 21), a working group of relevant Länder authorities has cooperated with the Federal Agency for Nature Conservation BfN to produce a system of criteria which can be used to identify...
The songflight and the territorial behaviour of courting male pipistrelles (Pipistrellus pipistrellus) were observed in an urban habitat of this bat species, in the city of Bayreuth in Bavaria. (1) Within the city limits, from the middle of July to the end of October but most intensively in September, the male bats occupied courtship territories av...
Testing the suitability of evaluation sheets for FFH monitoring Summary The monitoring of the FFH-species and -habitats in Germany bases upon evaluation sheets developed by specialist working groups. I tested the suitability of the sheets by an example of a hypothetical Pelobates fuscus population. 15 participants of an European workshop about this...

... Due to a rather cool and wet climate (mean annual temperature: 7.7°C; mean annual precipitation: 1 336 mm; meteorological station Bad Kohlgrub [742 m a.s.l.]; period: 1992-2019; DWD, 2020), numerous mires developed in the valleys and hollows (Succow & Jeschke, 1990;Bayerisches Geologisches Landesamt, 1996). Today, the study area contains one of the largest networks of mire ecosystems in Central Europe with an outstanding value for biodiversity conservation and, hence, belongs to one of the German biodiversity hotspots (Ackermann et al., 2012;BfN, 2012). ...

... Verhören zur falschen Tages-oder Jahreszeit oder bei ungeeigneter Witterung kann zudem dazu führen, dass die Knoblauchkröte gänzlich übersehen oder fälschlicherweise eine zu geringe Populationsgröße angenommen wird. Dies kann im Hinblick auf das Monitoring der Art z.B. im FFH-Kontext nicht deutlich genug betont werden (Sachteleben & Behrens 2010, Behrens et al. 2009a Nachdem in den letzten Jahren im Umfeld der Gewässer die Ackernutzung extensiviert werden konnte (u. a. durch Blühstreifen), entwickelt sich die stark schwankende und oft unzureichende Wasserführung der beiden Feldsölle zum wichtigsten lokalen Gefährdungsfaktor. ...

... Das Konzept basiert auf einer so genannten verbundenen Stichprobe mit festen Untersuchungsflächen. Hierbei werden in jeder Berichtsperiode die gleichen Vorkommen untersucht. Dieses Vorgehen vermindert einerseits den Aufwand der Flächenziehung und andererseits wird eine höhere Trennschärfe bei statistischen Analysen mit den Rohdaten erreicht(Weddeling et al. 2007). Als Untersuchungsfläche sollen in der Regel ganze Vorkommen abgegrenzt werden. ...
... The so-called 'invasion' behaviour of common pipistrelle bats during the swarming time in late summer and in autumn (note that the original term 'autumn invasion' in not used here as in the context of biological invasions (e.g., Simberloff et al. 2013), possibly one may rename it as 'incursion') has been described as a remarkable species-specific ecological trait (Sachteleben 1991). These invasions represent the flight of numerous groups of individuals into unoccupied or inhabit-ed buildings and similar human-made spaces, which are often unsuitable as roosts in general and can act negatively as ecological traps (e.g., Palášthy and Gaisler 1965;Sachteleben and von Helversen 2006). As revealed from a recent review, such an unusual behaviour of this species is limited within its range to several cities of Central Europe (mainly Germany, Czechia, Slovakia; Nusová et al. 2019a). ...
