Nederland staat, net als de andere (Europese) landen, voor een energietransitie. Hiervoor wordt breed ingezet op het opwekken van hernieuwbare energie op land (windenergie, zonnepanelen, zonneparken en geothermie) en zee (overwegend windenergie). Ook wordt aan energiebesparing gewerkt.

Abstract: This paper describes the trend of bats hibernating in marl quarries in the south of Limburg, the Netherlands, since 1986 and puts it into perspective by comparing it with the trend between 1940 and 1980, as described earlier by Daan (1980).

Abstract: Hibernation site selection by bats depends on various environmental and physiological factors, microclimatic conditions, and species-specific requirements. For successful overwinter survival, efficient use of stored fat reserves is crucial.

Abstract: The Dutch dune areas between Zandvoort and Bergen aan Zee contain various sites, such as bunkers and ice cellars, in which bats hibernate. The bats in these sites are counted annually each winter.

Abstract: Hibernating bats along the coast of the Dutch provinces of Noord-Holland, Zuid-Holland and Zeeland are described from the first counts in the early 1960s until the winter of 2020, with an emphasis on trends since 1990.

In response to a number of reports of break ins at various places along the coast of Zuid-Holland, an enforcement check by Buitengewoon Opsporings Ambtenaar (BOA / community service officer) J.A.

Abstract: Since the winter of 1977, the populations of hibernating bats have been monitored in five complexes of bunker corridors of the former Atlantic Wall remaining from World War II in the dune areas of Meijendel and Uilenbosch, which are located in the municipalities of Wass

Abstract: This article discusses the results of 35 years of research (1986-2020) on hibernating bats in the Amsterdamse Waterleidingduinen (Amsterdam Water Supply Dunes; AWD), the Netherlands. About 70 bunkers are surveyed every January.

Abstract: Bats have been studied in their underground winter quarters in the Netherlands (and Flanders) since the 1930s. Over time, the focus has shifted from ecological and physiological research to monitoring.

Abstract: Common pipistrelles (Pipistrellus pipistrellus) congregate in mass-hibernacula, sometimes with hundreds to thousands of individuals. In the urban environment, these hibernacula are often situated in crevices and other spaces in buildings with poor insulation.

Forty years ago, a collective of authors described the population trends of a number of bat species in the Netherlands in a special issue of Lutra: ‘The Dutch bats: population trends in winter and summer roosts’ (Daan et al. 1980).
