Waterschap Aa en Maas voert langs de Maas een aantal dijkverbeteringen uit. Eén van die trajecten is het traject van Cuijk naar Ravenstein. Langs dit traject leven er bevers en dassen in de uiterwaarden en binnendijks langs de waterkering. Daardoor zijn er risico’s rond schade aan de waterkering...

De gemeente Den Haag zet vleerMUS in als nulmeting van de populatieomvang van gewone- en ruige dwergvleermuis voor een toekomstig SMP. De monitoring via de vleerMUS methode is in de gemeente Den Haag gestart in 2019. De huidige rapportage omvat de resultaten van de transecten die zijn gereden in...

De ontwikkeling of trend van de populatie is een belangrijke SvI-indicator (Limpens & Schillemans, 2016). De Zoogdiervereniging heeft voor de gewone dwergvleermuis, de laatvlieger en de ruige dwergvleermuis een methode ontwikkelt voor monitoring op populatieniveau in het urbane gebied en/of op het...

De provincies zijn sinds 1 januari 2017 het bevoegd bezag voor de passieve en actieve soortenbescherming in het kader van de Wet natuurbescherming waaronder het beoordelen van ontheffingsaanvragen in het kader van ingrepen in de fysieke leefomgeving en schadebeleid. Bij het al dan niet kunnen...

Provincie Gelderland is verantwoordelijk voor het behalen van de instandhoudingsdoelstellingen van het Natura 2000-gebied Veluwe. Dit jaar gaat de provincie aan de slag met het opstellen van herstelprogramma’s met daarin maatregelen om de natuur op de Veluwe op een toekomstbestendige manier...

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). There was a general decline in bat numbers during...

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. Current predicted climate change may alter...

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. This study investigates whether the ambient temperatures and other characteristics of these...

The winter of 2021 was a special anniversary for bat counts in hibernacula in the Netherlands. It was 40 years after a first overview (in 1980) of the counts in the Netherlands and (almost) 25 years after the start of the National Ecological Monitoring Scheme (NEM) of bat hibernacula, but it was...

Abstract: Twenty six different marl quarries in Flanders are checked annually for hibernating bats, 18 in the Meuse basin and eight in the Scheldt basin. Most of the quarries were created in the second half of the 16th Century through the extraction of marl as a building material and as a raw...

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. The main hibernacula complexes are located in the Natura 2000 dune...

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. Dijkhuizen took place on 28 January 2021 in a small number of accessible bunkers in the Natura 2000 area...

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 Wassenaar and The Hague...

Abstract: Fort Steendorp (east of Temse, East Flanders, Belgium) is a large former military brick fortification, which is nowadays one of the most important bat hibernation sites in Flanders. The fortification is part of two, 19th and early 20th century defensive ‘belts’ of fortifications around the...

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. Bat counts have steadily increased to a maximum of 265 in 2011...

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. In the Netherlands these counts have been done as part of the National Monitoring Scheme...

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. Efforts to reduce carbon...

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). The motivation for this special issue was the legal protection...
