Habitat preferences of the endangered diving beetle Graphoderus bilineatus: implications for conservation management

Original language description

Populations of the endangered diving beetleGraphoderus bilineatusare decreasing across Europe. Evidence-based conservation of its local populations requires good knowledge of its habitat requirements, but data from different countries are often incomplete or contradictory. Graphoderus bilineatuswas common until 1950s but then almost disappeared in the Czech Republic. Using data from a recent field survey in its core distributional area in the Czech Republic, we evaluate its habitat preferences at the habitat and microhabitat scale. We found that extensively managed fishponds can provide similarly suitable habitats forG. bilineatusas do more natural habitats including floodplain and sandpit pools, while the species is typically absent in intensively managed fishponds. All else being equal, the species is more likely found in larger water bodies surrounded by other wetlands and is more often absent at sites in agricultural landscape. We detected only weak preferences on the microhabitat scale. They suggested thatG. bilineatustends to occur in deeper water but closer to the shore and in microhabitats dominated byGlyceriaorTypha. These microhabitat associations partly differ from those reported from other countries. Moreover,G. bilineatuswas found at localities with higher species richness of large-bodied aquatic beetles, both common and threatened, supporting the species status as an umbrella species for other aquatic macroinvertebrates. Our findings provide guidelines for conservation management of currently known localities and other potentially suitable sites, including the creation of new ones. Finally, our study reinforces the Annex II species status ofG. bilineatusin the Habitats and Species Directive.
