Badger Meles meles as Ecosystem Engineer and Its Legal Status in Europe

SIMPLE SUMMARY: The European badger, listed in Bern Convention (protected fauna species), is also known as an important ecosystem engineer that creates new microhabitats among its setts suitable for the establishment of many plant and animal species. Badger setts are areas with topsoil disturbance and hence are places with higher species diversity than undisturbed surroundings. Much new data concerning the importance of badgers in ecosystem engineering indicates that the way badger populations are managed in Europe should be reconsidered. Thus, the aim of this study was to review the impact of badgers on shaping of species diversity in forest ecosystems with special attention to their legal status across Europe. The badger is hunted on 69.3% of the continent for 1.5–12 months per year. The real problem with management of this species concerns a quarter of its range in Europe, where the species can be hunted in winter and spring during mating season and during parturition. Reducing the hunting season to a maximum of three months in late autumn (September to November) seems to be a better approach. To prevent the negative effects of overhunting, special attention should be paid to population monitoring. ABSTRACT: The European badger plays an important role as a natural factor shaping species diversity in forests. Its extensive setts can be used by many other animals as shelters. Soil perturbations in their setts support plant communities that differ from the matrix landscape. The badger is also an effective seed disperser. We investigated its role as an ecosystem engineer in preserving species diversity and discussed its legal status across Europe. In most European countries (69.3% of the continent), the badger is hunted, sometimes year-round. The hunting season lasting through winter until early spring may have a negative effect on badger populations, especially when cubs are born in February. Although this species is Red Listed in 19 European countries (with categories ranging from LC to EN), the badger is strictly protected by law in 30.7% of its European range. A reduction in badger populations may limit its ecosystem services (seed dispersal, topsoil disturbances, microhabitat creation). Much new data on the importance of badgers in ecosystem engineering has allowed us to reconsider how we manage badger populations.
