Behaviour, genetics, and protection of urban and suburban hedgehogs
This project aims to investigate whether rural and urban hedgehogs or different urban populations differ in lifestyle. Furthermore it focusses on whether and how concentrated human activities influence the behaviour of urban hedgehogs.

The populations of hedgehogs (Erinaceus europaeus) are steadily decreasing across Europe, although recent studies have shown that these nocturnal and protected animals have higher population densities in urban or suburban areas than in rural areas. The research project is investigating the extent to which hedgehogs adapt their way of life to the conditions of a big city and is intended to provide concrete recommendations for the effective linking of nature conservation measures and urban land use planning.
By the genetic analysis of a large number of hedgehogs, for example, we test the hypothesis whether the Berlin hedgehog population is genetically structured into small sub-populations due to numerous inner-city barriers (Department of Evolutionary Genetics). If this is true, the urban structures that act as barriers will be identified.
Some basic questions in this project are:
- In which habitats does the hedgehog occur in Berlin and in which not?
- Are there genetically isolated island populations or corridors between individual hedgehog populations?
- Are there differences in the food spectrum, parasite load, constitution, reproduction rate, mortality between "city and rural hedgehogs" or between hedgehogs in different city habitats?
- How do the warmer urban conditions influence the hibernation behaviour of the hedgehog?
- How do the concentrated human activities influence hedgehog behaviour (e.g. is there increased night activity or an interruption in hibernation)?
The project is in close dialogue with Berlin authorities, associations, citizens and various interest groups.
