Ecology
Description and characteristics
Erinaceus europaeus is a mammal of the family Erinaceidae, known as the only spiny mammal in the United Kingdom. Its distribution covers much of western and central Europe, including the British Isles, Mediterranean islands, southern Scandinavia, Estonia, and northern Russia. It is a generalist species that adapts to various environments, from rural landscapes to urban and peri-urban areas.
Regarding its habitat, it prefers areas with shrubs, hedges, and forest edges, although it also inhabits meadows, scrubland, and cultivated land, showing a preference for humid zones in Atlantic and Mediterranean regions. In the United Kingdom, it is common in gardens, parks, and farmland, although it avoids intensive agricultural lands due to food scarcity.
Its diet is omnivorous, consuming mainly invertebrates such as snails, millipedes, earthworms, beetles, and caterpillars, as well as fruits and fungi. Its activity is predominantly nocturnal and terrestrial, relying on its acute sense of smell and hearing. It is a mostly solitary species, interacting socially only during reproduction or foraging.
The life cycle is marked by winter hibernation. Reproduction occurs between April and September, with litters of four or five young that the mother raises alone. Young born late in the year have less chance of reaching the weight necessary to survive hibernation. In terms of conservation, the species has experienced significant declines in rural areas of the United Kingdom, attributed to habitat loss, road mortality, and prey scarcity, which has led to its classification as Vulnerable at the national level in the United Kingdom and Near Threatened globally.
