The distribution of the hedgehog (Erinaceus europaeus L.) in Finland in 1975.
The distribution of the hedgehog (Erinaceus europaeus L.) in Finland was surveyed in the light of an inquiry. The range presented is based on more than one thousand answers to a questionnaire. The extension further northward of this species during the past ten years was confirmed. The distributional areas of the hedgehog in Finland in 1952, 1965 and 1975 are presented in a cartogram. In southern Finland the number of the hedgehog has clearly decreased during the past ten years (1965-1975). Some possible reasons for the decline are discussed.
