title: The distribution of the hedgehog (Erinaceus europaeus L.) in Finland in 1975.
abstract: 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.
