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.
根据一项调查对刺猬（Erinaceus europaeus L.）在芬兰的分布情况进行了研究。给出的分布范围基于对一份问卷的一千多个回答。证实了该物种在过去十年中向北扩展的情况。以图表形式展示了1952年、1965年和1975年刺猬在芬兰的分布区域。在芬兰南部，刺猬的数量在过去十年（1965 - 1975年）明显减少。讨论了数量减少的一些可能原因。
