    Abstract
    During the period from 1/1/70 to 24/6/71, 150 hedgehogs were marked and 356 resightings were recorded in a study area covering 16.28 hectares of pasture and trees. Population size and density are estimated and the seasonal changes in activity are described. The sex ratio of the population and the apparent changes in this ratio due to behavioural dimorphism between sexes are discussed in relation to the body weights of the animals and to hibernation and breeding season. No detailed age structure is presented for the present population. The breeding season and the number and size of the litters are discussed, as are the causes of mortality in the population. Dispersal of the population is seen as an important demographic parameter, and the sexual and seasonal influences upon movement are discussed. Home ranges are investigated using two statistical methods; the convex polygon method and a probability ellipse method. The shape and size of individual's ranges are described using the first method, while the second method is used to describe synthesised ranges for males, females and Juveniles. The nest site and food locations are discussed in terms of foci of activity, and seasonal changes in movements were investigated and an argument is advanced on the hedgehog's territorial behaviour and social structure.
