%X Three feral pig populations inhabiting contrasting environments along the north easterncoast of Australia have been investigated with respect to population structure, individual condition andreproduction. The population on Prince of Wales Island contains a large proportion of juvenile andsub-adult pigs but lacks pigs in the higher age classes. Individuals also breed at an earlier age thananimals of the mainland populations. Pig populations on Cape York Peninsula show a largerproportion of older animals and feral pigs living in rainforest habitats show a low proportion ofanimals in very young and very old age classes. Pigs from the lowland rainforest population are inbetter condition than those of the other populations for most of the year, reflecting the availability offood all year round in this environment. Differences in the population structure of the threepopulations are discussed with respect to fecundity and several mortality factors such as predation anddiseases/parasites.
