Mammals of Tasman Peninsula and their interaction with Europeans

Abstract

Twenty-eight species of terrestrial native mammals occur on Tasman Peninsula. This represents 82% of the total number recorded for Tasmania, which is extremely high given the small area and insular nature of the peninsula. The range of habitats present (ie. both wet and dry forests, heaths and coastal lagoons) is probably the main reason for this high diversity of mammals. Because of high relief, clearing of land has created a mosaic of habitats. The large area of ecotone between forest and pasture has benefited the larger herbivores. Populations of the larger carnivores, the Tasmanian devil and the eastern quoll, have been dramatically reduced probably as a result of eradication campaigns. The insular nature of the peninsular may have helped to ensure that the carnivore population remains low. Of the marine mammals, one species of seal, the Australian fur seal, is resident in waters off the peninsula and two other species are occasional visitors. Nine species of cetaceans have been recorded stranded on beaches around the peninsula, with Eaglehawk Neck having the greatest number.
