    Abstract

    Spatial modelling approaches are increasingly used to design and direct management and conservation plans at the landscape scale. One of the main developments is buffer-radius approaches that use information on the dispersal ability of species to create buffers around distinct habitat patches to assess habitat connectivity within the landscape. In this study, Euclidean and least-cost buffers were used to predict functional ecological networks for wood cricket (Nemobius sylvestris) within the wooded landscape of the Isle of Wight, UK. Compared to the Euclidean buffer approach, the least-cost method revealed a higher number of functional networks indicating a high level of habitat fragmentation for wood cricket and similar woodland invertebrate species. Recent habitat network development increased network connectivity in 3 out of 4 cases. The results further highlight the demand for detailed information, both in terms of species specific and in terms of land cover data, for using least-cost modelling tools effectively in conservation planning.
