Modelling bird habitat suitability based on landscape parameters at different scales
چکیده انگلیسی
Habitat suitability as characterized by the presence of a species and by reproductive success was modelled in relation to different parameters of landscape diversity at different scales. Parameters characterizing landscape pattern were determined for the UTM 10 km × 10 km cells covering the whole of Estonia and were correlated to the distribution of over 30 forest bird species. The landscape parameters include areas of lakes, mires and built-up areas, length of borders between different land cover units and length of selected line elements, share of different kinds of forest and peatland. The bird species are grouped by correlation into three major groups: (a) independent, (b) wetland preferring (with subgroups of those avoiding built-up areas and roads and those not) and (c) built-up area dependent (with subgroups depending on the importance of line elements). For selected predator species, nesting success was related to landscape parameters on a finer scale, using cells of 10 km2. Land pattern was characterized by total length of line elements (streams, roads, borders, ecotones) and certain areal coverage (forest, mires, fields, built-up areas) within the cell. The impact of variations of food availability was linked to the relation. Possibilities for downscaling and upscaling of relations determined at different scales and areal coverage are discussed.
