The conservation concept, "Capercaillies in the Bavarian Forest"Comprehensive collation of data allows a rough estimation of the fortunes of the Capercaillie population in the Bavarian Forest during the past 150 years. Historical data indicate the range of the species and the spatial development of the population at different periods and altitudes.By means of digital recording of potential habitat at present from aerial photographs, comparisons could be made between actual and potential occurrence based on suitable woodland structures. The types of woodland structures still occupied by Capercaillies thus become evident, as do those areas in which it could become re-established.Recent Capercaillie occurrences were predominantly from the higher altitudes and ridges of the Bavarian Forest. For climatic reasons, these areas are not profitable for commercial forestry, are relatively free from visitor pressure, and so remain comparatively undisturbed.By analysing mapped potential habitats together with occurrences of Capercaillies, the core distribution areas can be delimited and targeted for protection. Oil the basis of data processing, present and future habitats available to Capercaillies were more effectively identified.In terms of practical forestry, general protection can be improved by targeted calming of lek sites and roosting areas through consultation with forest owners and managers.By overlaying paths, tourism and leisure facilities and usage onto potential habitat areas, existing conflict areas can be specified.
