Fig. 6. Performance of the HSI model for Capercaillie at larger scales. HSI scores for all sample plots within 100-ha, 400-ha, or 2000-ha areas, respectively, were aggregated into a mean HSI score. The percentage of sample plots within a 100-ha, 400-ha, or 2000-ha areas, respectively, is an index of Capercaillie abundance within that area. Regression lines are based on the logistic models in Table 4. Data points are color-coded for the different study areas.
