Table 2. Concordance in threat score between experts measured by Kendall’s concordance coefficient (W) for each threat category (see Table 1).
Concordance was calculated for threat scores individual species (‘Species’), and for Tmean for species defined into groups based on taxonomy (‘Taxonomy’), main nesting habitat (‘Habitat’) and European threat status according to BirdLife’s categories of conservation concern (‘SPEC’). Coefficients are significantly different from 0 at P = 0.00125 (i.e., the Bonferroni adjusted significance level) unless given in parentheses. N = 19 for each coefficient.
