Fig. 6

B-C plots for species abundance data, six habitat types. Symbol diameters are proportional to the TBI statistics. In all habitat types except group 4, the green line is above the red line, indicating that species losses dominated gains from 1985 to 2015. In group 4 (the swamp) on the contrary, the red line is above the green line, indicating that gains dominated losses in this habitat. See Fig. 5 where the construction of the green and red lines is described. Symbol fill colours correspond to habitat types; habitat colour codes are the same as in Fig. 1
