Comparison of the observed I. ricinus abundances from 2016 and 2017. Observed summed I. ricinus abundances for the year 2016 plotted against the summed abundances for the year 2017 for the 18 sites that were revisited in 2017. (a) Larvae, (b) nymphs, (c) adult males, (d) adult females. The black line depicts a 1:1 relationship between counts from 2016 and 2017. Spearman’s rho above each graph depicts the results from the Spearman Rank correlation. Not all points are visible as some counts had the same value in 2017 as in 2016 (for example, 8 sites had zero counts of adult males and females for both 2016 and 2017; this number was 4 and 3 for larvae and nymphs, respectively).
