Table 1

Mann-Kendall test of monotonic temporal trend for the 25, 50 and 75^th percentiles of annual FBI score for each network, along with the annual percentage of sites in ‘good’ condition (pc_good) according to the index (index condition class “Good”). The columns correspond to the Mann-Kendall test p-value (mk_pvalue), Sen-Theil slope (sens_slope), slope significance (sig) and trend interpretation (trend). Note that (1) a degradation involves a positive slope in the percentiles, but a negative one for ‘pc_good’, and (2) when analyzing REPNET from 2013 to 2023 the 50 and 75^th percentiles show significant tendencies toward sites degradation.
