Trends in perennials (a) M12, (b) AOT40 and (c) W126 for 1995–2014. Data are for changes in the 6-month period relevant for perennials, and are presented as the proportion of non-urban monitoring sites in different regions and countries with trends that: are significantly increasing or decreasing (p ≤ 0.05); show an indication of an increase/decrease (0.05 < p ≤ 0.1); have a weak indication of an increase/decrease (0.1 < p ≤ 0.34), or no change (p > 0.34). Blue colours indicate decreasing trends, green colours no trend and red colours indicate decreasing trends. Colours have been selected to match the arrows in Figures 16, 17, 18.
