Fig. 2From: Recent growth changes in Western European forests are driven by climate warming and structured across tree species climatic habitatsRelative change in stand BAI and temporal anomalies for the 8 species under study over the period 1980–2007. The period covered corresponds to median increment years 1982–2005. Bootstrap fits are represented in light grey (trends, Eqs. 5 to 7) and dark grey (anomalies). Unique solid lines represent the species trends (dark grey) and anomalies (black) averaged over the 500 bootstrap fits. Dotted lines represent the 95% bootstrap bilateral confidence intervals for BAI changes. These changes range between +42% (P. abies) and −17% (Q. pubescens). Not significant for P. sylvestris and Q. robur Back to article page
