  1. a) Winter (years 1992–2003) and b) summer (years 1992–2014). Statistics show the model averaged results from across the best supported models (listed in Additional file 1: Table S1). T depicts Temperature, R precipitation, DecJan the months of December and January combined, FebMar is February and March combined. SGS indicates the start of the growth season of trees. Significant variables are highlighted in bold font. Results for the month variable (which was set as categorical) are omitted here and are shown in Fig. 2
