Appendix E. Correlation between forest responses to the first and second droughts.
Fig. E1. Correlation between first (ΔNDVIfirst=NDVI2000-NDVI1998) and second (ΔNDVIsecond=NDVI2011-NDVI2005) droughts effect. Colors express pixels count within a given 0.01 * 0.01 ΔNDVI combination. A weak negative correlation was found between the effects of both droughts (Pearson correlation coefficient = -0.08, p < 0.001). Note that the correlation coefficient was calculated based on raw data, while aggregation to 0.01 * 0.01 ΔNDVI combinations is shown in the figure for easier interpretation.
