Chronological Interpretation Europe


The European #forestconditionmonitor shows a heterogeneous year 2021: the late season-start entailed low greenness values in large parts in spring, the precipitation during summer indicates a relaxation of the last year’s drought stress. Finland’s forests suffered some drought.


Peak season (end of July) NDVI indicates a heterogeneous pattern across Europe. While parts of Central Europe featured a relaxation of the drought of the previous three years due to extensive precipitation, parts of Scandinavia featured low quantiles, possibly due to a relatively warm and dry summer. At the same, parts of the Mediterranean (in particular Italy, Balkan) also featured relatively low NDVI values, reflecting the extraordinary heatwaves of summer 2021 which negatively affected forests.


The EFCM has undergone a major update, now depicting forest greenness over the whole year in dependence of local average growing seasons and in WGS84 geographic projection. In April/May 2021 large parts of Central and Northern Europe featured relatively low greenness, which reflects an extraordinary late start of the growing season and thus a delayed phenology. The next update of the EFCM is scheduled for early in October 2021 then also including the summer season 2021 in which large parts of Southern Europe suffer from heat, drought, and forest fires.
