Time series of ring width index (RWI, i.e. Z-scores) of Salix glauca L. from nine sites along the Nuuk Fjord (Southwest Greenland). Rings that evidence Eurois occulta L. outbreaks are found for the years 2003 and 2010 (Iffiartarfik, Sandnes and Austmannadal-1 (V52a)) and 2002 and 2009 (Austmannadal-2 (V53d)¹⁶). These rings have been excluded from the analysis. Data represent the site means and colours identify samples from control (CONT) and past anthropogenic nutrient enrichment (PANE) soils.
