Since 2007, SLU has conducted daily phenology observations on forest trees (birch, Scots pine, and Norway spruce) during the spring at four sites in northern Sweden (Fig. 5, Table 5, ##7.2, 8.2, 13.2, and 14.2) In addition, the phenology of 15 plant species is observed at two sites and of birch at one site, all at Abisko (Table 5, #1.11, and 1.12).
