Summary
Phenology monitored at the four Experimental Forests that are staffed.
Project details
General plant phenology is monitored weekly in the concept of Natures Calendar (https://www.naturenskalender.se). This monitoring has been ongoing since 2008, as part of the collaboration within the Swedish National Phenology Network (SWE-NPN).
Intensive forest phenology is monitored weekly during the growing season on birch, spruce and pine trees, including measurements of bud and leaf/shoot lengths, and also the abundance of flowers, unripe and ripe berries on bilberry and lingon-berry plants. This monitoring has been ongoing since 2006.
In this project is also included to assess the ripe bilberries and lingon-berries on the plots that former were used for berry forecasts (9-10 0.25 m² plots at 6 locations within each experimental forest). The berries are picked and assessed with fresh wheight. Resulting fresh wheights are delivered to the NFI, for the estimates of the amount of billberry and lingon-berry in the Swedish forests, published in the annual National Forest Statistics.
