The SITES infrastructure offers researchers access to phenological measurement series from intensive programs of forest trees and berries, plants and migratory birds. Many stations are also members of and report to the Swedish Phenology Network (SWE-NPN).
Read more about what the Abisko, Asa, Erken, Grimsö, Röbäcksdalen, Skogaryd, Svartberget and Tarfala stations can offer you as researcher.
ABISKO
Phenological measurements are carried out in Abisko of plants and migratory birds.
Abisko field research station is a member of the Swedish Phenology Network (SWE-NPN).
ASA
Asa participates in several activities in the phenology field. Within forest phenology, there is intensive measurements of phenological processes in the most common forest trees and berries. In Asa research park, ten plots are dedicated to careful measurements of growth in young spruce forest. Stem growth and litterfall are measured weekly, as well as groundwater depth and soil moisture on the plots during the growing season.
Asa also has a web camera that is part of the PHENOCAM network. Images are recorded for ash, aspen, birch and a grass plot. The results from the camera can be used to calculate actual growing seasons.
Measurements also takes place within general plant phenology, where the observations are reported to the Swedish Phenology Network (SWE-NPN) nationwide database ‘Nature’s Calendar’.
ERKEN
At the Erken laboratory, cycles for nutrients, microbe communities and phytoplankton in lakes are measured.
The Erken laboratory reports phenological data about land plants to the Swedish Phenology Network (SWE-NPN).
GRIMSÖ
Grimsö’s continual wildlife and forest programs includes phenological measurement series for plants and migratory birds.
Grimsö is a member of the Swedish Phenology Network (SWE-NPN).
RÖBÄCKSDALEN
Röbäcksdalen is a member of the Swedish Phenology Network (SWE-NPN).
SKOGARYD
Skogaryd is a member of the Swedish Phenology Network (SWE-NPN).
SVARTBERGET
Berry forecasts and field observations of selected plants are examples of Svartberget’s environmental analysis of changes in vegetation, forest status, soil and water conditions, and climate. From May to October, there are weekly observations and measurements for birch, spruce and pine, and blueberries and lingonberries. On the trees, bud and shoot development is measured, along with autumn colours and leaf fall, and on the berry plants, the focus is on flowers, unripe and ripe berries. Data is available from 2006. Together with the Swedish National Forestry Inventory and the Asa station, annual forecasts are made of bilberry and lingonberry supply in Swedish forests.
Svartberget is a member of the Swedish Phenology Network (SWE-NPN).
TARFALA
Tarfala offers opportunities to study phenology from the tree line (approximately 700 m asl) up to glaciers and snow fields (approximately 1200-2000 m asl). Phenological measurements are carried out using vegetation plots.
Tarfala is a member of the Swedish Phenology Network (SWE-NPN).
The Swedish Phenology Network (SWE-NPN) is a collaboration between universities, environmental monitoring agencies, and volunteers. Many field research stations, botanical gardens and naturum visitor centres, together with many volunteers, participate in the observation network. The Swedish University of Agricultural Sciences (SLU) is principal. The aim is to collect, manage and present long-term data about ‘Nature’s Calendar’. When observations are reported to the ‘Nature’s Calendar’ website, priority is given to around 30 herbs, grass and brushwood, and around 20 trees and bushes. Historical data is available from as long ago as 1873. ‘Nature’s Calendar’ is also starting to collect bee and bird data to supplement the plant phenological observations.
