About This Field Site

Storflaket is a permafrost plateau peat bog on the southern shore of Lake Torneträsk six km east of Abisko. Together with Stordalen, it is one of the main sites of studying permafrost and palsas and the effects of global warming on permafrost, like increased greenhouse gas emissions.

The Storflaket mire covers about 13 ha and is located along a valley bottom within a hydrological catchment, roughly in the middle of it. The mire is connected via bordering streams to catchment flows. The mire is characterized by relatively thin peat layer (50-90 cm) underlain by silty sediments. A wet zone crosses the mire, dividing Storflaket into two parts where each part is dry, but with shallow ground settings that contribute to a variation in soil moisture.

The plant community consists mainly of dwarf shrubs, sedges, mosses and lichens, and ranges from dry heath vegetation in the upraised dryer parts to moist tussock vegetation in the depressions.
