The Abisko-Stordalen Palsa Bog station (with ICOS code SE-Sto) is located 10 Km east of the town of Abisko in the 1100 Ha nature reserve of Stordalen. The area is located at the 0°C isotherm which causes the permafrost in the mire to be of sporadic and of very dynamic nature. As a result of recent years warming in the area permafrost has been observed to degrade in many parts of the mires. The site is a mixed palsa-mire underlayed by sporadic permafrost under rapid degradation. Vegetation in the mire consists of sedges and sphagnum mosses in the wet parts and lichens and dwarf birch in more elevated parts of the mire.
