High latitude peatlands cover only 3 % of the global land area, yet store up to 30 % of the total soil carbon. In addition to their vital role in the global carbon budget, these ecosystems regulate hydrological and biogeochemical cycles in the boreal landscape. The objective of my research is to quantify landscape controls on vital mire patterns and properties, including mire nutrient regime, plant productivity and peat growth.
I focus on minerotrophic mires in the Sävar Rising Coastline Mire Chronosequence (SMC). The SMC is located in the coastal area north of Umeå, Sweden. In this region, new land is continuously rising from the sea due to strong isostatic rebound (ca 9 mm/year), which has formed a unique natural mire chronosequence that enable studies at the landscape level.
