At this moment there is a gap in information regarding the affect roots might have on ²¹⁰Pb distribution in peat cores and in turn the obtained chronologies by ²¹⁰Pb dating.

Therefore, four peat cores were collected from the snow manipulation study site within the mire complex Storflaket (68°20048″N, 18°58016″E). Two cores from snow fence plots, which has experienced root growth due to permafrost thaw, and 2 cores from control plots. ²¹⁰Pb distribution and the provided ²¹⁰Pb chronologies were then compared with root content within and between the cores. In two of the cores (C5 and SF2) did subsurface peaks in the ²¹⁰Pb activity profile follow the distribution profile of the dwarf shrub roots. The same pattern was not seen with Eriophorum roots.

This indicates that presence of dwarf root with their shallow and horizontally growth can affect the ²¹⁰Pb profile by horizontal translocation of ²¹⁰Pb. The chronologies obtained by the CF:CS and CRS dating models could not be validated for the C5 core which suggest that dwarf shrub roots also can affect the ^21oPb dating.
