Plant and soil variables in plots outside and beneath Salix richardsonii patches along active and abandoned channels in a High Arctic tundra

We explored how erect shrub abundance leads to SOC variation within 20 cm soil cores in a High Arctic tundra (Bylot Island, Nunavut, Canada), where the only erect shrub, Salix richardsonii, has settled along currently active and abandoned channel zones of alluvial fans.
