Abstract

Here the impact of landslides on organic carbon (OC) cycling in 13 river catchments spanning the length of the western Southern Alps, New Zealand is assessed over 4 decades. Spatial and temporal landslide maps are combined with the observed distribution and measured variability of hillslope OC(modern) stocks. Comparison with published estimates of OC(modern) export in river suspended load suggests additional erosion of OC(modern) by small, shallow landslides or overland flow in catchments.In addition, it was found that landslides caused rapid turnover of the landscape. Landslide-OC(modern) yields and rates of turnover vary between river catchments and appear to be controlled by gradients in climate (precipitation) and geomorphology (rock exhumation rate, topographic slope
