Abstract:
In soil erosion research it is widely accepted that vegetation is a key factor for the type and intensity of erosion. Thus, scientists have long recognized the importance of forests for erosion control and afforestation is a common measure of soil protection. However, the mechanisms how forests protect the soil remain debated and especially the role of biodiversity is unclear.
In this experiment we quantified the initial soil erosion under forest using micro-scale runoff plots (ROPs, 40 cm x 40 cm). 70 study plots have been equipped with 5 ROPs each (350 ROPs in total). The study plots represent different levels of tree diversity ranging from 1 to 24 tree species mixtures and bare ground. The measurements took place during the rainy season from May to June 2013 with rainfall events showing intensities up to 85 mm h-1. We measured sediment discharge, runoff volume, soil surface cover and canopy cover in the field. In addition, organic carbon and nitrogen contents in eroded sediments were analysed.
Design:
350 runoff plots on 70 VIPs covering tree diversity levels from 0 to 24.
