Rationale:
Soil erosion is seriously threatening ecosystem functioning in many parts of the world. In this context, it is assumed that tree species richness and functional diversity of tree communities can play a critical role in improving ecosystem services such as erosion control. An experiment with 170 micro-scale run-off plots was conducted to investigate the influence of tree species and tree species richness as well as functional traits on interrill erosion in a young forest ecosystem. An interrill erosion rate of 47.5Mgha^-1 a^-1 was calculated. This study provided evidence that different tree species affect interrill erosion differently, while tree species richness did not affect interrill erosion in young forest stands. Thus, different tree morphologies have to be considered, when assessing soil erosion under forest. High crown cover and leaf area index reduced interrill erosion in initial forest ecosystems, whereas rising tree height increased it. Even if a leaf litter cover was not present, the remaining soil surface cover by stones and biological soil crusts was the most important driver for soil erosion control. Furthermore, soil organic matter had a decreasing influence on interrill erosion. Long-term monitoring of soil erosion under closing tree canopies is necessary, and a wide range of functional tree traits should be considered in future research.

Main Experiment: Runoff Plots in the Main Experiment - Data
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...

Main Experiment: Runoff Plots in the Main Experiment - Positions
Abstract:
Different to our proposal we decided not to have 2 runoff plots (1 m² in size each) but 5 Mini-ROPs (40 cm x 40 cm, 0.16 m² each) per VIP. We spread them
randomly over the left (vertical rows 1-4, horizontal rows 5-20) and lower (v rows 1-15, h ...
