Stabilisation effects of plants are developing as a function of time. Within this scope, soil aggregation processes play a decisive role in re-establishing a protective vegetation cover. From this perspective we compared bare and vegetated soil, on the one hand artificially prepared and, on the other hand, derived from a recently landslide affected slope and an adjacent gully with 25 year old eco-engineering measures, respectively.
In both cases, the planted specimens had a significantly higher soil aggregate stability compared to their respective control samples, with the relative increase from control to planted equal for both the natural and artificial samples.
Aspects of the development and succession processes of plants are compared as well as rooting and the degree of mycorrhization. Additionally, soil development and the methodical approach are discussed as well as a new approach to modelling soil aggregate stability in respect of eco-engineering measures for slope stabilisation presented.
