Soils with roots or root-like inclusions have often been tested in direct shear to quantify the effects of vegetationon the shear strength of soil, and in turn, the stability of slopes. However, a straightforward evaluation of rootreinforcement is challenging due to the complex nature of roots, and the dependency of soil behaviour on manyfactors. An Inclinable Large-scale Direct Shear Apparatus (ILDSA) was built to study the shearing behaviour ofroot-permeated soils. Planted specimens, consisting of two different sets of species, were prepared with amoraine, sampled from a recent landslide location, and tested in direct shear subsequent to saturation.Relationships of peak stress ratio with dry weight of roots, maximum dilatancy angle and void ratio were in-vestigated to evaluate the behaviour of root-permeated soil. The combined approach, of taking both presence ofroots and dilatant behaviour of soil into consideration, results in a more realistic understanding and quantifi-cation of the effects of root reinforcement, at least, for laboratory testing of root-permeated soils
