    <subfield code="a">&lt;p&gt;The influence of vegetation on slope stability is well understood at the slope level but scaling up to the catchment&lt;br&gt;
level is still a challenge, partially because of a lack of suitable data to validate models. We tested the physical&lt;br&gt;
landslide model, LAPSUS_LS, which models slope stability at the catchment scale. LAPSUS_LS combines a hydrological&lt;br&gt;
model with a Limit Equilibrium Method model, and calculates the factor of safety of individual cells&lt;br&gt;
based on their hydrological and geomorphological characteristics. We tested two types of vegetation on slope&lt;br&gt;
stability: (i) coffee monoculture (Coffea arabica) and (ii) a mixed plantation of coffee and deep rooting Erythrina&lt;br&gt;
(Erythrina poeppigiana) trees. Using soil and root data from Costa Rica, we performed simulations to test the&lt;br&gt;
response of LAPSUS_LS to root reinforcement, soil bulk density, transmissivity, internal friction angle and depth&lt;br&gt;
of shear plane. Furthermore, we modified the model to include biomass surcharge effect in the calculations.&lt;br&gt;
Results show that LAPSUS_LS was most sensitive to changes in additional cohesion from roots. When the depth of&lt;br&gt;
the shear plane was fixed at 1.0 m, slopes were not unstable. However, when the shear plane was fixed to 1.5 m,&lt;br&gt;
the mixed plantation of coffee and trees stabilized slopes, but the coffee monoculture was highly unstable,&lt;br&gt;
because root reinforcement was low at a depth of 1.5 m. Soil transmissivity had a limited impact on the results&lt;br&gt;
compared to bulk density and internal friction angle. Biomass surcharge did not have any significant effect on&lt;br&gt;
the simulations. In conclusion, LAPSUS_LS responded well to the soil and vegetation input data, and is a suitable&lt;br&gt;
candidate for modeling the stability of vegetated slopes at the catchment level.&lt;/p&gt;</subfield>
