  abstract = {{O}wing to their high water retention, the volcanic ash-soils of the {N}orthern {A}ndean highlands (páramos) can be considered as natural 'water storage tanks' for drinking water and for irrigation. {V}egetation plays an important role in transferring rain to the soil and in controlling the soil water content. {T}o assess this role, we quantified the stemflow process under rainfall simulations for seven of the main plants along an altitude gradient on the {P}ichincha volcano in {E}cuador. {T}he volume of water transferred into the soil was higher at the lower rainfall intensity than at the higher intensity. {T}he results were compared to the stemflow measured with potato and maize crops growing in the lower altitude range. {T}he results showed that the relative volume of stemflow increased with altitude from 8% in the crop area to 58% in the upper part of the catena. {L}ow values of stemflow were associated with potatoes and maize annual short-cycle crops while high values were associated with the natural vegetation. {F}or cultivated crops rainwater interception by stemflow delayed the soil surface crusting and runoff process. {T}his study shows that rainwater interception by vegetation is of great importance for soil water recharge in these {A}ndisols.},
