This study, carried out in the Paramo de Guerrero (Cundinamarca, Colombia) aimed at quantifying the fog interception capacity by the paramo vegetation (Weinmannia spp, Gaiadendron punctatum, Espeletia grandiflora and Holcus lanatus); and to make a continuous monitoring of the soil surface water content, in order to determine the net inputs to the ecosystem, as the amount o fog water that is incorporated to the system. For this we exposed to fog events branches of main vegetation types in this paramo, registering the gain or loss of water, by measuring the differences in weight before and after the fog event. Fog inputs were also measured through fog gauges (harps and cylinders). Measurements of fog interception (ml) were translated in water depth, using the LAI, the dry biomass and the volumetric water content. In general, the vegetation types used in this experiment showed a differential behavior to capture fog water, which was associated to the intensity of the event, except for the pasture that was more efficient to capture water from the fog events, but this was not related to the density of the fog event. Soil water content slightly increased during some fog events, implying a net input of fog water to the ecosystem. Comparisons of direct measurements of the amount of water captured by the vegetation types, with that intercepted by fog gauges (harps and cylinders), showed significantly differences, being larger the amounts captured by fog gauges.
