The provision and regulation of water flows in catchments is probably the most important ecosystem service cloud forests; however, its hydrological behavior impacts associated with forest conversion remain very poorly understood.The present study aimed at evaluating effects land use change for a region on volcanic soils Veracruz, Mexico.For this, micrometeorological, ecophysiological measurements combined stable isotope data were used.The findings showed higher annual yields pasture, as well young mature Pinus patula pine plantations due to lower evapotranspiration rates compared secondary forests.Total seasonal found similar both forests, suggesting catchment functioning can be restored within 20 years natural regeneration.Conversely, pasture streamflow (10 %), however 50 % average baseflow end dry season, more gentle slopes combination soil infiltration capacity.Further, it was shown that promote major increases overland flow response maximum rainfall events, despite high permeability characterizing this environment.The ultimate effect P. reforestation scale still unknown, though rates, suggest recovery short medium term.
