| Abstract | The effect of Pinus radiata (D. Don) plantations on water resources at some Chilean sites having different edapho-climatic characteristics was determined. The different components of the water balance were measured at each site where the Pinus radiata plantations were 12 to 17 years old and between 700 and 830 trees ha -1 dense. The results were compared with those obtained from areas covered with perennial grasses and shrubs at the same sites. Annual interception losses (as a percentage of incoming precipitation) increased from south to north (from 15 to 40%). The same occurred with annual net evapotranspiration, which was 32% of incoming precipitation for the southernmost site and 55% for the one located in the lower latitude. Annual percolation registered its minimum value in the northern site (5% of incoming precipitation) and its maxima in the southern one (53%). Compared with the shrub or grass covers, sites under Pinus radiata plantations registered higher water consumption by evapotranspiration and reduced percolation. |
