Abstract

Forests are one of the most valuable terrestrial ecosystems that provide variable goods and services. One of the most important functions of forest ecosystems is conservation of water resources and volume of surface runoff water in watershed. In order to determine the value of this function, forest contribution in surface water runoff control and increases of saved water, should be valued by using ECONOMIC VALUATION methods of ecosystem services. In this study in part of CASPIAN FORESTs, height and volume of surface runoff in the current status of the study area (natural forest) was computed with using JUSTIN EXPERIMENTAL METHODs, then by definition of two scenarios including converting the forest area into degraded forest, and converting area to eroded pasture, amount of saved water were computed in each area of defined scenario. Volume of this function was calculated by using SUBSTITUTE COST METHOD. Research results indicate that converting the study area into degraded forest will double the amount of runoff water, and into eroded pasture this volume of surface water will increase more than six times, which means reduction in amount of water stored in underground water table. The value of this forest ecosystem function has been estimated by using substitute costs method. The results show that each hectare of the study area has a value as 102 Thousand Rials ($ 100) by the conservation of water resources, compared with a degraded forest, and 464 thousand Rials ($ 450) compared with an eroded pasture.
