Sustainable management of Zarrinabad forest using fuzzy planning and modeling to generate alternative approach

In this paper, Zarrinabad forest management is examined with attention to economic effects of wood harvested according to the environmental goals with different levels of ecological. Environmental objectives include significant increase in deadwood, increasing the area of broad-leaved forest and old forest area. This analysis is performed using fuzzy linear programming that predicts net present value of wood production with respect to the defined constraints and crates various management programs for successive years through MGA method. This program act such that different environmental goals such as increasing areas of broad leaf forests, age of forests as well as  economic goals including  net worth maximizing can be achieved at the end of  programming horizon. Data such as old forest area, forest type, forest age and other information related to the third ten-year project study of this area forestry was provided from the Department of natural resources of the Sari city, and fixed and variable costs of timber harvesting and reforestation was collected from Neka-Choob Company. Results showed that net present value decreases after implementing environmental objectives.
