Skidding Routes Simulation for Opening Access to High-Risk Fire Areas

Physical barriers such as roads cause to decrease fire distribution through reducing fire speed and increasing accessibility to affected area and control fire. In this research it is necessary to (i) predict forest fire risk zones and (ii) simulation skidding routes in order to access of fire controller teams to risk zones. For this propuse, skidding routes was simulated through FORENG 1.0 software. The simulation results showed that the skidding routes with same length in gentle slopes have more coverage as compared to steep slopes. So that, was found significant diffrence between treatments (P < %5). Moreover, by reducing the straight length of v skidding routes the overlapped area increased because of their spiral shape. So the coverage area decreased. Skidding routes had significant effect on covering natural fire risk areas (P < %5). About 58.5% of areas in the v category of moderate fire risk and 48.6% of areas in the category of high fire risk are covered by this network. In order to prevent and control fire, the management team of tension must be created. Also, the fire risk zone map can be a guideline for providing fire controller and prevention of fire during the planning of forest road and skidding routes.
