A Review of Existing Forest Network and Planning of Most Appropriate Forest Road Network with Regarding to Silvicultural Objectives in Series 1 of Makarood Forest Management Plan

In case of to the high costs of road construction at forest; it is necessary to create a road network which cover more area with low length and least destruction. This research for planning the best network by considering the silviculture aims, used the topographic map, slope map, hydrographic, geology, soil, land stability, silviculture condition and..., but because of low density and inaccessibility to some high quality forest area, it could not respond to the expected aims, therefore taking cate of all effective factors, the predicted main roads network which ratified by forests organization and proposed network which suggested by this research were assessed and considered. The access roads included both networks ,the characteristics of the predicted network and proposed network respectively are: length 45.448 & 42.840 Km, length density 16.64 & 15.68 m/ha , network cover 65.36% & 69.73%, by comparison of two network and identify high lighted main points such as density, cover percent, slope, percent of the roads which pass of the stable area and other factors, the proposed network by this research selected and suggested because of less density, high percent of network cover, better communication and passing of more stable area, reduction of secondary paths, decrease the costs of wood harvesting, transportations, road construct and maintenance, technical structures.
