The
total length of Hyrcanian forest roads in Iran at the end of
year 2009 was about 10000 km. Forest roads facilitate timber
harvest and attainment of other multiple use objectives
requires a high capital investment. A mistake in planning a
road, such as ignoring the effects of environmental and
other parameters leads not only to the waste of public
investment but also to adverse environmental impacts and
increase maintenance costs. In Iranian forestry system, road
planning and building process can be partitioned into
network planning, transferring network from the plan to the
ground, mapping, data processing and sections design,
right-of-way felling, pioneering, right-of-way logging,
clearing and grubbing, excavation and embankment, subgrade
finishing and surfacing. Nowadays the GIS techniques have
been suggested to design the optimal forest road density in
northern forest of Iran. The GIS and computerized analyzing
by AutoCAD and RoadEng softwares helps to economize time,
costs and to minimize environmental damages.
