Zoning: a tool for the management of mountain protection forest against natural hazards

Abstract

Forests can play a very significant role in the protection against natural hazards and risks in mountain lands, especially against erosion and rockfalls. This paper first assesses the knowledge concerning the forest ability to control natural hazards. Zoning aspects are then presented; based on a GIS use, they allow determining priorities for forest operations, with the view to set up a "minimal management" of mountain forest ecosystems. Finally, it is explained how the results of research are used for management and planning of the mountain ecosystems.
