Abstract: | Rural development in forested lands and high altitude ecosystems created new regimes and disturbances that set protective function of forests as the most fundamental of all forest functions. Considering protective forests as engineering structures against natural hazards and risks, such as erosion, able to replace costly manmade infrastructures, a methodology is presenting aiming at their spatial identification in a changing mountainous environment. The methodology followed is based on field observations, calibrated models, topographical, geological and climatic data as well as human presence indicators combined properly in a GIS environment. Analysis showed that some forest soils are prone to erosion hazard unable to absorb disturbances like selective logging, revealing the protective role of their forest cover. The spatial identification of the forests with a particular protective function is the necessary step required for the design of a sustainable management of high elevated ecosystems. |
