The forest of the hight Mount Lebanon massif, at altitudes between 1400 and 3086 meters, holds the largest forest extent in Lebanon. However, under the pressure of meeting local residents' needs, the forest gradually lost its density, causing the disappearance of this landscape. Deforestation has exposed fragile slopes to water erosion. The effects of deforestation have the direct impact of exposing fragile slopes to water erosion. The combination of aerial photographs and multi-date satellite images allows for a diachronic analysis of the forest landscape as well as a synthetic description of the organization and spatial distribution of these tree formations. Interpreting the results, that should account for the interaction between people and their environment, revealed a decline in the forest area between the years 1962-1984, while an increase is marked in the two periods 1984-2000 and 2000-2018.
