theirwere Six water bodies in El marsa and Ben Azzouz which are barely observable, in

From the maps, we observe that there were changes in Forest coverage. In 1990, it was
important in the coastal and few other municipalities and it rose in 2000. In 2010, we observe
a decrease in Forests and kept decreasing to 2020. The maps shows that the majority of Skikda

bodies, bare lands and forests.
