Contribution of ecological restoration in preservation of forests ecosystems in Algeria

Abstract

Abstract Under the combined effect of anthropogenic pressures and climate change, forest ecosystems can no longer play their ecological and economic role if nothing is done to adapt them. The impacts of fires, overgrazing and overexploitation are that over 60% of forest ecosystems are in an advanced stage of degradation. It is in this context that a new strategy focused on ecological restoration must be quickly put in place. It must be based on ecological alternatives designed to adapt the composition and structure of these plant formations to environmental conditions. The concept of stable species, living space, keystone species, natural attributes and habitat identification. The ecological restoration proposed will allow preserving the vegetal cover at first time and then developing the species with resilience through a list of species that could develop under different pressures, both natural and anthropogenic.
