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.
Highlights
The preservation forest ecosystem is an obligation for an arid country like Algeria, which is both ecological and economic
Whatever saying policies, Algerian forests are primarily conservation training that are essential in maintaining biodiversity and ecosystem resilience
The Algerian forests are a source of teaching about the natural evolution of ecological processes animal and plant populations, they validate the approach deployed on the developed territory by serving as a reference
Summary
The preservation forest ecosystem is an obligation for an arid country like Algeria, which is both ecological and economic. Forests in the strict sense represent only 1 million hectares of the 4,300,000 ha where successful reforestation is only 750,000 ha on the 3 million hectares reforested [1]
