    Inventory of the southern Cedar forest of Bordj-Bou-Arreridj province Floristic biodiversity –Ethnobotany –Conservation

    To preserve the plant community in the face of degradation and environmental changes like drought and human pressure at Djebel Maadid, a relic steppe environment in the Atlas cedar (Cedrus atlantica) formation in northern Algeria, it is crucial to inventory and assess the existing flora. This will help diagnose the current ecological state of the area and inform conservation strategies for this natural heritage. A systematic subjective non-probability sampling was conducted in 73 surveys, identifying 174 species across 91 genera and 39 botanical families. The Mediterranean region is the dominant chorological origin, and the most common life-form is Therophyte (45%). Numerical analyses using Similarity index and Detrended Correspondence Analysis (DCA) revealed two groups of plant samples with distinct environmental states related to temperature, humidity, altitude, and site characteristics. Species richness concentrated in specific vegetation surveys may play a significant local role in the in-situ conservation of plants and habitats. These areas of high species diversity should be prioritized for urgent conservation action. Desertification, land degradation, and drought caused by human activities and climatic variations are a silent crisis affecting people and the planet. Halting degradation and rehabilitating degraded land through restoration will be key to enhancing biodiversity, restoring ecosystem services, and mitigating climate change impacts. Technological solutions based on scientific innovations and indigenous knowledge, such as crop diversification, drought-resilient plants, reduced tillage, improved irrigation, and moisture conservation methods, can help reduce soil degradation and increase agricultural resilience to climate change. Protecting the Atlas cedar formation and the associated plant community at Djebel Maadid is crucial for preserving biodiversity, ecosystem services, and the rights of local communities who depend on these lands. A human rights-based approach and dedicated resources are needed to implement the Convention to combat desertification and achieve the ambitious goals of land restoration.
