Diversity and ecological importance of plants in traditional agroforestry of Sudano-sahelian domain of Cameroon: case of Meri in the Mandara Mountains

Sudano-Sahelian domain is the poorest in biodiversity because of climate which unfavourable compared to equatorial climate. The unsustainable agricultural practices associated with this climatic roughness are among main factors habitat destruction, hence destruction phytogeographic environment. In order valorize and conserve sudano-sahelian plant resources, a study was carried out seasonal agrosystems Mandara Mountains. Diversity floristic diversity were assessed. Inventories woody plants done 16 plots (100 m x 100 m) grouped 4 localities/villages. circumference trunk all inventoried (circonference ≥ 10 cm) measured. total, 64 species 45 genera 27 families inventoried. highest FIV obtained for Mimosaceae (FIV = 104.51) Combretaceae 51.22), other had < 30. Diversities localities (Shannon index ranging from 2.82 2.86 bits) lower than whole stand 3.09 bits). Acacia albida (IVI 53.52, RI 6.25), nilotica 9.18, 18.75), seyal 5.19, 43.75), Anogeissus leiocarpus (IVI) 41.82, 0), Balanites aegyptiaca 14.23, 12.50), Diospyros mespiliformis 9.91, 37.50), Tamarindus indica 16.35, 12.5), Ziziphus mauritiana 9.52, 31.25) observed localities. There considered as characteristics represent background stand. Traditional can be tools conservation wild useful local populations. It would imperative situ species, source genetic their sustainable use.
