Abstract : The present study classifies medicinal plants in the flora of Jazan region according to species threatened into rare, vulnerable, endangered, critically endangered and extinct. It focuses on the reasons of species decline as habitat loss (agriculture, harvesting practices, over-grazing, urban development, shore activities and tourist torsion), introduction of exotic species, diseases, pollution and drought. The solutions for conservation of species including preservation, restoration, examination, documentation, research, advising, treatment, training and education are discussed. The information provided in this study points to the need for broader monitoring for existing species and continuous conservation research should be given top priority.
