Jabal Qaraqir in Saudi Arabia is the first site to be assessed for the Important Plant Area (IPA) programme in the Arabian Peninsula. This paper describes the geology, fauna and flora of the Qaraqir site and provides the first botanical checklist of the area. It designates the locality as an IPA due to the quality of the wadi vegetation and the presence of endemic and biogeographically relictual species. As well as assessments, this study also touches on the planning stage of conservation activity. Socio-economic issues and threats to the conservation of Qaraqir are discussed and suggestions for conservation action are provided.
