The Sultanate of Oman, like other oil producing countries in the Middle East, is developing at a very fast rate. Asphalt roads, housing and other amenities are being built to fulfil the needs of a growing nation. There are as yet no documented threats to the flora. However, environmental pressures such as overgrazing due to increased livestock holdings and development projects make it imperative that a plant list is compiled presenting the known status of the flora to identify the endemic, regional endemic, rare and threatened species and their areas of distribution. The object of making such a list is not only to provide ready information on the status of a particular plant species, but also to provide information on regions of high endemism, areas with rare species and species of special biological interest. This information is indispensable to the formation and management of nature reserves and the formulation of conservation strategies. Data on the distribution pattern of species is vital for any development plans in the country and successful monitoring of species at risk.
