Abstract: Field surveys of the plants and vegetation of the Mujib Biosphere Reserve in Jordan were carried out between 2005 and 2007. The study covered all areas of the reserve as defined by latitudes 7425000 W to 757000 E and longitudes 3501000 N to 3474500 S (total reserve area = 220 km2). Plants and their veg-etation were sampled both by area plots and line transects. Transect routes were directed from east to west across the reserve and defined as sectors (1-7). These generally included a range of altitudes from 900m down to -400m along the border with the Dead Sea. Various parameters were recorded dur-ing the study including the site name, its location (GPS coordinates), princi-ple plant species present, and their life forms together with associated spe-cies and soil conditions. Various species were collected, photographed, and later deposited at the Herbarium of the Department of Biological Sciences, Faculty of Science, University of Jordan. From the various plant associations observed, three biogeographic regions were recognised, namely Mediterra-nean, Irano-Turanian and Tropical (Sudanian). In addition, five plant commu-nities were identified and allocated to named classes as Artemisia herba-alba; Retama raetam – Salsola vermiculata; Zygophyllum dumosum; hydric vegetation and tropical vegetation. Differences within classes were grouped as sub-classes. The total number of plant species recorded during the survey was 408 which in-cluded several new and rare species to the flora of Jordan. An illustrated map showing the distribution of vegetation areas across the reserve is presented.
