Botanical Explorations in the Middle East started almost 800 years ago Ibn al-bayṭār (1197-1248) was a Muslim scientist, botanist, pharmacist and physician. Born in the Andalusia in Malaga, he learned botany from the Málagan botanist Abu al-abbas al-nabati with whom he started collecting plants in and around Spain. In 1219, Ibn al-baytar left Málaga to travel in the Islamic world to collect plants. He travelled from the northern coast of Africa as far as Anatolia, and in 1224 went to Damascus and collected plants in Syria, Arabia and Palestine. Collection of Simple Drugs and Food, an encyclopaedia of about 1500 medicinal substances that he collected over his lifetime. Peter Forsskål (Pehr Forsskål) (11 Jan 1732-11 July 1763) was a Swedish explorer, naturalist and an apostle of Carl Linnaeus. Collected in Lower Egypt, Sinai, Palestine. Collections in C, where many of his plants were lost to bad storage herbarium resurrected by Carl Christensen some 150 year later. The entire journey of this Danish expedition was written by Thorkild Hansen Det lykkelige Arabien (1962, translated into English as Arabia Felix). Flora Ægyptiaco-Arabica sive descriptiones plantarum quas per Ægyptum Inferiorem et Arabiam felicem detexit, illustravit Petrus Forskål - plants of Yemen and of lower Egypt (1775)

His book Relations de Voyages en Orient de 1830 à 1838 was published posthumously in 1843. Wilhelm Peter Eduard Simon Rüppell (1794-1884) German naturalist and explorer. Rüppell is occasionally transliterated to "Rueppell" for the English alphabet. Visited Sinai in 1817; first expedition in 1821, with surgeon Michael Hey as his assistant - through the Sinai desert; in 1822 both were the first European explorers to reach the Gulf of Aqaba; went to Mt Sinai, Nile, Sudan, Ethiopia.

Biogeography Palaearctic (left) and Afrotropic (right) ecozones. At a global scale, the Middle East is lies in the transition zone between two major biogeographic units, the Palaearctic and Afrotropical Ecoregions. The Arabian Desert separates the Palearctic and Afrotropic ecozones, and forms a transition zone between the Afrotropic and Mediterranean basin to the north. (WWF Ecoregions. Olsen et al. 2001.)
Biogeography The southern Arabian woodlands found mostly in south western parts of the Arabian Peninsula (mostly Yemen, parts of western Oman and southwestern Saudi Arabia) have a few permanent and seasonal forests with elements of East African and Ethiopian floras. Other woodlands scatter the land and are very small and are predominately juniper or acacia woodlands (WWF Ecoregions. Olsen et al. 2001.)
Biogeography Palaearctic and Afrotropic ecozones. The Mediterranean Basin (of the Palaearctic ecoregion has about 13,000 endemic species. Designated as one of the world's biodiversity hotspots. The Iranian plateau is home to dry, steppe grasslands and desert basins, with montane forests, woodlands, and grasslands in the region's high mountains. (WWF Ecoregions. Olsen et al. 2001.)
White s definition of floristic regions for Africa: 50% of species confined to that region; 1000 endemic spp. found in the same phytochorion. Leonard defined the floristic regions of the Middle East. Phytogeography of the Middle East M The Mediterranean region, occupies a narrow belt along the Mediterranean Sea, with a gap between Palestine and Libya where the desert closely approaches the Mediterranean SS the Saharo-Sindian region occupies Egypt, Sinai, most of the Arabian Peninsula, southern Palestine, Jordan and Israel and SE Iraq J. Leonard (1988, 1989) IT the Irano-Turanian region occupies about half of the Middle East, mainly C and E Turkey, Iran, Iraq, Syria, Israel, Jordan and Palestine; it is floristically rich and high in endemism and a centre of radiation of several genera

J. Leonard (1988, 1989)
Mediterranean regional centre of endemism (M): Occupies most of western Jordan, the mountains and Jordan valley. Representative vegetation: coniferous forests of Aleppo pine (Pinus halepensis) and Callabrian pine (Pinus brutia not in Jordan); and dry oak (Quercus spp.) woodlands and steppe formations. Olive (Olea europea), carob (Cerotonia siliqua), oak (Quercus coccifera most widespread), pistachio (Pistacia palestina, P. lentiscus), and Arbutus andrachne are the principal species. In addition Phillyrea latifolia, Pistacia terebinthus, Calicotome villosa, Genista acantha, Rhamnus oleoides, Myrtus communis, Laurus nobilis, Styrax officinalis, and Spartium junceum also occur. Vegetation is degraded, in particular Ceratonia siliqua that it is only represented by a few individuals.

It increases in frequency and spreads following overgrazing, and its relative dominance is used as an indicator of poor rangeland management and land degradation.
