Description & Remarks

This is the most common spontaneous species of Acacia in Israel. It constitutes a savannoid landscape in the extreme desert where trees are accompanied by desert shrubs and dwarf shrubs (Fig. 7), and herbaceous Mediterranean plants north of Beer Sheva. Fig. 8 displays a typical landscape in Sinai where the A. raddiana trees occupy wide wadis, whereas the slopes are almost plant-less. The Acacias bloom in Israel according to the climatic rhythm of their origin area. It is assumed to be the Sahel plains in Africa. Often, the water reserves in their large rhizosphere enables blooming with no local rain showers and then they bear minute leaves(Fig. 1).
Most Acacia seeds are punctured by seed-beetles who consume their content. According to studies of Gideon Halevy and his colleagues, conducted in Israel and Africa, seeds that passed the intestinal tracks of goats, gazelles, ibex, hyrax may germinate. While in the intestinal system, the beetles may die and the surviving seeds may germinate if the year is rainy.
