Geography and nature Sindh is in the western corner of South Asia, bordering the Iranian plateau in the west. Geographically it is the third largest province of Pakistan, stretching about from north to south and (extreme) or (average) from east to west, with an area of of Pakistani territory. Sindh is bounded by the Thar Desert to the east, the Kirthar Mountains to the west and the Arabian Sea and Rann of Kutch to the south. In the centre is a fertile plain along the Indus River. Sindh is divided into three main geographical regions: Siro ("upper country"), aka Upper Sindh, which is above Sehwan; Vicholo ("middle country"), or Middle Sindh, from Sehwan to Hyderabad; and Lāṟu ("sloping, descending country"), or Lower Sindh, mostly consisting of the Indus Delta below Hyderabad. Flora The province is mostly arid with scant vegetation except for the irrigated Indus Valley. The dwarf palm, Acacia Rupestris (kher), and Tecomella undulata (lohirro) trees are typical of the western hill region. In the Indus valley, the Acacia nilotica (babul) (babbur) is the most dominant and occurs in thick forests along the Indus banks. The Azadirachta indica (neem) (nim), Zizyphys vulgaris (bir) (ber), Tamarix orientalis (jujuba lai) and Capparis aphylla (kirir) are among the more common trees. Mango, date palms and the more recently introduced banana, guava, orange and chiku are the typical fruit-bearing trees. The coastal strip and the creeks abound in semi-aquatic and aquatic plants and the inshore Indus delta islands have forests of Avicennia tomentosa (timmer) and Ceriops candolleana (chaunir) trees.
