has a dry Mediterranean to Saharan climate. It comprises from North
to South: the Jaffarah Plain; the Jabal Nafusah bordered by a high scarp
(Average 600 m elevation), a gently south dipping plateau; the desert
including large wadis and basins in the areas of Mizdah and Bani Whalid
and southwards, the monotonous Hamada al Hamra. In the West of the Hamada
al Hamra, close to the borders of Algeria and Tunisia are the oases
of Derj and Ghadamis.
The Jaffarah Plain is dominated in the north by irrigated agriculture and by pastoralism. It gets dryer south close to the Jabal Nafusah. Natural habitats are most often sandy (vegetated dunes) and rocky along the wadis and the coast. A dry Mediterranean to sub-desertic vegetation is encountered with a “green” season for the annual plants from winter to mid-April.
The coast is characterised by closely related habitats and saline environments with large sabkhas between Sabratah and Tunisia and along the Gulf of Sirt.
Jabal Nafusah is mostly dry (steppe) and rocky, with
more bushes and vegetation in the wadis, which are often cultivated.
Habitats get greener and richer from west to east. Southward nice wild
or cultivated wadis are found (Mizdah, Bani Whalid area) and the monotonous
Hamada al Hamra which stretches towards Fazzan. Habitats
in the Hamada correspond to wadis and temporary ponds (dhayas).
To the West are the oases of Ghadamis and Derj with their gardens and
