Biodiversity in West Asia

Indigenous plant and animal life in West Asia is under increasing threat due to the impact of development.Overgrazing and mismanagement of rangelands have led to the loss of natural plant cover. Deforestation is now a major concern in the highlands of Yemen, Oman, and Jordan. Overfishing, pollution, and destruction of habitat (from land reclamation and filling in of wetlands) have all had a negative impact on marine biodiversity. As a result, declining fish and shrimp harvests have become a common feature in the Persian Gulf region.
The depletion of underground water levels on the western side of the Gulf is leading to the loss of a unique ecosystem of natural fresh-water springs, affecting large numbers of plants and animals. This ecosystem was once widely distributed in the eastern province of Saudi Arabia and in Bahrain.The Azraq Oasis in Jordan was declared a wetland under the RAMSAR Convention because it was endangered due to the overextraction of ground water. The overextraction is not only depleting the ground water, it is leading to increased salinity, which in turn negatively affects wildlife and plant species in the area.
In West Asia, wildlife such as fallow deer, ostrich, wild goat, and antelope have been threatened with extinction due to indiscriminate hunting. The threat to wildlife is worsened through the destruction of their habitats, particularly deforestation. The region lost 11 per cent of its remaining natural forest during the 1980s, and natural forest cover now averages less than 1 per cent of the total land area .
On the whole, there is little information on species, and good data are generally limited to certain mammals and birds. Species inventories are currently being undertaken in a number of countries in the region [such as Jordan and some Gulf Cooperation Council (GCC) countries].
