Qattara Depression - Ecology

Ecology

Groves of Acacia raddiana, growing in shallow sandy depressions, and Phragmites swamps represent the only permanent vegetation. The Acacia groves vary widely in biodiversity and rely on runoff from rainfall and groundwater to survive. The Moghra oasis in the northeast of the Depression has a 4 kmĀ² brackish lake and a Phragmites swamp.

The south western corner of the depression is part of the Siwa Protected Area which protects the wild oasis in and around the Siwa Oasis.

The Depression is an important habitat for the cheetah, with the largest number of recent sightings being in areas in the northern, western and northwestern part of the Qattara Depression, including the highly isolated, wild oases of Ain EI Qattara and Ein EI Ghazzalat and numerous Acacia groves both inside and outside the depression.

Gazelles (Gazella dorcas and Gazella leptoceros) also inhabit the Qattara Depression, being an important food source for the cheetah. The largest gazelle population exists in the southwestern part of the Qattara Depression within a vast area of wetlands and soft sand. The area of 900 square kilometres (350 sq mi), includes the wild oases of Hatiyat Tabaghbagh and Hatiyat Umm Kitabain, and is a mosaic of lakes, salt marshes, scrubland, wild palm groves and Desmostachya bipinnata grassland.

Other common fauna include the Cape Hare (Lepus capensis), Egyptian Jackal (Canis aureus hupstar), Sand Fox (Vulpes rueppelli) and more rarely the Fennec Fox (Vulpes zerda). Barbary sheep (Ammotragus lervia) were once common throughout but now are few in numbers.

Extinct species from the area include the Scimitar Oryx (Oryx dammah), Addax (Addax nasomaculatus) and Bubal Hartebeest (Alcelaphus buselaphus). Also the Droseridites baculatus, an extinct pollen, was found at the Ghazalat-1 Well.
