In spite of the lack of precipitation, the natural vegetation of Egypt is varied. Much of the Western Desert is totally devoid of any kind of plant life, but where some form of water exists the usual desert growth of perennials and grasses is found; the coastal strip has a rich plant life in spring. The Eastern Desert receives sparse rainfall, but it supports a varied vegetation that includes tamarisk, acacia, and markh (a leafless, thornless tree with bare branches and slender twigs), as well as a great variety of thorny shrubs, small succulents, and aromatic herbs. This growth is even more striking in the wadis of the Red Sea Hills and of the Sinai and in the ʿIlbah (Elba) Mountains in the southeast.

The Nile and irrigation canals and ditches support many varieties of water plants; the lotus of antiquity is to be found in drainage channels in the delta. There are more than 100 kinds of grasses, among them bamboo and esparto (ḥalfāʾ), a coarse, long grass growing near water. Robust perennial reeds such as the Spanish reed and the common reed are widely distributed in Lower Egypt, but the papyrus, cultivated in antiquity, is now found only in botanical gardens.

The date palm, both cultivated and subspontaneous, is found throughout the delta, in the Nile valley, and in the oases. The doum palm (Hyphaene thebaica; an African fan palm) is identified particularly with Upper Egypt (the southern part of the Nile valley) and the oases, although there are scattered examples elsewhere.

There are very few native trees. The Phoenician juniper is the only native conifer, although there are several cultivated conifer species. The acacia is widely distributed, as are eucalyptus and sycamore. Several species of the genus Casuarina (beefwood order), imported in the 19th century, are now the country’s most important timber trees. Other foreign importations, such as jacaranda, royal poinciana (a tree with orange or scarlet flowers), and lebbek (Albizia lebbek; a leguminous tree), have become a characteristic feature of the Egyptian landscape.

Domestic animals include buffalo, camels, donkeys, sheep, and goats, the last of which are particularly noticeable in the Egyptian countryside. The animals that figure so prominently on the ancient Egyptian friezes—hippopotamuses, giraffes, and ostriches—no longer exist in Egypt; crocodiles are found only south of the Aswān High Dam. The largest wild animal is the aoudad (a type of bearded sheep), which survives in the southern fastnesses of the Western Desert. Other desert animals are the Dorcas gazelle, the fennec (a small, desert-dwelling fox), the Nubian ibex, the Egyptian hare, and two kinds of jerboa (a mouselike rodent with long hind legs for jumping). The Egyptian jackal (Canis lupaster) still exists, and the hyrax is found in the Sinai mountains. There are two carnivorous mammals: the Caffre cat, a small feline predator, and the ichneumon, or Egyptian mongoose. Several varieties of lizard are found, including the large monitor. Poisonous snakes include more than one species of viper; the speckled snake is found throughout the Nile valley and the Egyptian cobra (Naje haje) in agricultural areas. Scorpions are common in desert regions. There are numerous species of rodents. Many varieties of insects are to be found, including the locust.

Egypt is rich in birdlife. Many birds pass through in large numbers on their spring and autumn migrations; in all, there are more than 200 migrating types to be seen, as well as more than 150 resident birds. The hooded crow is a familiar resident, and the black kite is characteristic along the Nile valley and in Al-Fayyūm. Among the birds of prey are the lanner falcon and the kestrel. Lammergeiers and golden eagles live in the Eastern Desert and the Sinai Peninsula. The sacred ibis (a long-billed wading bird associated with ancient Egypt) is no longer found, but the great white egret and cattle egret appear in the Nile valley and Al-Fayyūm, as does the hoopoe (a bird with an erectile fanlike crest). Resident desert birds are a distinct category, numbering about 24 kinds.

The Nile contains about 190 varieties of fish, the most common being bulṭī (Tilapia nilotica; a coarse-scaled, spiny-finned fish) and the Nile perch. The lakes on the delta coast contain mainly būrī (gray mullet). Lake Qārūn in Al-Fayyūm governorate (muḥāfaẓah) has been stocked with būrī and Lake Nasser with bulṭī, which grow very large in its waters.
