Plants are those common in dry subtropical and tropical lands, such as papyrus. Egypt has no forests but does have date palm and citrus groves; eucalyptus and cypress have been introduced. Sheep, goats, and donkeys are found throughout the country, and camels are found in all the deserts. Egypt has some 300 types of birds, with about half of them being breeding species within the country. Wild animals are few, except for the hyena, jackal, lynx, mongoose, and wild boar, the last-named inhabiting the Nile Delta. The ibex may be found in the Sinai, and gazelles in the deserts. The Nile is adequately stocked with fish, but crocodiles have been reduced to a few along the shores of Lake Nasser. Reptiles include the horned viper and the hooded snake.
