Oman is home to a mixture of plants and animals. Grasses, shrubs, and hardy trees such as the acacia grow naturally. Grapes and apricots are grown on the slopes of Al Jabal al Akh?ar. Coconut palms grow on the south side of the mountains in Dhofar and frankincense trees on the north. There are no truly fertile agricultural soils; the best are the alluvial soils washed down from the mountains, both in the interior and along the coast. Some of the valuableest fishing grounds in the world are off the coast of Oman, with tuna and sardines among the principal catches. Goats, sheep, camels, and some cattle are raised. Wildlife includes several hundred species of birds, lizards, snakes, and scorpions.
