Desert hyacinths grow in the "sabkha" plains east of the city, while acacia and ghaf trees grow in the flat plains within the proximity of the Western Al Hajar mountains. Several indigenous trees such as the date palm and neem as well as imported trees such as the eucalyptus grow in Dubai's natural parks. The houbara bustard, striped hyena, caracal, desert fox, falcon and Arabian oryx are common in Dubai's desert. Dubai is on the migration path between Europe, Asia and Africa, and more than 320 migratory bird species pass through the emirate in spring and autumn.
