Wadi is Arabic for valley, generally referring to a valley with flowing water in rainy years. Wadis with flowing water are ideal habitats for oleander, cattail, reed, and other plants that require constant water. They are breeding grounds for amphibians, fish, and insects such as dragonflies and horseflies. Wadis also attract larger animals, including carnivores and migrant birds.
Most wadis with flowing water intersect Jordan’s highlands and terminate in the Jordan Valley. Examples are Wadi Mujib, Wadi Hasa, and Wadi Zarqa. Examples around Amman are Wadi al-Seer and Wadi Shita.
