Zarqa River
Archaeological finds of charcoaled remains indicate that poplar and tamarix used to grow along the banks of the Zarqa, with forests of wild oak growing on the hillsides. Today, tamarix thickets are still widespread in the floodplains, and the banks are cultivated with fruit orchards and vegetable fields. Along the course of Zarqa River, water is pumped directly and used to irrigate crops of leafy vegetables such as parsley, spinach, cabbage, cauliflower and lettuce, as well as potatoes. Olive trees are also found along the river's banks. Tulips grow on many hillsides of the river, while in the springs area and the watercourse, water vegetation is found. Natural pine forests grow in the King Talal Dam area. Along the upstream banks, where the river runs wild, one finds the common reed, oleander and Typha species.
