Ziziphus spina-christi, also known as Christ's thorn or nabk, is a deciduous shrub or small tree native to the Middle East and Africa. In Qatar, it is commonly found in wadi beds, rocky areas, and desert landscapes. Studies have reported its presence in various regions of Qatar, including the Al Reem Biosphere Reserve and other protected areas. The plant is adapted to the arid environment, with a deep root system allowing it to survive drought conditions. In Qatar, Ziziphus spina-christi has been found to play an important role in stabilizing soil and providing habitat for local wildlife, such as birds and insects. Its fruit is also a food source for many animals, highlighting the plant's ecological significance in the Qatari ecosystem.
