The main ethnico-linguistic groups are the Daza (55.96%), the Teda (22.63%), the Zaghawa (10.17%) and the Arabs (2.57%).
There is a variety of fauna and flora in this region. Previously the Chadian wild dog (Lycaon pictus sharicus) had populations in this region, but they are now regarded as extirpated from the area,[2] due to activities of humans as well as desertification, a phenomenon associated with the expanding human population.
