Ostriches were imported from Chad and reintroduced to Souss-Massa National Park in Morocco. In Tunisia, North African ostriches were once common in the southern region of the country. The subspecies had been extirpated since 1887. In 2014, North African ostriches were finally returned to Tunisia after 127 years of being extinct. The birds were first reintroduced to Dghoumès National Park. They were then reintroduced to Sidi Toui National Park, and then to Orbata Faunal Reserve.

North African climate cycles of a vegetation-insolation threshold, which if reached, allows the Sahara region to rapidly transition from "green Sahara" to "desert Sahara" and vice versa. North African climate cycles North African climate cycles have a unique history that can be traced back millions of years. The cyclic climate pattern of the Sahara is characterized by significant shifts in the strength of the North African Monsoon. When the North African Monsoon is at its strongest, annual precipitation and consequently vegetation in the Sahara region increase, resulting in conditions commonly referred to as the "green Sahara". For a relatively weak North African Monsoon, the
