Djebel Bou Ramli
It is located 25 km north-west of Gafsa, with a peak in 1156m. It consists of limestone and is bounded to the north by alfa steppes, and south by sebkhats. Alfa covers the entire mountain, in association with juniper degraded stands Phoenicia and evergreen oak at the top. The sagebrush country and rosemary are associated with alfa on the lower slopes. A wide variety of species, some of which are rare, is part of floristic Jebel Bouramli.
The fauna is rich enough, but low plant cover limits the extension of large mammals in the region.
Djebel Bou Hedma
Erected in National Park since 1980. It is located 85 km east of Gafsa and 45 km west of the coast. The clumps are carbonated with marl and gypsum. The mountain is surrounded by steppes. The top of Bouhedma has an upper arid bioclimate linked to moisture provided by low clouds
The physical and bioclimatic characteristics Bouhedma are such that they give it a typical vegetation. Downstairs are the pseudo-wooded savannas Acacia radiana or their degradation formations and from the mid-slopes natural vegetation consists of Aleppo pine typical training and their training surout degradation.
The mammalian Region are composed of Dorcas gazelle, jackal, the genet, hare, porcupine, and several species of bats.

The mountains of Matmata
This chain of highlands and low mountains is located along the eastern edge of the Grand Erg. The rainfall varies from 300 mm to less than 200 mm, which is significant in relation to media. The temperatures are milder there.
The plant associations of the north of this chain are degraded scrubland Phoenician juniper. Those in the southern part are different poorest and most degraded. Juniper is scattered upon the mountains and in danger of disappearing. The carob tree, oleaster, mastic, and the Periploca Calycotome also sparse. Common species comprises rosemary, globular, cistus and thyme. The south side door indicator species most degraded environments such as sagebrush and alfa.
The fauna includes several species of rodents, including goundi various raptors and some species of carnivorous mammals (jackal, fox ...). Matmata Mountains form a natural barrier between the desert steppes and the large Erg Oriental, which continues in Libya.
