Jbil is the largest National Park in Tunisia. It is situated nearly 100 km south of the town of Kebili. It is an area of the Sahara comprising part of the Great Eastern Erg and a 200-m-high hill. The vegetation is typically Saharan and includes species such as Rhanterium suavolens, Arthrophytum schmittianum, Aristida pungens, Retama raetam, Calligonum arich and C. azel.
See Box and Table 2 for key species. This is only IBA in Tunisia from where Passer simplex has been recorded and one of only two at which Ramphocoris clotbey occurs. In addition, Jbil holds a breeding population of Chlamydotis undulata, very rare in Tunisia.
Non-bird biodiversity: The mammals Gazella dorcas (VU) and G. leptoceros (EN) both occur, but Acinonyx jubatus (VU) probably no longer does so.
Pressure/threats to key biodiversity
Jbil was created a National Park in 1994. Poaching (of gazelles Gazella, sandgrouse Pterocles and Chlamydotis undulata) is the main threat affecting the site.
