Abstract
This study was conducted at Sabratha National Park, in Sabratha, 70 km westwards Tripoli, between the two points N 32° 48' 54" – E 12° 22' 48" and N 32° 48' 54" E 12° 23' 06" in the north, and the two points E12° 23' 42" – N 32° 48' 00" and E 12° 24' 00" – N 32° 48' 00" in the south, on an area estimated at 500 hectares, during the period of May 2014 to May 2015. We reported the presence of six classes inside Sabratha National Park; class Reptilia which included six species: Tarentula mauritanica, Chalcidae ocellatus, Mesalina guttulata, Chamaeleo chameleon,and Naja haje; class Amphibia which included a single species Bufotes boulengeri, class Aves; which included ten species: Burhinus oedicnemus, Streptopelia decaocto, Columba Livia, Streptopelia senegalensis, Athene noctua, Turdoides fulva, Sturnus vulgaris, Passer hispaniolensis, Upupa epops, and Lanius meridionalis; class Mammalia which included two species: Erinaceus algirus and Jaculu jaculus; class Insecta which included eight orders: Orthoptera, Dictyoptera, Diptera, Hymenoptera, Hemiptera, Coleoptera, Odonata, and Lepidoptera; and class Arachnida which included three orders: Araneae, Scorpioida, and Opiliones. There likewise exist some species for the purpose of reproduction and redistributed in native habitat such as Gazelle dorcas, Ory leucoryx and Struthio camelus. With regard to plant diversification, there is plenty of pine trees (Pinus pinea), and Eucalyptus arnaldulensis, and some trees of Casuarina equisetifolia inside the park, in addition to random spread of some shrubs and herbs, some of which are of medicinal importance such as Teucrium polium.
