    (Napata College, 2024-04) Reem A. Hamid; Alawia A. Elawad; Elfatih E. Mahgoub
    The present study is the pioneer that document the biodiversity of the Eastern Nile Locality, Khartoum State, Sudan including five range enclosures. The main objective of the present study is to document the natural vegetation status and floristic, faunal composition in five rangeland enclosures namely Abozaid (15° 46′ 928″, 32°88′549″) Wadtbar (15° 42′ 846″,33°06′552″), Elhedabab (15° 42′ 893″, 33°002′ 36″), Salamat Wad Niel (15° 652′ 680″, 33°25′ 928″) and Seyal Elfaki Saad (15° 54′ 976″, 33°20′ 724″) in Eastern Nile Locality, Khartoum State, and to provide a recent species list. The quantitative assessment of the flora in the five enclosures was determined by measurement of density, abundance, frequency, relative density, relative abundance, relative frequency and importance value index. On each of the five enclosures 9 plots were selected and the measurements were taken for 3 consecutive years. Nineteen plants were encountered during the survey. The results revealed that the herbaceous cover is dominated by Aristida adscensionis in four of the five studied enclosures while in Elhedabab enclosure Schoenefeldia gracilis is the most dominant species. Standard collection and identification methods were used for both plants and animals. During the study period, a total of 33 plant species, representing 27 genera from 14 families, in 11 orders were recorded. Poaceae had the highest contribution; followed by Fabaceae and Zygophyllaceae. The flora comprises a variety of life-forms; most are theophytes. The majority of the plant species have important ethnobotanical uses. From the collected plant 24 species are fodders grazed or browsed by wild animals and domestic livestock and 24 species are used for medicinal purposes. Almost all plant parts are economically used. The wild faunal survey results indicated the presence of 16 species two of which are reptiles, belonging to 1order falling within 2 families. The avifauna consisted of nine species, falling in seven families within 4 orders. While the observed mammals were 5 species, falling in 5 families. Owing to the results produced by the present study, which represents the base for further ecological studies, there is an urgent need for monitoring and conserving the biodiversity in the Eastern Nile Locality.
