This study is aimed to investigate the general range status, adequacy and availability. In the study, identification of the dominant palatable plant species which are existence, estimation and assessment of the carrying capacity of the rangeland. The study was conducted in two phases: a general survey to collect observations all over the state (six localities), and sampling the Rosaries locality for the carrying capacity in a randomized samples and quadrate method. In the results, 50 plants species were described and the carrying capacity was estimated using national and international equations. The area is predominantly covered by average vegetation density, this density increases from north to south and from the west (Eastern River bank) to East. The predominant forage plant species were: Pennisetum ramsum “keereja,danab albaashum”, Borreria radiate “smsm aljedad”, Ischaemum afrum “Ancouj”, Rhynchosia minima var. memnonia “adan elfar”, Brachiaria lata “zebrtaia”. And the main predominant trees species were Acacia seyal var seyal “Talih ahmer”, Balanites aegyptica “higlig”, Acacia seyal var fistula “Talih abide”, Compratum hartimannianum / polyacantha “habil”, Acacia seriana “kakamout”. A proximately 40% of the soil is bare while 60% is covered with vegetation. The usable plant material is 0.68 ton/ha and the carrying capacity is 0.451AU/per season by using Proper Usage Factor (PUF) 40%, or 0.68 ton/ha and the carrying capacity is 0.57 per season by using PUF 50%. The most dominant six species in terms of frequency include Pennisetum ramsum “keereja,danab albaashum” 54%, Borreria radiate “smsm aljedad” 42%, Ischaemum afrum “Ancouj” 41%, Rhynchosia meinina var. memnonia “adan elfar 28%, Brachiaria lata “zebrtaia” 18.6%, Minima spp “draeia, Alagaiz gelsen” 15.3%. In the study area, results showed that the density of the six dominant species are 10, 6, 1, 1, 1, plant per square meter for Pennisetum ramsaum, Borreria radiate, Ischaemum afrum, Aristida mutabils, Cymbobogon spp, and Rhynchosia memnonia. These six dominant species include four (4) less desirable species and only two (2) desirable species and no undesirable species were recorded. All this indicates that the general status of studied rang land is good according to the main quantitative measurements, but, in the same time it’s in a continuously decline comparing with the past studies. The study recommends were re-opening and re-habitat the graze routs with cooperation between the related sectors. The study recommended to reopen and re-habitat the nomad roads, increase the water points and the legumes species, use machines to harvest green fodders to cover part of the stock needs in the summer, initiate seed bank and Integration between all related sections to the land.
