Theme 2: Forage--Oral Sessions

Description

The study was conducted in AL Elsabaloga area in Sudan in 2017. This study aimed to assess environmental and biotic factor effects on rangeland plant diversity in the study area. A total sample size of 130 was chosen randomly to collect primary data. The data were coded, summarized, tabulated and processed. Analysis was conducted using (SPSS) computer program. The results were presented in the form of a frequency distribution. There were many problem effects on Rangeland plant diversity. Among these were floods (P < 0.01), expansion of agriculture (P < 0.01), over grazing (P < 0.01), drought, sand marching and desertification (P < 0.01), insect (P < 0.01). In addition, disappear of some plant and appear invader plant. The study was concluded expansion of agriculture, seasonal fire, overgrazing, drought, sand marching and desertification are important factors that effect on plant diversity in the study area. The study recommended protection of rangeland needs to be by improvement of the extension services, management of rangeland through opening of fire lines. Development and improvement, plant diversity and demarcation of routes relevant ministries is essential.
