The impact assessment of direct fence with some treatments on rangeland improvement in Semi –Arid area - - Sudan

Abstract

The study was conducted at Babanousa area in West Kordofan State the aim of this study was to assess the impact of direct fence with some treatments on rangeland improvement. The rangelands were divided into four blocks A, B, C and D. the three blocks (A, B, C) were replicated in three sites, block D was taken in open rangeland in three sites used as control. Eighty quadrate samples were taken in the each sites, twenty quadrates for each block were placed in ten meter along transect during two rainy seasons. The three blocks (A, B, C) were treated by different improvement process. For vegetation measurements the quadrate method (Wilm et al, 1944) was used to study the differences in biomass productivity, vegetation cover, and plants diversity. The data obtained were analyzed to compare between the improved blocks A, B and C and the opened area (D control) using stander equations. The results showed that, the average percentages of the three fenced rangeland were higher than opened one in term of ground cover, in addition to twenty sex deferent plant species were found in the three fenced rangeland most of them were desirable plants, while eighteen deferent plant species has been found in open rangeland with more undesirable plant species. Also, the results showed differences in average plant density in the three fenced rangeland that 97 plant/meter² were found, while the average plants density in open rangeland were 62 p/m².
