Despite shrinking pastureland in the central highlands of Ethiopia, as a result of cropping, there has been little detailed work to evaluate effects of traditional grazing land management practices on vegetation and soil attributes. This study aimed to quantify vegetation structure, aboveground biomass yield and soil quality, as a result of the impact of enclosure and open access management practices by using a sampling quadrat. Aboveground biomass yield for the grass species was 17.6 and 31.2% higher, respectively, for the highland and mid-highland agro-ecologies for enclosed areas, compared with open-access grazing. Andropogon amethystinus (Important value index (IVI) = 86.9) and Pennisetum thunbergii (IVI = 79.2), the most dominant and highest density, found in the enclosed areas decreased from open access grazing land and replaced by more resistant to continuous heavy grazing, like Eleusine floccifolia (IVI = 125.7) in the mid-highland area. Herbaceous species richness was better in open access grazing land than the enclosed areas. Soil quality parameters, such as total nitrogen, available phosphorous, calcium, sodium and cation exchange capacity, were significantly higher for enclosed areas than open access practice. In conclusion, enclosed areas performed greater in most of the parameters considered than open access grazing land management practices at both agro-ecologies.

尽管埃塞俄比亚中部高地的牧场由于种植而缩小，但几乎没有详细的工作来评估传统牧场管理做法对植被和土壤属性的影响。本研究旨在量化植被结构、地上生物量产量和土壤质量，这是通过使用采样样方进行的封闭和开放式管理实践影响的结果。与开放式放牧相比，封闭区域的高原和中高原农业生态草种的地上生物量产量分别高出 17.6% 和 31.2%。Andropogon amethystinus（重要价值指数 (IVI) = 86.9）和Pennisetum thunbergii(IVI = 79.2)，在封闭区域中发现的最主要和最高密度，从开放式牧场减少，取而代之的是对连续重放牧的抵抗力更强的，如中高地地区的Eleusine floccifolia (IVI = 125.7)。开放式牧场的草本物种丰富度优于封闭区域。封闭区域的土壤质量参数，例如总氮、有效磷、钙、钠和阳离子交换能力，明显高于开放区域。总之，在两种农业生态系统中，封闭区域在所考虑的大多数参数中的表现都优于开放式牧场管理实践。
