| dc.description.abstract | Rangeland management aimed at animal production can reduce, maintain or even increase range plants diversity. Although the maintenance of biodiversity has become one of the goals in ecosystem management, the relationship between diversity and ecosystem characteristics such as level of herbivory, productivity, and vegetation structure are still poorly understood. The way that management actions constrain (or perhaps magnify) rangeland biodiversity must clearly be understood for sustaining both productivity and biodiversity in rangelands. The purpose of this study was to investigate the floristic diversity and productivity aspects of protected aJId/or managed rangelands in the Main Ethiopian Rift (MER), semi arid agI'o ecological zone. In this paper, the major issues addressed include floristic diversity, vegetation description, herbaceous biomass estimation, and range condition assessment. For the study we used a combination of ecological survey (Zurich Montpelier) method and a standard range condition assessment technique (adopted for the South-Eastern Ethiopian Rangelands). TWINSPAN computer program is used to make vegetation classifications. We examined the relationships between herbaceous biomass production and plant diversity in four native range sites differing in range condition in the Open Grasslands (2), and Wooded Grasslands (2) in semi-arid AEZ of MER. The results of this study have revealed the unique vegetation and rich plant diversity of the two rangelands. Range condition of the four range sites ranged from poor to good and found to be supported by herbaceous biomass production and grazing indicator species. Herbaceous biomass production follows a quadratic relationship with range condition. There is some indication that the humpback model appears to be functional in the MER rangelands. Important information generated has pictured the need for optimizing productivity and biodiversity conservation and elicited information on how agricultural and biodiversity conservation interest should be integrated for the sustainable utilization of rangelands.
