- Abstract
The purpose of this study was to investigate the floristic diversity and productivity of managed rangelands in the Main Ethiopian Rift (MER). The relationships between forage production and plant diversity among four native range sites (i.e. Alagae hay-field, Alagae woodland, Neteli hay-field and Neteli woodland) that were different in range condition were examined. The major variables studied include floristic diversity, herbaceous biomass production and range condition assessment. A total of 213 species, representing 143 genera and 40 families, were identified from the study sites. The range conditions ranked from poor to good. Herbaceous biomass production followed a quadratic relationship with range condition. The humpback model was tested and found to be applicable to the MER rangelands. The study results reflect on the need for optimizing productivity and biodiversity conservation and put emphasis on the need for integrating agricultural production and biodiversity conservation interests for the sustainable utilization of rangelands.
