Abstract: An ethnobotanical study on uses and management of traditional medicinal plants by indigenous people in 'Boosat' Wereda has been conducted in Welinciti area, East Shewa Zone, Oromia Region between July 2000 and March 2001 to make inventory of plants that have ethnomedicinal value and investigate the uses and management practices by local people. Five study sites were systematically established to include areas inhabited by settled farmers and transhuman pastoralists. Eighty informants were randomly selected from age group 15 to 40 years and above from both males and females. Vegetation was examined and the dominant species of vegetation visually recognized were documented. The eight vegetation types identified were: Acacia albidaZiziphus spina-christi woodland, Acacia senegal-Acacia tortilis dominated vegetation, the Pistacia falcata, Acacia seyal-Acacia tortilis and Cissus quadrangularis, Boswellia papyrifera, Euphorbia nigrispinoides, Acacia Senegal thicket vegetation and Acacia tortilis-Balanites aegyptiaca woodland. Ethnobotanical information of medicinal plants including uses, management and conservation by indigenous people, land, soil and vegetation classification by indigenous people were obtained from informants by semi-structured interview, observations, group discussions, guided fieldwalks. A total of 81 medicinal plant species distributed in 66 genera and 34 families were documented. Of these, 29 species are used to treat 18 livestock diseases while 52 are used to treat 43 human diseases. Habits of medicinal plants include shrubs 41(50,6%), herbs 17(21%), trees 15 (18.5%), climbers 7(8.6%) and hemiparasites 1(1.2%). Roots are the most frequently used plant parts accounting for 49 (31.4%) of the preparation followed by leaves 38 (24.4%). There were 23 different preparation methods reported. Howevere, the most widely used method of preparation is crushing, pounding and mixing with cold water to serve as a drink 43 (24.3%). Eighten (10.2%) of the preparations are made by concoction of different parts of a plant or different part of the same plant. There is diverse indigenous ethnomedicinal knowledge in the area. Men and women of age above 40 knew 80 (98.8%) of the 81 species while people of age between 15 to 40 years knew 37 (45.7%). Modernization and acculturation have contributed in making the younger generation unwilling to practice, retain traditional knowledge and consider it as less important. Paired comparison and preference ranking showed that people have preferences for some species over the other in treating the same ailment. Environmental degradation, habitat changes fueled by production of charcoal, collection of fuel wood construction material and agricultural intensification are major threats to medicinal plants and knowledge on them. It was found that, there is little practice of bringing medicinal plants under cultivation. Indigenous practices, various cultural and seasonal restrictions of collecting medicinal plants have contributed to the management and conservation of medicinal plants in the area. It is therefore, recommened that the indigenous knowledge and practices be blended with the formal sector to ensure sustainable use, management and conservation of the important medicinal plants in particular and the biota in general. Furthermore, traditional community based in-situ conservation should be complemented with ex-situ conservation with the participation of indigenous people.
