Received 2 February, 2015; Accepted 16 March, 2015 Traditional medicine has continued to be the most affordable and easily accessible source of treatment in the primary healthcare system of Ethiopia. However, the medicinal plants used for such treatments are becoming increasingly rare and vulnerable to extinction because of improper utilization and conservation practices. Hence, this reseach was initiated with the aim to assess the use, management and conservation practices of medicinal plants in some selected districts of Jimma Zone, south west Ethiopia. Ethnobotanical methods such as focus group discussions, key informant interview, semistructured interview and field walks were used to collect ethnobotanical data on use and management practices of medicinal plants in the study area. Data collected were classified into the use of the plants and management practice. Data of the semistructured interview was analyzed using SPSS version 16 software. The result revealed that a total of 67 plant species were identified in the study area, of which 30 are nutraceuticals, 30 are collected at wild habitat and 37 are cultivated. Source of medicinal plants include: cultivation in home gardens, live fences, crop fields and wild collection from the nearby environment. The cultivation practice include home gardens, mixed in field crops, live fences and agro- forestry. About 87% of respondents explained that they get medicinal plants easily in the study area and 10% explained that it is difficult. About 76% of respondents explained that medicinal plants are not sold in the market and 23% responded marketability of medicinal plants. About 33% of informants explained that medicinal plants are under threat and 67% explained that they are not threatened. Focus group discussion and key informant interview revealed that people conserve medicinal plant in live fences, home gardens, and they cultivate some species because of their nutraceutical value. They interpreted that there is no specific conservation activities targeted to medicinal planted by extension program. This indicates the necessary strategy and conservation of medicinal plants in the study area. Postharvest handling is not commonly known for many medicinal plants because they are collected and used immediately. Therefore, local people use their knowledge nowadays in this region. The resources require an urgent attention in research and policy which should include training on knowledge of medicinal plants use and management in cultivating, production, postharvest handling, promoting their use and sustainable utilization.

The need is and easily accessible source of treatment in the primary more pressing for resource poor communities and the local Feyssa et al. 203 therapy is the only means of medical treatment for such of medicinal plants was carried out by Awas and Demissew communities (Haile and Delenasaw, 2007). These medical in southwestern Ethiopia (2009). However, there is no systems are heavily dependent on various plant species comprehensive systematic study on the use and conser- and plant based products (Jansen, 1981). It is estimated vation practices of medicinal plants in the current study that 70–80% of people worldwide rely chiefly on traditional, districts. These demanded an urgent attention to conserve largely herbal; medicines need to meet their primary such vital resources. Therefore, this study was proposed healthcare (Farnsworth and Soejarto, 1991; Pei, 2001). to assess the use, management and conservation practices The list of medicinal plants in Ethiopia, which is of medicinal plants in some selected districts of Jimma documented for National Biodiversity Strategy and Action Zone, South West Ethiopia. Plan by Tesema et al. (2002) shows that about 887 plant species were reported to be utilized in traditional medicine. MATERIALS AND METHODS Among these, 26 species are endemic and they are becoming increasingly rare and are at the verge of Study site extinction. It is believed that the greater concentrations of these plants are found in the southern and southwestern The study was conducted in Jimma Zone (Manna, SeqaChekorsa parts of the country following the concentration of and Kersa) districts in Oromia National Regional State, Southwestern Ethiopia where 3 peasant associations were selected from each biological and cultural diversity (Yineger, 2005; UNEP, district. 1995). In Ethiopia, most of the medicinal plants used by herbalists are collected in the natural vegetation (Asfaw, Geographical location of the study area 1999, 2001). Medicinal plants obtained at wild habitats Manna, SeqaChekorsa and Kersa districts are located in Jimma in are found in different natural ecosystems of the forests, southwestern Ethiopia. It is one of thr zone of the Oromia National grasslands, woodlands, wetlands, in field margins and Regional State. It has a latitude and longitude of 7°40′N 36°50′E garden fences, as weeds and in many other microhabitats respectively. where they are harvested when the need arises. These are free access resources. Many medicinal plants are Population also harvested for non-medicinal purposes such as for timber, implements, firewood and other purposes, and Total population of the districts is: Kersa 165,331(83579 male and hence they are subjected to multiple depletion. Hence, 82,812 female); Mana, 146, 67 (74,512 male and 71,878 female); sustainable utilization measures and conservation of Seka Chekorsa, 208,096 (104,758 male and 103,338 female). plants should target the habitats of such vulnerable species. Vegetation Except in a few medicinal plant species where a few food crops are cultivated with medicinal value, there is no The study area lies in moist evergreen montane forest of Jimma organized cultivation of plants for medicinal purposes in zone in south western Ethiopia and this specific study was Ethiopia.

However, there is a potential in the future for increased demand for some species, and therefore it is important to Ethnic group identify them and start the necessary research on the In Seka Chekorsa, Mana and Kersa districts the five major ethnic conservation and sustainable utilization techniques groups are Oromo the Yem, Amhara, Kafficho and Dawuro.
