    Ethnobotanical study of medicinal plants used for the treatment of human and livestock diseases in Kokir Gedebano Gutazer Welene Woreda Gurage Zone and Central Ethiopia
    (Wolkite University, 2025-02-01) Tariku Melis Dode
    In an ethnobotanical survey conducted designated rural and urban areas, randomly chosen sites were to find the most skilled practitioners who are familiar with treating human illnesses with traditional medicinal plants. This ethnobotanical study focuses on medicinal plants used for treating diseases in both humans and livestock in Kokir Gedebano Gutazer Welene Woreda, located in the Gurage Zone of Central Ethiopia. The study aimed to identify the diversity of medicinal plants and their applications in healthcare. Utilizing adescriptive research design, qualitative and quantitative methods were employed the study employed a combination of simple random sampling and purposive sampling techniques. Data collection methods included field visits, interviews, and participant observation. From the 34 kebeles in Kokir Gedebano Woreda, three kebeles were selected based on their agro-climatic zones: Ambelta Kebele lowland Tilamo Kebele midland, and Kentwat in highland. Research design descriptive research method was used because descriptive method used to describe research was qualitative and quantitative approaches The majority of medicinal plants were found in cultivated areas, with fewer collected from natural environ in average the three kebele medicinal plants of cultivated land (77.43%) forest (22.53%). Regard to plant families, the highest species richness consisting of 6 (8.69%) family solanaceae, Fabaceae, Rutaceae decrease respectively and Lamiaceae 5 (5.79%) each families and next families Cucurbitaceae, Rosaceae and Asteraceae 4 (4.34%) each families.ments. Additionally market surveys, focus group discussions, and ethnobotanical data analysis. Preference ranking and informant consensus factors were assessed using the Informant to evaluate the effectiveness of the medicinal plants across various disease categories. The research area's medicinal plant variety was determined by collecting and identifying 71 species of medicinal plants from 64 genera and 40 families. The cultivated land was where the majority of the medicinal plants were gathered, 54 medicinal plant species gathered in the study area were used to cure human ailments, while 15 were used to treat cattle ailments, and 13 were used to treat both. Both official and informal education systems should incorporate tested and validated indigenous knowledge indigenous about the traditional uses of plants in general and therapeutic applications.

    AN INVESTIGATION OF WOODY SPECIES CONTRIBUTION FOR AGROFORESTERY AND COMMUNITY MANAGEMENT PRACTICE IN MISRAK MESKAN DISTRICT OF MISRAK GURAGE ZONE CENTRAL ETHIOPIA REGIONAL STATE ETHIOPIA
    (Wolkite University, 2024-12-01) MOHAMMED KEDIR
    Woody species conservation is an issue of scientific, economic and ecological concern at global level.Woody species play many functions and make a real contribution to farmland protection, making them essential parts of an agroforestry system.Farmland plays significant role in the woody species conservation. The study was conducted to An Investigation of Woody Species Contribution For Agroforestery And Community Management Practice In Misrak Meskan District Of Misrak Gurage Zone Central Ethiopia Regional State, Ethiopia.Using systematic sampling techniques were representative kebele were selected from district . Four kebele and a total of 400 households were included in the study. Data on woody species were collected using a line transect across 60 plots, each measuring 40m × 40 m, spaced at 100 m intervals on farmland. For all woody species ≥5 cm, the diameter at breast height (DBH) was measured. Key materics such as important value index, density, dominance, and frequency were computed and analyzed. A total of 20 families and 33 woody species were identified and documented.The average basal area of woody species on farmland in study area was 0.55 m2. Farmers preferred woody species that provided for fuel wood, timber, shade and construction materias, with Fiaderbia albida the most favored, followed by Eucalyptus camaldulensis and Acacia abyssinica. The common management practices include coppicing and Lopping. Socioeconomic aspects like the size of the farm, educational background, and wealth status influenced the management of woody species on farmland.With 6 species, the Fabaceae family was the most represented. Fiaderbia albida., Eucalyptus camadulensis., Acacia abyssinica., Balanites aegyptiaca., and Cordia Africana. were the most common species, occurring in 85%, 80%, 76%, 68.33%, and 65% of the farms that were sampled.Overall, the study demonstrated that an agroforestry system is essential to the preservation of woody species.While farmers employ traditional management practice for wood species on their farmland,these practices required better support and extention service to address existing challenges.

    FLORSTIC COMPOSITIONVEGETATION STRUCTURE AND MANAGEMENT PRACTICES IN ZARA NATURAL FOREST IN GETA WOREDA DISTRICT GURAGE ZONE, CENTRAL ETHIOPIA REGION STATE, ETHIOPA.
    (Wolkite University, 2025-01-01) JILALU HASSEN
    This research was conducted in the Zara Natural Forest to evaluate the diversity of plant species, the structure of the vegetation, and the management practices aimed at conserving the forest. There is a notable absence of documentation concerning plant composition, conservation efforts, and management strategies in the area, as no previous floristic studies have been performed on the dry Afromontane vegetation in the district. The study employed a systematic sampling method, collecting vegetation data from 45 quadrats, each measuring 20m by 20m and spaced 100m apart along four transect lines. These transect lines were established every 500m from each direction within the study area. Additionally, smaller plots of 2m x 2m were created within each major plot for collecting herbaceous data. All plant species within each quadrat were recorded, leading to the identification of 66 plant species across 54 genera and 40 families. Of these, 35% were trees, 33% were shrubs, 23% were herbs, and 9% were climbers. The Fabaceae family was the most prominent, featuring eight species, followed by Astraceae with seven species, Rosaceae with four species, and both Euphorbiaceae and Solanaceae with three species each. The remaining thirty-five families were represented by either one or two species. The forest's total basal area and density were recorded at 19.58 m²/ha and 2542.94 stems/ha, respectively. An analysis of the importance value index revealed that Juniperus procera (59.74%) is the most frequent and dominant species, followed by Podocarpus falcatus (39.55%) and Calpurnia aurea (34.98%). This forest type is more associated with dry Afromontane forests and has a promising start in terms of protection and conservation efforts. Community participation in these efforts was at a moderate level. The study of the forest's regeneration status indicated a low level of regeneration. It is recommended to implement a community-based participatory forest management program to enhance the successful conservation of the Zara natural forest.
