Most of the dry lands of Ethiopia host woodlands that produce various commercial gum-resin products. The objective of this study was to investigate the social and economic importance of commercial gum-resin products focusing on their roles in the local livelihoods. Four kebeles, namely, Luka and Enchete from Bena-Tsemay district, and Erbore and Asele from Hamer district of South Omo Zone, were purposively selected for the collection of socioeconomic data. Semistructured questionnaire and checklists were used for households and key informant interviews and focus group discussions, respectively. In addition, market assessments and field observation were conducted to collect the primary data and supplemented with secondary data. A total of 80 households were randomly selected for one-to-one interviews from the total number of 425 households in the selected keb...

The main objective of this study was to identify better provenance for indigenous trees by testing seed germination and seedling traits. Seeds of six indigenous trees (Vachellia abyssinica, Vachellia seyal, Faidherbia albida, Balanites aegyptiaca and Terminalia laxiflora Engl.) were collected from different geographic areas. One hundred (100) polyethylene pots (20 cm height and 12 cm diameter) were filled with 2:1:1 ratio of local, forest soil and sand composition for seedlings. A Complete Randomized Design (CRD), 5 x 4 polyethylene pots in four replications of 20 polyethylene pots for each provenance was designed in the nursery and the provenances for selected species. Different early growth performance parameters were measured for each tested provenance. All collected data were analyzed by using ANOVA while th...

Moringa stenopetala, Terminalia brownii, Morus alba, Melia azedarach, and Sesbania sesban were used for this study. Square quadrants of 16 m2 plot sizes were established with the RCBD of three replications. Seedlings were planted with 1 m × 1 m spacing between rows and plants respectively. The growth and chemical composition of the studied tree/shrub species were evaluated with one way ANOVA. The growth parameters and nutrient composition of the studied fodder tree/shrub species are significantly (P ≤ 0.05) varied. The nutrient composition of the studied tree/shrub species ranged between percentages of 88.3 - 90.6 of Dry Matter, 5.7 - 13 of Ash, 12.45 - 22.35 of Crude Protein, 11.8 – 23.5 of Acid Detergent Fiber and 18.1 - 33.6 of Neutral Detergent Fiber. S. sesban and M. stenopetala are the consistent and superior tree/s...

The status of populations of B. neglecta was assessed by examining the density, abundance, frequency, dominance, importance value index, and population structure. Resin sample was analyzed for the physicochemical properties. The composition of the essential oil was analyzed with Gas Chromatography-Mass Spectrometry. The high values of density, abundance, frequency, dominance, and importance value index for B. neglecta showed the potential of the tree for bulk resin collection. Boswellia neglecta had a bell-shaped diameter distribution indicating a hampered regeneration. The B. neglecta resin had a moisture content of 2.68%, ash content of 0.99%, pH of 5.7, and oil yield of 5.92%. The resin possessed good quality as compared to resins in other reports. The essential oil was optically active (−31.6° at 23.2°C). The essential oil contained several compounds, but 71.1% of the composition were formed mainly from methyl oleate, methyl linoleate, methyl palmitate, which have not been reported from B. neglecta. Sustainable management must be enacted since the agro-pastoralist mode of life hinders regeneration of the species and its resin resources.
