“…They provide more than one significant benefit to the production or service functions of the land-use system. Mostly the people of Ethiopia cultivate indigenous tree species to provide food, charcoal, timber, fuel-wood and farm implements (Robi and Edris, 2017;Solomon and Moon, 2018). When deciding to retain trees, farmers consider different benefits and services which include income generation through selling timber, food in the form of fruit, fuelwood and other watershed benefits such as soil conservation and soil fertility improvement (Etefa et al, 2014).…”

Tree planting has a long history in Ethiopia and managing indigenous multipurpose trees is widely adopted by farmers, as a dominant feature of agricultural landscapes. Farmers manage different indigenous multipurpose tree species within agroforestry practices. But variability in agroecological conditions causes inconsistency on tree species selection, their intended benefits and ecological services. Management practices and current constraints on them were also the major issues on indigenous multipurpose agroforestry tree species in Ethiopia. Therefore, this article was initiated to review on indigenous multipurpose agroforestry tree species in Ethiopia, management practices applied to them, their productive and service roles and constraints. It found that Cordia africana, Millettia ferruginea, Erythrina brucei and Olea capensis are the major indigenous multipurpose tree species used in agroforestry systems in southern Ethiopia. Croton macrostachyus, Vernonia amygdalina, Faidherbia albida, Acacia nilotica, Acacia seyal and Grewia bicolour are found in the northern part of Ethiopia. Albizia gummifera, Cordia africana , Croton macrostachyus , Ficus vasta and Vernonia amygdalina are also found in the central highlands of Ethiopia. They are established through natural regeneration and farmers apply pruning, pollarding and coppicing tree management practices to harmonize their survival with integrated crops. Fruit, fodder, wood, timber and cash generation are the major productive roles of these tree species. In addition to these, they also have agroecological services through improving soil fertility, controlling erosion, mitigating climate change and conserving biological diversity. Despite their considerable uses and services; inadequate research and extension; shortage of knowledge; the expansion of cash crops and the small size of land holdings constrain the sustainability of these tree species. The government could encourage the wider use of agroforestry practices by policies to expand research and extension services. In addition to this, policy makers and agricultural development interventions should be encouraged to make more informed decisions regarding further research on indigenous multipurpose tree species in Ethiopia.

“…Over-exploitation is the second limitation to regeneration and cutting trees for charcoal, firewood, house construction, and timber can severely destroy the understory/seedlings of mature tree species in the study area. Moreover, previous studies elsewhere found that overexploitation, climate change, drought, expansion of exotic species, and biotic factors had an impact on the regeneration of native species in Ethiopia (Tefera et al, 2014;Robi and Edris, 2017).…”

“…Native tree species in traditional agroforestry practices provide various products and services. They provide products such as timber, wood for construction, firewood, farm implements, fodder (leaves), and fruit as a source of income (Negash et al, 2012;Robi and Edris, 2017;Gemechu et al, 2021;Molla et al, 2023). Ecological services include soil fertility improvement, biodiversity conservation, and carbon sequestration (Negash et al, 2012;Gebrewahid et al, 2018;Gebre et al, 2019).…”

Native fodder and fruit species provide various products and services to local communities besides their fruit (food) and fodder supply in our country including in the study area. Although, there is rich traditional knowledge on propagation methods of native fodder and fruit species and their local use, but little recognition has been given by forestry research and extension efforts to enhance them. The general objective of the study was to investigate the use value and propagation methods of native fodder and fruit species in the Merhabete district, Ethiopia. A total of 127 households were randomly selected and interviewed about local use and propagation methods of native fodder and fruit species. The study indicated that the majority of native fodder and fruit species were used for firewood (23.9%) followed by charcoal (10.9%), timber, and construction wood (10.6%), fencing (9.3%), soil fertility improvement (9.1%), farm tool (7.1%), and medicine (3.3%). Native fodder and fruit species (42.7%) were propagated through wilding (natural regeneration) and the remainder were propagated through seedlings (7.2%), seed (6.06%), and stem cutting (4.8%). Overgrazing (46.5%) followed by overexploitation (22%), climate change/drought (20.5%), and disease and pest (11%) were the major regeneration constraints to native fodder and fruit trees/shrubs species in the study area. Therefore, proper involvement either through research or development works are essential to reduce the propagation constraint of studied species. Ziziphus spina-christi (L.) Desf. followed by Faidherbia albida (Delile) A. Chev., Cordia africana Lam., Ximenia americana L., and Acacia senegal (L.) Willd. were the most preferred species for planting by farmers in the study area. Domestication should focus on the preferred top five species to promote species conservation and sustainable use.

“…Moreover, the domestication and integration of IFT into agroforestry system have several bene ts (Negash 2010). Similarly, farmers in different parts of Ethiopia, usually integrate diverse IFT species into their farms as their routine practices for different purposes (Robi and Edris 2017). Additionally, when deciding to retain trees, farmers consider the different bene ts and ecosystem services of tress as a source of income generation through selling timber, source of food in the form of fruit, source of fuel wood and keep them for other watershed bene ts such as soil conservation and soil fertility improvement (Etefa et al 2014).…”

Fodder trees are integral components of agroforestry system in the tropics. Indigenous fodder trees (IFT) are grown in Sidama, Ethiopia, for different purposes. However, their composition, biomass yield and socioeconomic importance are inadequately studied. The objective of this study was to assess species composition, biomass yield and socioeconomic contribution of IFT. Three districts and 12 kebeles were purposively selected, from which 273 households were randomly selected for household survey. Sixty households were randomly selected for inventory within nested quadrats of 20 x 20 m. Twenty eight IFT species belonging to 26 genera and 24 families were identified in three agro ecologies. Species richness in lowland (11.08) was significantly higher than highland (9.6) and midland (7.7) (p < 0.001). Similarly, lowland (1.5) was significantly more diverse than midland (1.2) and highland (0.8) (p < 0.001). Arundinaria alpine, Hygenia abyssinica and Erythrina brucei were dominant IFT, altogether accounted for 72.35% of the total basal area. In midland, Cordial africana, Ficus sur, Dracaena steudneri and Melleitia ferruginea were dominant species, and Acacia albida, Acacia tortolis, Balanites aegyptiaca and Cordia africana were dominant in lowland, altogether accounting for 56.1 and 76.72% of the total basal area, respectively. Biomass yield were significantly different (p < 0.05) among agro ecologies. E. brucei, D. steudneri and C. africana had the highest biomass yield in highland, midland and lowland, respectively. Farmers with large land size, small family size, practicing agroforestry, having awareness and interest about fodder trees had significantly affected the decision to have IFT. In addition to fodder supply, IFT contribute to soil fertility improvement, income source and timber production. Hence, the dominant IFT are important for maintaining biodiversity and contribute as a feed source. Further research is recommended to evaluate the nutritive value of IFT.
