“…Beside the churches owned forests, other patches of forests are owned by the regional government. Some of the studied dry evergreen afromontane forest patches include the following: Yegof forest in South Wollo Zone [38,39], Wof Washa forest in North Showa Zone [40], Alemsaga Forest in South Gondar Zone [2], Woynwuha Natural Forest in East Gojam Zone [41], Zerat Forest in North Showa Zone [42], Kurib forest in Awi Zone [43], Ylat Forest in North Wollo Zone [44], Amoro forest in West Gojam Zone [45], Zegie Peninsula Forest in north of lake Tana [46], Five forest paches (Apini, Bari, Dabkuli, Katasa, and Tsahare) in Awi Zone [47], and Gatira George's forest in North Wollo Zone [48].…”

Ethiopian dry evergreen afromontane forests are primary biodiversity priority areas including many forest patches of Amhara Region. Natural vegetation of the region is now almost exclusively limited to sacred places, very few protected and less accessible areas. Despite different studies on the various dry evergreen afromontane forest patches of the region, there was not a review work on these forest patches at a regional level. Lack of comprehensive review work creates ambiguity to the understanding of the current status of the forest patches. Scientific information on these forest patches is important for future managerial intervention and sustainable utilization. Thus, the review was aimed to evaluate the status of dry evergreen afromontane forest patches of the Region. Each forest patch contained 15–156 plant species with a total of 525 species under 328 genera and 112 families. Asteraceae was the most species richest family followed by Fabaceae. Most patches harbored considerable number of endemic plant species with a total of 46 species within 44 genera and 26 families. Asteraceae was the most endemic species rich family. Most forest patches had high diversity. Diameter at breast height (DBH) and height class analyses of most forest patches revealed an inverted J-shape pattern. Mean basal area of the forest patches ranged from 1 m2h−1 to 115.36 m2h−1. In most forest patches many number of species were put in low frequency classes. The forests had more seedlings and/or saplings than mature individuals. Although each patch had a rich source of biodiversity, it is influenced by severe anthropogenic disturbances. Therefore, appropriate managerial interventions are required.

“…More research on the population structure of A. schimperiana in this area is required to get a better understanding of future development and challenges. Belay, et al [36] found for their study region in Ethiopia that the population structure of A. schimperiana had a U-shape with more stems in lower and higher diameter classes, showing selective cutting or extraction of medium sized individuals. Potential explanations could be the increased exploitation of A. schimperiana for timber and fuelwood, and its low growth rate [37,40].…”

“…This is especially the case when the tree species are exotic, as their presence in the field is usually due to management rather than natural occurrences. Some other studies also show the importance of shade tree species for coffee production is matched with their planting densities [36,42]. Bukomenko, et al [24], however, found a mismatch between ESs that are important for respondents and the trees they have on their fields.…”

“…Kilimanjaro for the provision of most ESs included in this study. Several studies also report the importance of A. schimperiana for coffee production in Ethiopia [36][37][38]. As a leguminous plant, A. schimperiana can form a symbiotic relationship with rhizobia bacteria to fix atmospheric nitrogen, resulting in increased soil fertility.…”

“…Other studies also show that, with an open wide-spreading crown, A. schimperiana provides good shade cover for coffee production, leading to improved microclimate and coffee yield [26,39]. Another advantage of A. schimperiana is that its leaves emerge in the dry season [36]. This means it can provide shade when there is a lot of sun and prevents coffee from being too densely shaded during the rainy season.…”

Research Highlights: Global coffee production, especially in smallholder farming systems, is vulnerable and must adapt in the face of climate change. To this end, shaded agroforestry systems are a promising strategy. Background and Objectives: Understanding local contexts is a prerequisite for designing locally tailored systems; this can be achieved by utilizing farmers’ knowledge. Our objective is to explore ecosystem services (ESs) provided by different shade tree species as perceived by farmers and possible factors (elevation, gender, and membership in local farmers groups) influencing these perceptions. We related these factors, as well as farmers’ ESs preferences, to planting densities of tree species. Materials and Methods: During interviews with 263 small-scale coffee farmers on the southern slope of Mt. Kilimanjaro, they ranked the most common shade tree species according to perceived provision of the locally most important ESs for coffee farmers. We asked them to estimate the population of each tree species on their coffee fields and to identify the three ESs most important for their household. Results: Food, fodder, and fuelwood emerged as the most important ESs, with 37.8% of the respondents mentioning all three as priorities. Density of tree species perceived to provide these three ESs were significantly higher for farmers prioritizing these services compared to farmers that did not consider all three ESs in their top three. Albizia schimperiana scored the highest for all rankings of regulatory ESs such as coffee yield improvement, quality shade provision, and soil fertility improvement. Influence of elevation, gender, and farmer group affiliation was negligible for all rankings. Conclusions: This study shows the need to understand factors underlying farmers’ management decisions before recommending shade tree species. Our results led to the upgrade of the online tool (shadetreeadvice.org) which generates lists of potential common shade tree species tailored to local ecological context considering individual farmers’ needs.

Specialty coffee (SC) production enables farmers to earn premium prices for high-quality coffee. In Bolivia, some coffee-based agroforestry systems (CAFS) produce SC. However, while many Bolivian families' livelihoods depend on coffee, studies on SC-producing CAFS remain scarce. Yet, research on tree diversity, CAFS management and the factors affecting tree diversity can offer novel insights on agroforestry. We sampled 24 farms in three villages located in the Caranavi municipality. We analyzed farms main characteristics, biophysical variables, shade tree diversity, tree uses, management practices and farmers' socioeconomic background. Additionally, we surveyed 50 coffee farmers to collect information about their preferences for shade tree species and tree characteristics. Then, we investigated if farmers' socioeconomic and farm biophysical variables affect CAFS tree species richness and tree density using generalized linear models (GLM). Our results showed that studied farms are small and certi ed properties (average: 2.6 ha) managed by families; we observed that CAFS provide farmers with valuable products besides SC. We identi ed 85 tree species that provide principally shade for coffee and fruits, timber, lumber and medicines. Moreover, farmers prefer mostly shade tree species that offer them useful and marketable products, while tree characteristics are preferred according to their bene ts to coffee and farmers. GLM revealed that socioeconomic and biophysical variables related to management and landscape composition affect: tree species richness and density. These results suggest that management and landscape are in uential factors driving CAFS tree diversity. Hence, factors fostering farmers' ability to manage their CAFS for biodiversity and household wellbeing should be promoted.
