“…However, the implanting of Eucalyptus globules along farm boundaries, homesteads, and roadsides with various spatial patterns considered to have ecological effects (Aklilu et al, 2019;Kidanu et al, 2005;Zegeye, 2010;Zerga, 2016;Zewdie, 2008). For example, compared to other tree species, Eucalyptus globules desiccates watercourses (Alemie, 2009;Bauhus et al, 2000;Kidanu et al, 2005) and suppresses germination of understory plants through its allele-chemicals (Akbar et al, 1990;Asmare, 2020;Lisanework & Michelsen, 1993).…”

The expansion of Eucalyptus globules boundary plantation (EGBP) along farm boundaries considered to have effects on yield of underneath crops. Tree root pruning or trench is a potential tool for managing belowground competition. We evaluated aspect and trench distance effect of EGBP on barley yield and soil physicochemical properties in Gummer woreda, central Ethiopia. Two months before sowing, on one side of each aspect of EGBP trenches were prepared at distances of 0.5m, 1m and 1.5m using split-split plot design with three replications. At 1.5m trench distance, the North faced field showed 20.4%to 31.2% additional yield variation respectto South, East and West faced fields. Also 15.2% to 43% additional yield was observed as the field distance from EGBP increased from 3m to 12m. Relative to un-trenched field, trenched fields showed 31.9% to 73.4%additional yield variations. Regarding to soil physicochemical properties, aspect of EGBP had no significant effect. However, except for texture, pH and extractable potassium, trench showed a significant difference on soil organic matter, total nitrogen, available Phosphors and CEC status. Relative to un-trenched fields of 6m and 9m, 1.5 m trenched field of 3m field distance showed 48 % and 15% additional yield variations. That means root trench minimized on average 24% of the field distance effect of EGBP on barley yield. Therefore, root pruning at 1.5m distance from EGBP using 0.5m x 0.5 m trench is an applicable and advisable method that will help farmers to maximize barley yield with higher land-use efficiency.

Unique bird diversity in an Ethiopian church forest

Today, most of Ethiopia’s church forests are small forest patches surrounded by a degraded and anthropogenically modified landscape, mostly arable land. Nevertheless, these forest islands may still provide valuable habitats for typical forest species. It remains questionable whether these habitat remnants provide sufficient resources for forest species to successfully reproduce and persist in the long run. In this study, we assessed bird species based on point-counts in and around Tara Gedam Church Forest in northern Ethiopia. We observed birds in typical natural evergreen Afromontane forest (forest interior and forest edge) and in anthropogenic habitats, the semi-natural shrublands, agricultural land, and Eucalyptus tree plantations. We assigned ecological and behavioural characteristics to each of the bird species observed. Our results point to a specific bird community restricted to the forest interior and characterized by forest generalists and forest specialist birds. Along the forest edge, a mix of forest generalists and species of the open landscape can be found, creating mixed communities with high species overlap. The highest number of species was observed at the forest edge and in semi-natural shrubland, where both, open-land and forest species were found. On the other hand, the total number of species in the forest interior was comparatively low, with insectivorous and frugivorous typical forest species. Our results underline the fact that even small forest remnants are important for the conservation of forest species, which do not evade surrogate forest habitats.
