Question: Thousands of small isolated forest fragments remain around churches ("church forests") in the almost completely deforested Ethiopian Highlands. We questioned how structure and composition varied with altitude, area human influence. Location: South Gondar, Amhara National Regional State, Northern Ethiopia. Methods: The species was assessed for 810 plots 28 church forests. All woody plants were inventoried, identified measured (stem diameter) seven to 56 10 m x 10-m per forest....
ABSTRACT In the northern highlands of Ethiopia, patchy remnants old-aged Afromontane forests can be found around Ethiopian Orthodox Tewahido Churches (EOTC). These are sanctuaries for different plants and animals that have disappeared in most parts Ethiopia. Studies documented information on their bio-physical features socio-economic setting either scanty or totally lacking. Vegetation surveys were carried out eight church North Gonder Administrative Zone, Northern Ethiopia to record * size,...
Species of the genus <em>Eucalyptus</em> (common name eucalyptus) are widely planted all across Ethiopia—including on large areas land previously allocated to food production. In recent decades eucalyptus has also increasingly been lands around and within “church forests,” sacred groves old-aged Afromontane trees surrounding Ethiopian Orthodox Tewahido churches. These revered holy sites have long recognized for their cultural values ecosystem services—including potential support species...
ABSTRACT Tree regeneration is severely hampered in the fragmented afromontane forests of northern Ethiopia. We explored how trees regenerate remnant along gradient from open field, forest edge to closed sites and canopy gaps inside forest. investigated effects seed sowing, litter removal, weeding on success this gradient. Regeneration was for four indigenous tree species, measured terms seedling establishment, growth, survival. Species performed differently according site conditions. Within...
Forest fragmentation is globally pervasive but especially severe in tropical forests, as exemplified by the state of Afrotropical montane forests Ethiopia, where remnant almost exclusively exists small, isolated fragments centered around churches, forming networks partially intact 'habitat islands.' Church deliver ecosystem services such forest products and erosion control, are considered a benchmark for assessing biodiversity quality. However, safeguarding church integrity necessitates...
Well‐controlled landscape experiments have played key roles in advancing fragmentation science, but such are costly and may not be possible many ecosystems – including the long‐inhabited landscapes typical of developing countries. In contexts observational studies pre‐existing forest patches offer valuable insights, these bring other challenges non‐random location patches, heterogeneous matrix between patch‐specific management practices that influence community composition. This paper argues...
We investigate the event runoff response in six sub-catchments Lake Tana sub-basin, headwater of Blue Nile basin, northwest Ethiopia. Steep and mountainous terrains surround floodplains, imposing soil erosion upper catchments flooding sedimentation at floodplains. This study was conducted upland source catchments. The focus is to catchment characteristics that control catchments, how recent land management practices may have contributed improved hydrological conditions. Event rainfall data...
Abstract Nutrient balance analysis provides essential information concerning the current nutrient status of soils and used to take appropriate replenishment practices. flows were analyzed in Enqulal watershed Dera district, Northwestern Ethiopia cropping season 2018. Direct measurement empirical formulas identifying measuring major inputs outputs NPK from different land uses within catchments. Four (Mineral fertilizer, Organic Atmospheric deposition Nitrogen fixation) five (Crop yield, Crop...
Birds are vital bioindicators of biodiversity and ecosystem health, but their persistence ecological roles under severe threat from human activities in the Lake Tana Basin, Ethiopia. Rapid land forest degradation driven by agricultural expansion, urbanization, rising demand for fuelwood imperil avian community structure functions this region. However, amidst challenge, church forests have emerged as crucial sanctuaries. Despite small size isolation each other mainly land-use, these provide...
Abstract Two new oribatid mite species, Austrocarabodes (Uluguroides) kluttzi Ermilov, Winchester, Lowman & Wassie sp. nov. (Carabodidae) and Pilobatella lowmanae Winchester (Haplozetidae), are described from Afro-montane forests in the northern highlands of Ethiopia. An identification key to all known species is given. annotated checklist identified taxa sampled this studyis presented. Fourteen six genera three families recorded for first time
Abstract Almost all dry Afromontane forests of Northern Ethiopia have been converted to agricultural, grazing or scrub lands except for small fragments left around churches (‘Church forests’). Species regeneration in these is limited. We investigated (i) how intense postdispersal seed predation was church forest, and if this varied with species and/or habitat, (ii) long tree seeds maintained their viability while buried forest soil. In the experiment, we monitored six four habitats a period...
Abstract Land degradation due to soil erosion presents a major challenge for sustainable development. We investigated run‐off and sediment yield (SY) dynamics in the northwestern highlands of Ethiopia. The study area included 14 zero‐order catchments with surface ranging from 324 1715 m 2 . V‐notch weirs produced plastic jars were introduced as measuring alternatives that met local constraints. Run‐off (RO) depth at weir was registered manually 5‐min intervals during two rainy seasons 2018...
