| Abstract: | Agroforestry systems play an important role in biodiversity conservation and climate change mitigation, yet their contribution to aboveground carbon (AGC) storage in smallholder landscapes remains poorly quantified in Ethiopia. This study assessed woody species diversity and aboveground carbon stocks across seven Landuse types (annual croplands, fallows, grazing lands, homesteads, live fences, perennial croplands, and patches of natural forest) in the farmscape of Dallo Manna district, Southeastern Ethiopia. A total of 45 plots were sampled, and tree/shrub biomass was estimated using an established allometric equation. Results revealed that 50 woody species belonging to 33 families were recorded. Vachellia abyssinica and Albizia gummifera were the most frequent, while Coffea arabica was the most abundant species. The study found significant variations in species richness and diversity across the land uses. Perennial croplands showed the highest species richness and diversity, followed by patches of natural forest. Mean aboveground carbon (AGC) stock across the farmscape was 49.21 Mg C ha−1, with the highest per-hectare values observed in perennial croplands (225.43 Mg C ha−1), and homesteads (99.36 Mg C ha−1). Lower AGC values were recorded in annual croplands (23.69 Mg C ha−1). Lower AGC values were recorded in annual croplands (23.69 Mg C ha−1), grazing lands (31.68 Mg C ha−1), fallows (43.84 Mg C ha−1), and live fences (1.13 Mg C ha−1). These findings demonstrate that perennial agroforestry and homestead practices, alongside remnant forests, boost biodiversity and carbon storage, strengthening climate resilience and supporting Ethiopia’s climate mitigation and sustainable land management goals.
