摘要

Ethiopia is one of the major centers of plant diversity and endemism in tropical Africa, owing to its complex topography, wide altitudinal gradients, and diverse climatic conditions. This systematic review synthesizes current knowledge on the distribution, composition, ecosystem services, threats, conservation interventions, and research gaps associated with Ethiopia’s vegetation types. Following the PRISMA guidelines, a comprehensive literature search was conducted using Google Scholar, Scopus, and Web of Science databases for studies published between 2000 and 2024. Of the 1245 records identified, 78 studies met the inclusion criteria and were included in the final synthesis. The review identified 12 major vegetation types, ranging from Afro-alpine ecosystems to desert and semi-desert scrublands. These ecosystems provide essential provisioning, regulating, supporting, and cultural services, including water regulation, carbon sequestration, soil conservation, biodiversity maintenance, livestock forage, timber and non-timber forest products, fisheries, and ecotourism opportunities. However, their ecological integrity is increasingly threatened by agricultural expansion, deforestation, overgrazing, invasive alien species, pollution, altered fire regimes, and climate change. The review further indicates that conservation interventions such as PFM, protected areas, biosphere reserves, area exclosures, watershed restoration, and community-based natural resource management have contributed to vegetation recovery, biodiversity conservation, and improved ecosystem services in several regions. Nevertheless, conservation outcomes remain constrained by limited institutional capacity, inadequate financing, weak policy implementation, and insufficient long-term monitoring. Significant research gaps persist in lowland ecosystems, wetlands, riparian habitats, climate change impacts, and ecosystem service assessments. Strengthening integrated landscape management, long-term ecological monitoring, and community-based conservation approaches is essential for sustaining Ethiopia’s biodiversity and ecosystem services.
