Both forest fragmentation and coffee cultivation negatively affect epiphytic orchid diversity in Ethiopian moist evergreen Afromontane forests

► Moist forest in SW Ethiopia is fragmented and managed for coffee cultivation. ► Forest management and fragmentation affect epiphytic orchid diversity. ► Concomitant shifts in epiphytic orchid community composition occur. ► Endangered orchid species occur both in small, managed and large, natural forest. ► Protection of pristine habitat remains essential for biodiversity conservation.
