Preliminary findings: Woody plant diversity in cultural landscapes of southwestern Ethiopia

By Girma Shumi and colleagues

The following is the first of a series of upcoming summaries of preliminary findings from our ERC funded research. Details are subject to change.

Maintaining biodiversity is a global challenge. Some scientists have argued for strictly protected forest areas, while others have suggested that farmland also can have conservation value. To assess the conservation value of farmland and forest for woody species diversity in southwestern Ethiopia, we investigated six kebeles in Jimma Zone. We identified woody plant species in 78 randomly selected 20 m x 20 m sample plots in forest and homegardens; and in 72 randomly selected 1 ha sites in arable land and pastures. We found 96 and 122 plant species in forest and farmland, respectively. In forest, woody plant composition was affected by coffee management practices, current and historical distance to farmland, and the effort required by local people to reach a given site (so-called “cost distance”). Mean species richness ranged from 13 at the forest edge to…
