Abstract:
Woody species in Coffee forestland plays significant indicator for woody plant species
investigation. The study conducted to investigate woody species richness, diversity and
evenness on Coffee forestland in Dhidhesa district of Buno Bedele zone Oromia
regional State. The study cover three-selected kebele (Geshe, Garado, and Gepha)
based on the presence of coffee forests, aimed to asses’ woody plant species richness
and diversity in coffee forest of Dhidhesa district. It used as reference or clue for
farther investigation and contribute to raising public awareness on the value of the
woody plant species in the coffee farm field. Purposively three-study kebele selected and
Systematic random sampling applied to locate sample quadrat. Systematically Sample
quadrat taken from land uses of coffee plantation. Ten sample quadrat from each kebele
of coffee plantation land uses was laid at about 100 meters’ distance interval from each
other. Along the transect lines, Ten sample quadrat measuring 20 m × 20 m (400 m2)
were laid down at 100 m interval from each other and total sample was 30 quadrats
with (1200 m2 ) in coffee farm field. A total of 22 trees species belonging to 16 plant
families were recorded on the Coffee forest land at study sites. In the study area, the
frequency of woody species occurrence on coffee forest recorded. Croton
macrostachyus, Cordia africana, Albizia gummifera, Olea africana, Syzygium
guineense and Podocarpus falcatus were among the most frequent tree. The results of
this study have shown that woody species inventory on coffee forest provided baseline
information on existing situation of woody species richness, diversity, evenness,
frequency, and basal area. To assess the diversity of woody species on coffee forest
across the study sites. In this study, general conclusion was present based on the woody
plant species diversity survey of observation in the study area. Raising the amount of
woody species diversity in Coffee forest at the study area and encourage awareness of
local people in diversifying, conserving and sustainability using of woody plant species
of coffee forest should be cared out. Finally, the present study is limited to woody plant
species richness, diversity and evenness then further studies on environmental
parameters, forest management, land use management system, conservation system, on
woody plant species.
