This study is about woody plant diversity and structure of Saleda Yohans Church forest in Amhara Sayint District, South Wollo Zone, Ethiopia. The objectives was quantitative analysis of floristic composition, vegetation structure and regeneration status of woody species. A preliminary survey was done to determine sampling method and identify sampling site of the forest. Sampling technique was used for vegetation data collection. Five transects lines oriented to north - south directions at a distance of about 500 m were laid down along transects across the forest. Fifty (50) main plots of 20 × 20m within each five small quadrats of 5 x 5m were laid in the corners and centre. In each main quadrat, all tree/shrub and saplings and seedlings of woody species within the subplots were counted and recorded. Tree height and diameters at breast height of plants were also measured and estimated using a meter-stick so as to categorize plants into height category corresponding to seedling, sapling and mature individuals. Moreover, frequency, basal area and diversity evenness, etc were derived from the vegetation data. Results of the study showed that the Church forest is composed of 50 woody plant species distributed in 31 families. The Shannon Weiner diversity index and evenness values of the forest were found to be 3.82 and 0.84, respectively. Lamiaceae was the dominant family followed by Fabaceae. Tree/shrub, sapling and seedling individuals were 1250, 1300 and 1870respectively. Based on height classification, the entire vegetation of Saleda Yohans Church forest is in a good regeneration status. In conclusion, although Saleda Yohans Church forest appears to be in a good regeneration status, its species richness is low compared to some other vegetation of similar study. Therefore, especial attention should be given for it rehabilitation.
