The study was conducted to determine woody plant species composition, structure, and regeneration status in Saleda Yohans Church forest, South Wollo Zone, Ethiopia. Five transect lines oriented to north-south directions at a distance of about 500 m were laid down along transects across the forest. Fifty main plots of 20 m × 20 m were laid for tree/shrub data collection. Within each main plot, 5 small quadrats of 5 m × 5 m were laid in the corners and centre for the collection of seedling and sapling data of woody species. All vegetation data within the plots were counted and recorded. Tree height and diameters at the breast height of plants were also measured and estimated. Moreover, frequency, basal area, diversity, evenness, and other vegetation data were analyzed. The result showed that this Church forest is composed of 50 woody plant species distributed in 31 families. The Shannon-Wiener diversity index and evenness values of the forest were found to be 3.82 and 0.84, respectively. was the dominant family followed by in their species composition. The density of trees/shrubs, saplings, and seedlings was 625, 650, and 935 ha, respectively. Based on the result, the entire vegetation of Saleda Yohans Church forest is in good regeneration status. In conclusion, although this Church forest appears to be in a good regeneration status, its species richness is low compared to a similar study of some other vegetation. Therefore, attention should be given to the rehabilitation of this forest.
本研究旨在确定埃塞俄比亚南沃洛州萨莱达约汉斯教堂森林中的木本植物物种组成、结构和更新状况。沿着森林设置了五条南北走向、间距约500米的样线。沿着样线设置了50个20米×20米的主样地，用于收集树木/灌木数据。在每个主样地的角落和中心设置5个5米×5米的小样方，用于收集木本物种的幼苗和幼树数据。对样地内的所有植被数据进行计数和记录。还测量和估算了植物的树高和胸径。此外，对频度、断面积、多样性、均匀度和其他植被数据进行了分析。结果表明，这片教堂森林由分布在31个科的50种木本植物组成。该森林的香农-威纳多样性指数和均匀度值分别为3.82和0.84。在物种组成方面， 是优势科，其次是 。树木/灌木、幼树和幼苗的密度分别为625、650和935株/公顷。根据结果，萨莱达约汉斯教堂森林的整个植被更新状况良好。总之，尽管这片教堂森林的更新状况似乎良好，但与其他一些植被的类似研究相比，其物种丰富度较低。因此，应关注这片森林的恢复。
