Our current study was conducted in Zijje Maryam Church Forest, Ethiopia, to explore woody species composition, structure, regeneration status, and anthropogenic disturbances inside the sacred groves. The aforementioned information for adequate conservation and management of the church forest is not well documented. Fifteen main quadrats each having an area of 625 m (25 m × 25 m) were used for vegetation and disturbance data collection. Determination of the sampled quadrats was based on the principle that minimum quadrats give the smallest possible area in which all species occurring in the church forest are present. All woody species with a diameter at breast height (DBH) ≥ 2.5 cm within the quadrat were identified, counted, and their height and DBH data were recorded. The criterion to start at DBH ≥ 2.5 cm was to exclude seedlings having DBH < 2.5 cm and height ≤0.6 m. Sapling and seedling data were collected using 45 saplings and 45 seedling quadrat that measured 4 m and 1 m, respectively. Vegetation data analysis and ANOVA were used for statistical comparison. A total of 48 woody plant species belonging to 46 genera and 36 families were identified. was the dominant family containing 5 species followed by with 3 species. Total basal area of the church forest was 83.03 m ha. The density of seedlings, saplings, and matured woody species stem ha were 15555, 3833, and 865, respectively. Talking these densities, the regeneration status of the forest was good. The Shannon diversity and evenness of woody plant species in the forest was high, 3.29 and 0.85, respectively. 27.67 (9.22%) and were species with the highest IVI. Nearly, 22% of areas of the forest get disturbed and higher anthropogenic disturbances occurred near the edge of the forest. Gathering, clearing, and grazing are the major human disturbances that stakeholders need to tackle for conservation. Zijje Maryam Church Forest has heterogeneous species composition with varied seedlings and saplings. Therefore, local conservation policies recommended not only protect large forests, but also the small and valuable forests service to the needs of local people.
我们当前的研究在埃塞俄比亚的齐杰·玛丽亚教堂森林开展，旨在探究神圣树林内木本植物的物种组成、结构、更新状况以及人为干扰情况。关于教堂森林进行充分保护和管理所需的上述信息记录并不完善。我们使用了15个主要样方，每个样方面积为625平方米（25米×25米），用于收集植被和干扰数据。抽样样方的确定基于这样一个原则：最小样方要给出教堂森林中所有出现物种的最小可能面积。样方内所有胸径（DBH）≥2.5厘米的木本植物都被识别、计数，并记录其高度和胸径数据。以DBH≥2.5厘米为起始标准是为了排除胸径<2.5厘米且高度≤0.6米的幼苗。使用45个分别为4米和1米的幼树和幼苗样方收集幼树和幼苗数据。采用植被数据分析和方差分析进行统计比较。共识别出48种木本植物，分属46属36科。 是包含5个物种的优势科，其次是 有3个物种。教堂森林的总断面积为83.03平方米/公顷。每公顷幼苗、幼树和成熟木本植物茎的密度分别为15555、3833和865。综合这些密度来看，森林的更新状况良好。森林中木本植物物种的香农多样性和均匀度较高，分别为3.29和0.85。 27.67（9.22%）和 是重要值最高的物种。近22%的森林区域受到干扰，且森林边缘附近的人为干扰更为严重。采集、清理和放牧是利益相关者为保护工作需要应对的主要人为干扰因素。齐杰·玛丽亚教堂森林具有异质的物种组成，有不同的幼苗和幼树。因此，当地的保护政策建议不仅要保护大型森林，也要保护为满足当地人民需求而存在的小型且有价值的森林。
