“…4 ) this agrees with Tekle and Maryo [ 18 ] that show that human influences, such as grazing, decreased significantly as altitude increased. Similar research findings in Ethiopian Afromontane forests confirmed the importance of altitude as a major determinant of vegetation distribution along altitudinal gradients [ 12 , 19 , 57 ]. According to Lenoir, et al [ 58 ], changes in species distribution are associated with altitudinal range.…”

“…Gebeyehu, et al [ 59 ] also show the grazing effect on plant composition in the Awi zone in Northwest Ethiopia. Dibaba andSoromessa [ 19 ], and Bussmann [ 60 ] assured that disturbance affects plant community distribution by impeding natural regeneration and seedling establishment in tropical forests. And in general, altitude, aspect, slope, and grazing have a significant effect (Table 7 ) on the study area’s forest patch composition and community formation and this is also supported by other studies [ 11 – 14 ].…”

“…Furthermore, information on tree species composition and diversity is critical not only for understanding the structure of a forest community, but also for planning and implementing conservation strategies for the community [ 17 ]. Various studies on plant ecology have been conducted in Ethiopia to examine the distribution of plant community types in relation to environmental factors [ 12 , 19 ]. However, there are limitations to research on the relationships between environmental factors, plant species distribution, and community types in the Gozamin district of Northwestern Ethiopia.…”

Ethiopia is a mountainous country with great geographic diversity. The diversified topographic features in Ethiopia made the country have a rich biodiversity forest cover in tropical Africa. This made Ethiopia have the largest floral diversity in tropical Africa. This floral diversity is rich in endemic elements. About 6,027 vascular plant species (including subspecies) with about 10.7% endemism have been documented. Plant community types are primarily influenced by topographic factors, as well as disturbance and environmental factors. The objective of this study is to demonstrate that 1: The forest patches in the study area exhibit distinct plant community types. 2: The composition and structure of these plant communities are influenced by various environmental variables. To achieve this, a total of 76 plots were used to collect vegetation and environmental data. The collected data were then analyzed using the R software, employing agglomerative hierarchical cluster analysis and redundancy analysis (RDA) to identify plant communities and assess the relationship between these communities and environmental variables.R software was used to identify plant communities and analyze the relationship between plant community types and environmental variables using agglomerative hierarchical cluster analysis and redundancy analysis (RDA). Four plant community types were identified. The RDA results highlighted the significant impact (p < 0.005) of altitude, aspect, slope, grazing, and human interference on species distribution and the formation of plant communities. The RDA results highlighted the significant impact (p < 0.005) of altitude, aspect, slope, grazing, and human interference on species distribution and the formation of plant communities.The findings indicate that the variation in plant communities is closely associated with topographic factors such as altitude, slope, aspect, as well as disturbance factors like grazing, and human interference, with altitude being the most influential factor. Based on these findings, it is recommended that conservation plans take into consideration the effects of grazing and human interference in order to address the challenges faced in conserving forest patches in the future.Additionally, further research efforts should focus on mitigating disturbance factors and understanding the environmental variables that affect forest patches to enhance their conservation.

“…The investigation of the vegetation ecological status in the Chengcun Bay surrounding areas was carried out by the technical route of combining a shoreline survey with a quadrat survey [ 20 ]. According to the topography, accessibility and vegetation distribution of the project area, the survey shorelines and survey areas were determined ( Figure 2 ).…”

In recent years, global warming and sea level rise have further aggravated the risk of coastal erosion. Coastal vegetation plays an important role in resisting storm surges and alleviating coastal erosion. Therefore, screening plant species for the purpose of constructing ecological seawalls to protect or repair damaged coastal zones has become a hot issue. In this paper, a field survey was conducted to investigate the vegetation in Chengcun Bay surrounding areas of Yangjiang City by combining a line survey and sample plot survey. By understanding the vegetation types, distribution and community structure in the bay’s surrounding areas and analyzing the restricting environmental factors of those plants, we put forward some countermeasures for coastal vegetation restoration in difficult site conditions from the aspects of plant species selection, vegetation configuration and restoration technology, so as to provide reference for ecological vegetation restoration in similar locations.

“…The identification and analysis of species assemblages is the primary goal of plant community ecology (Dibaba, Soromessa, & Warkineh, 2022;Omijeh, 2020). In an effort to give a structural description of vegetation, Dansereau (1951) developed the structural approach to vegetation studies that leads to numerous researches on vegetation's structure changes with time.…”

The study examined the structural characteristics of shrub-tree species in Nangere, Yobe State, Northeastern Nigeria. Ten sampling point of quadrant size 200 by 100 meters were considered and five quadrants were randomly selected for the sampling using table of random number. Plant physical parameters such as the height, crown cover, diameter breast height (DBH), the volume of the tree and girth of the tree were measured on the field. The data obtained from the field were subjected to statistical analysis using correlation coefficient. The volume of tree is considered to be dependent variable height; girth, crown cover and diameter at breast (DBH) were considered to be independent variables. From the result, the height of the trees ranges from 3.25 m to 17.71 m, the girth 0.39 m to 8.00 m, the crown cover 1.20 m to 30.20 m, DBH 0.32 m to 7.20 m and the volume of the trees ranges from 2.06 m3 to 215.03 m3 . The result of the analyses revealed that there is a strong and positive correlation between the height of the trees and volume of the trees, the girth and volume of the trees, the crown cover and volume of the trees as well as the DBH and volume of the trees. The joint contributions of the four parameters (height, girth, crown cover and DBH of the trees) on the volume of the trees in the study area shows that R2 obtained for quadrant one, three, four and five are 0.99, 0.64, 1 and 1.00 respectively implying that the combined contribution of the parameters to the volume of trees in the study area was very high.
