A total of sixty-six (30m X 30m) plots were established every 100 m interval along altitudinal gradient (2811-3073 m a.s.l.) in five transect lines for vegetation and environmental data collection. The forest is floristically rich with 125 species, with more than 14% endemic to Ethiopia, and Eritrea. The species composition is dominated by herbs and shrubs.  Occurrence Endemic species · Environmental gradient Floristic composition Kibate Forest Population structure Wonchi GBIF Dataset Type Vocabulary: http://rs.gbif.org/vocabulary/gbif/dataset_type_2015-07-10.xml Observation GBIF Dataset Subtype Vocabulary: http://rs.gbif.org/vocabulary/gbif/dataset_subtype.xml This work is licensed under a Creative Commons Attribution (CC-BY 4.0) License.

Wonchi is found in the southwest Shewa Zone of Oromia Regional State. Kibate Forest is a small forest patch that covers 450.2 ha, situated in the Gibe watershed of the Shewa floristic region at 8° 46′ 30.1908′’‒8° 47′ 36.7584′’ N and 37° 51′ 53.8524′’‒37° 54′ 19.0152′’ E. Altitudes range between 2800 and 3387 m a.s.l. The vegetation type is dry evergreen montane forest, widely intersected by areas of cultivation (Friis et al. 2010). -180 180 90 -90 2017-12-01 2018-01-01 unknown Hanny Lidetu Solomon Addis Ababa University Data Steward

The study was conducted in Kibate Forest, Wonchi Southwestern Ethiopia. A reconnaissance survey was carried out in the Kibate Forest from December 2017 to January 2018 to collect information on the accessibility of sites and to determine sampling methods. Following the reconnaissance survey, five transect lines were laid out systematically along the edges of Wonchi Crater Lake, forest track/road, two small forest valleys with streams, and along the Walga stream. For the systematic sample of the five transects, the altitudinal ranges (2800‒3100 m a.s.l.) were divided into three classes with a 100 m a.s.l. interval, point position recorded using Gramin GPS 72 with an accuracy of 5 to 10 m under normal conditions, extending within 15 m under the dense forest canopy. Similarly, slopes (20‒70%) of each plot were recorded using a clinometer (percent scale). Vegetation and environmental data collection began at the lower edge of the forest and continued to the heights along the altitudinal gradient in all transects to include the representative floristic composition in each elevation class. Sixty-six 30 m × 30 m plots were established every 100 m. The number of plots in each elevation class was determined by the length of transect and varied from nine plots, (following the small stream in the middle of the forest), to 18 (along the bank of the Walga stream). In each plot, cover-abundance percentages were estimated for all vascular plant species following the Braun-Blanquet scale and then converted by van der Maarel ordinal transformation (van der Maarel 1979). For population structure analysis, diameter at breast height (DBH) of each woody species with DBH ≥ 2.5 cm and height ≥ 2.5 m were recorded (Woldu et al. 1999) using a diameter tape and Suunto clinometers, respectively. Woody species with DBH ≤ 2.5 cm were counted. Vascular plant specimens were collected with the help of local guides, pressed, dried, and brought to the National Herbarium of Ethiopia (ETH) at Addis Ababa University. They were then identified as per herbarium procedures, confirmed by a taxonomic expert, and deposited at the ETH. In addition, the status of endemic species and their distribution in the flora were cross-checked with previous research (Vivero et al. 2006; Hedberg et al. 2009; Meragiaw et al. 2016; IUCN 2019). Altitude and geographic coordinates were recorded for each of the 66 plots using GPS. In addition, ecological disturbances such as grazing intensity and human disturbances (felling of trees for firewood, charcoal production, and burning of vegetation for expansion of agricultural land) were noted, based on visual inspection. The status of human interference was estimated through the etic or crosscultural approach following Hadera (2000), and subjective scales were designated as 0 = nil; 1 = low; 2 = moderate, and 3 = heavy. Similarly, intensity of livestock grazing was estimated following Woldu and Backeus (1991) as 0 = nil, 1 = slight, 2 = moderate, 3 = heavy, and 4 = destructive. Veronika Johansson pointOfContact Biodiversity is crucial for maintaining a healthy environment, ensuring food security, and building resilience, especially in developing countries such as Ethiopia. Rich in biodiversity and traditional farming systems, Ethiopia hosts the Eastern Afromontane biodiversity hotspot as well as the Horn of Africa biodiversity hotspot, which are critical for the Arabica coffee wild gene pool, but one of the least developed globally. Conserving biodiversity in Ethiopia requires robust evidence, skills, and policies, and quality data production and effective mobilization to data aggregators like GBIF are essential. The biodiversity data in Ethiopia is available in fragmented forms across various institutions, limiting access, especially for policymakers and practitioners. This bottleneck is largely due to the need for skills in developing and managing databases and making data available in an integrated manner at national, regional, and global scales. In addition, there is a shortage of analytical skills in producing quality scientific data and knowledge. This project aims to extend the work initiated in 2017 by the EU-funded GBIF Biodiversity Information for Development project BIDERSE and to address challenges by providing capacity-building training and knowledge transfer, enabling stakeholders to mobilize, manage, and use data according to global best practices. The key stakeholders identified for establishing a national biodiversity platform will act as a basis for this initiative. 2025-07-28T11:20:03.086+00:00 dataset Misganaw M (2025).
