Floristic Composition, Vegetation Structure, and Regeneration Status of Woody Plant Species of Oda Forest of Humbo Carbon Project, Wolaita, Ethiopia

Our current study was conducted in Oda forest to explore floristic composition, vegetation structure, and regeneration of woody species in a newly established Humbo Carbon Project. In the project, the above information for sufficient conservation and management of the forest is not well documented. Data were collected in October and December 2014. Thirty-two quadrats (20 m × 20 m) lying 100 m far apart were used for shrub and tree data. In each major plot, subplots (1 m2) were established at the center and corner for seedlings and saplings data. Altitude, slope, and aspect were measured using GPS and clinometers. DBH, basal area, and IVI were used for vegetation structure. Among 62 species confined in 32 families and 54 genera, Dodonaea angustifolia and Combretum molle were the densest and the most dominant and frequent species with higher IVI. Altitude and slope had significant effect (p
