The aim of the study w.s to compare glade and forest-glade edge plant community attributes for man-made, upper and low.r natural glades. Tw. plots w.re set up in tw.lve glades at 2.5, 12.5 m and three plots in thirteen glades at 2.5, 12.5 and 22.5 m depending on the size of the glade. The results show.d that plants total abundance, percentage basal cover, species richness and species diversity for upper and low.r natural glades differed significantly p w.re highest at the forest-glade edge and decreased tow.rds the glade interior. Plant species composition of the three glades types differed significantly (MRPP: T = -4.51, p w.s highly significant p w.ile for forbs species richness and diversity w.re significant P w.r natural glades grasses and forbs’ total abundance, species richness and species diversity differed significantly p w.h forms in the low.r natural glades w.re associated w.th the forest-glade edge or glade interior χ2 = 15.95, df = 4, p Eleusine jaegeri, Heterogon contortus, Senna mimisoides, Digitaria scalarum, Clutia abyssinica) w.re habitat indicators for disturbed areas, w.t humid grey/black clay soils for upper natural glades and three (Solanum incanum, Senna didymobotrya, and Pennistem mezianum, w.re indicators of overgrazed areas and black clay soils for man-made glades. In conclusion, plant species abundance, richness and diversity w.re highest at the forest-glade edge and decreased tow.rds the glade interior, w.ile plant species composition differed significantly betw.en the three-glade types.
