The study attempts to investigate the plant species diversity, their abundance and distribution in Haramaya University, Main Campus. An intensive inventory was made to collect the required data. Sample plot of size 10 × 10 m quadrant was used for this particular study. Fifteen quadrats of sample plot for two sites, one at Main Campus main gate (M) and site two, arboretum (A) were systematically laid down to collect the data. The study revealed that 34 different species were recorded in site one, 40 different plant species were recorded in site two, and 22 species were found in common in both sites, accounted about 76% of the species richness for the first site and 69% of the second site. Out of the 34 species recorded in the first site Lantana camara accounted 14.7% of the relative abundance followed by Thuja accidantalis, Podocarpes falcatus and Cupressus lussitanica accounting 11, 9.2 and 6.6% of the relative abundance, respectively. In second site, out of the 40 species, it is found that L.camara accounted for about 11.8% of the relative abundance followed by C.lussitanica, Phoenix reclinata and Juniperus procera accounting 11.4, 6.9 and 6.3%, respectively. Shannon diversity index indicates that plot two (A) is more diverse (H=3.26) than plot one (M) (H=2.97).The Simpson index of site one and site two are 0.063 and 0.05, respectively. Generally, it is possible to conclude that the university has various plants species having different habitats of tree (T) and shrubs (S).

Key words: Plant species diversity, Plant abundances, Plant distribution and Haramaya University.
