abstract = "Invasive alien species have been affected every ecosystem types on the planet and considered as the second greatest global threat to biodiversity, following habitat destruction. Cryptostegia grandiflora (Rubber vine) is one of the invasive alien species those posing negative impacts on country’s biodiversity.  Accordingly, this species has negative impact on native plant species by growing up into their canopy, blocking their access to the sun and “choking them. However, its impact on biodiversity has not been determined. Therefore, the objective of this study was to assess the impact of Cryptostegia grandiflora, on the species diversity and composition of invaded communities in East Shewa Zone. Accordingly, Systematic random sampling design was employed for data collection from 60 quadrants, each with 20 m x 20 m area at 50m intervals.  Out of 60, 40 plots were laid in Ledota natural forest and the remaining 20 quadrants were laid at the roadside. From the three sites, 37 plant species representing 19 families were recorded. Species diversity indexes (H’) were 1.88, 1.67, and 0.79 in un-invaded forest site, invaded forest and roadside respectively. Similarly, cover percentage of un-invaded forest site were exceeded invaded forest by 10.5% due to infestation of the invasive alien plants, C. grandifilora, has turned into a major driver of biodiversity loss in the invaded regions and adversely affecting agro-economy of the pastoralist and the country. Therefore, it needs the effort of all concerned bodies to control the impacts and its spread.",
