Abstract: The vegetation of Gambella national park varies in terms of composition and structure due to the occurrence of rivers bisect the park. Data of the vegetation was collected by different techniques such as field observation, GIS and remote sensing, GPS and compass, and topographic map. The scientific name, local name and their uses was identify by indigenous knowledge of the community, experts knowledge and field guide line book for each tree species. Stratification was used of homogeneity/heterogeneity of the land use of the park and make easy ways for study. There were also 80 sample plots with 10m x10m rectangular plot size was taken to carry out counting and identifying the species using transect line in the study area. A total of 39 species were recorded and the most dominance species was Grewia mollis. The analysis indicated that the riverine forest was dense (more stems) than terrestrials forest. The highest stem grown in the Riverine forest was Grewia mollis A. Juss whereas terrestrial species was Bridelias cleroneura and also more tree species were available in terrestrial wood land forest than riverine forest. As move to the reverine forest, there was more vegetation, abundance, distribution and greenness. Land use land cover change indicated that terrestrial wood land forest is decreasing from time to time due to anthropogenic factors. Therefore, in order to keep the sustainability of the national park from deforestation there must be integration of stack holder organization, awareness creation of the community, participatory approach in the park is required.
