Thus this study was conducted to evaluate the contribution of forests on the EiABC Campus and the College of Natural and Computationa Sciences at Addis Ababa University. Species diversity, Carbon stock potential, and Temperatureare the parameters used to assess the contribution of forests in the campuses. Data on the vegetation were collected using a purposive sampling technique. The forest composition revealeda total of 2,641 individual trees, representing 69 species from the all live woody trees that are found in the site under ≥ 5 cm (DBH). Diversity of plant species was examined using the Shannon-Weiner Index and evenness metrics, indicating high woody species diversity based one stablished standards. The population structure, analyzed through height and diameter class distributions, displayed an inverted J-shape, suggesting a stable population. Carbon stock analysis of the biomass was conducted using the general tropical dry forest biomass regressionequation. The results showed a total carbon stock of 92.14 t/ha and 151.60 t/ha for the two sites,with 76.78 t/ha and 15.36 t/ha in the above-ground and below-ground biomass, respectively, at EIABC, and 126.3 t/ha and 25.27 t/ha at the College of Natural and Computational Sciences. Temperature measurements taken inside and around the study sites revealed that the vegetation significantly reduced local temperatures. Overall, the results highlight the stability andproductivity of the forests. From the perspective of reducing the effects of climate change and protecting biodiversity, it is recommended that these forests be sustainably managed and protected to ensure ongoing carbon sequestration and biodiversity conservation.
