this thesis investigates the benefits and options for replacing declining urban ash trees, as well as the value-added potential of urban trees more broadly. the study aims to provide insights into the selection of suitable tree species for urban areas, considering their ecological, social and economic benefits. the research methodology involved a literature review of various peer-reviewed articles, government sites and books to assess the survival rate of different tree species and their growth patterns in urban areas. the study also analyzed the value-added potential of selected tree species in terms of ecosystem services, such as carbon sequestration, air quality improvement, and aesthetic value. the study also analyzed the approaches used by different cities to replace ash trees and suggested new species to plant. the findings indicate that urban trees have significant value-added potential, beyond their ecological benefits. the research suggests that a diverse mix of tree species should be considered in urban tree-planting programs to improve the resilience and sustainability of urban ecosystems. the results of this study can help urban planners, landscape architects, and policymakers to make informed decisions regarding the selection and management of tree species in urban areas.
