Soil microbiome in urban areas is continuously shaped by urbanization and associated processes like native plant species removal, type of vegetation (native and exotic), soil physicochemical properties and anthropogenic activities, and the introduction of invasive plants, etc. Subsequently, above-ground vegetation is shaped by the soil microbiome. However, such information is hardly included while selecting plant species for greening efforts or plantation within green spaces. This could be due to a lack of studies connecting above-ground vegetation and soil microbial communities. In particular, the number of studies investigating soil microbiota and its effects on aboveground vegetation are limited in India. Existing studies vary in research questions, methodologies, urban green spaces explored, microbial community aspects, and soil characteristics examined. In this study, we are conducting a systematic evidence mapping to consolidate this research and identify global trends and gaps. We focus on the effect of above-ground vegetation on the soil microbiome in urban green spaces. Using an exhaustive search string, we retrieved 598 papers in total from two databases (Web of Science and SCOPUS) and one search engine (Google Scholar). By focusing on these relationships, we provide insights for planning and maintaining urban green spaces. This evidence mapping contributes to the scientific understanding of such spaces and offers practical guidance for rapidly urbanizing countries, emphasizing the integration of soil microbial communities in designing and restoring urban green spaces across different geographical locations.
