Abstract: Tree species diversity in urban green spaces supports the provision of a wide range of urban ecosystem services, well studied in developed countries and less so in developing countries, where little is discussed concerning the role of urban communities in addressing the eminent threat facing green spaces. A study was, therefore, conducted to assess the impact of community involvement in the management of urban green spaces, which is mostly left in the hands of the central government in most developing countries. Two hills, namely, Sadzi and Chiperoni hills, were selected within Zomba city, where the latter has no community involvement in managing it. Trees with diameters at breast height (DBH) of ≥5 cm were measured and identified to species level from 25 sampled plots (20 × 20 m each). The results found a total of 51 species, 40 genera and 17 families, with the Fabaceae family dominant in both hills. A Shannon index of above 3.0 was recorded from both hills, with a greater tree density for Sadzi hill at 695 trees/ha. Sadzi hill has gained more than a twofold increase in green cover, while Chiperoni has lost 10%. Despite being in the regenerating phase, the community management is contributing to urban green space provision, ecosystem services and biodiversity conservation.
