This Research Report reviews the provision of four ecosystem services by 18 small and medium stature tree species using the i-Tree Eco model and compares the performance of these trees in different age groups. It is the second of two Reports reviewing ecosystem service provision by trees of different stature and age in urban areas. The first Research Report reviews the ecosystem provision of large stature trees. Collectively, these Research Reports will be useful to those engaged in urban forestry management by helping to identify which tree species may be favoured for the delivery of particular ecosystem services through selective planting. Both Reports are summarised by an overarching Research Note.
