Urban forest patches provide numerous environmental benefits. Diyagama forest (8.9 ha) is the only forest patch in the suburbs of Homagama which is left aside after recent infrastructure developments. For the first time we describe its biodiversity with special emphasis on floristics. The biological richness included 96 plant species belonging to 51 families and 87 genera of which 12.6% were threatened (8 vulnerable and 3 endangered). Only 12 were exotic species. The macro fungal richness was 48. Among the 72 bird species, 5 were threatened species (with 2 critically endangered). Out of 29 reptile species one species was in the threatened category. Amphibian richness included 7 species, while richness of fish species was 15 with 4 being threatened. Butterfly diversity was notable with 52 species, 3 of which are threatened. The site hosts 16 mammal species, including 5 threatened species.
As a biologically wealthy forest patch at mid-successional stage of regeneration, its conservation efforts should focus on controlling the spread of invasive species, prevention of road kills of fauna, protecting the remaining large trees against illegal exploitation and promoting natural regeneration with least disturbance in order to maximize its ecosystem services.
