Freshwater fish diversity and assemblage patterns in reforested streams of the Forest Research Institute Malaysia

A study of reforested streams within the Forest Research Institute Malaysia revealed that urban forest landscapes can support diverse freshwater fish assemblages, with species composition and ecological stability varying significantly among streams. The conservation-buffered stream exhibited the highest diversity (H′=1.582), while a recreationally impacted stream showed lower evenness and dominance by opportunistic species. Environmental factors, including water quality and habitat complexity, played a limited but notable role in shaping assemblage structure. These findings underscore the potential for urban forests to contribute to biodiversity conservation, even amid human influence.
