Abstract
In this study, we tested whether urban landscape structure influences avian species diversity using data for Harare, Zimbabwe. Initially, we quantified landscape structure using fragmentation indices derived from a 5m resolution SPOT 5 imagery. We collected bird species data through field-based observations of birds at 35 locations occurring in five land use/land cover types. We quantified avian species diversity using Barger-Parker, Menhinick and Simpson’s Indices. Regression analysis was used to determine the nature and strength of the relationships between avian species diversity and fragmentation indices. Results indicated that woodland specialist avian species are negatively associated with landscape fragmentation, while grassland specialist and generalist avian species positively responded to patch edge density, habitat patch size and shape complexity. Overall, our results suggest that changes in landscape structure due to expansion of built-up areas in tropical urban areas may influence avian species diversity.
