Tree and Bird Species Diversity in Several Urban Forest Area of Bandar Lampung City

This study investigated the inter-relationshep between diversity of tree and bird species existed in urban forest of Bandar Lampung City. The objectives of the study on Tree and Bird Species Diversity in Several Urban Forest Area of Bandar Lampung City are to know a) tree species diversity composition in urban forest vegetation, b) bird species diversity, and c) the correlation between those both components. The study conducted on six areas of urban forest in Bandar Lampung City. Tree sampling was measured within plot line having 20 m x 20 m size, while bird observation was done using direct watching method which was performed every morning (06.00 similar to 08.00) and evening (16.00 similar to 18.00) during tree days for each urban forest area. The biodiversity parameters used in this study are Margalef Species Richness Index, Shannon Biodiversity Index, and Modified Hill's Ratio Index of Evenness. In all urban forest areas of Bandar Lampung City was identified 45 tree species (24 families) with index of species richness 6.22, index of species diversity 2.92, and index of evenness 0.60. Compared to closest natural vegetation (of Wan Abdul Rachman Provincial Park) the vegetation is very different (index of similarity 0.13). The study concluded that a) urban forest vegetation of Bandar Lampung City are generally dominated by domesticated species, 2) 24 birds species (16 families) were identified in all of urban forest area of Bandar Lampung City, and c) there is positive correlation between the tree species diversity and bird species diversity in urban forest of Bandar Lampung City.
