Karimunjawa sebagai salah satu taman nasional yang memiliki berbagai macam tipe habitat dengan tingginya keragaman jenis burung yang ada. Penelitian kesamaan keragaman jenis burung telah dilakukan di area di hutan Legon Lele, Nyamplungan,kawasan pemukiman pedesaan Karimunjawa dan Legon Lele, kawasan kolam Cikemas dan Jatikerep, dan kawasan pantai Terusan, semua pendataan tersebut di lakukan di bulan Agustus 2009. Menggunakan metode titik telah terdata ada39 jenis burung ditemukan dikawasan tersebut. Indeks keragaman jens Shanon untuk masing-masing lokasi seperti pemukiman Legon Lele (H’=2.33), pantai Terusan (H’=2.31), kolam Jatikerep (H’=2.28), kolam Cikemas (H’=2.07), hutan Legon Lele (H’=1.81), pemukiman Karimunjawa (H’=1.75), dan hutan Nyamplungan (H’=1.65).

According to the previous researches, there are about 115 bird species in Karimunjawa Archipelago National Park area (Department of Forestry 2007). Karimunjawa island has many types of habitat such as settlements, forests, fish- ponds, and coastal area. Each habitat has unique characteristics and high diversity of bird species. Research in bird community structure of a habitat is important to do because birds have important role as bioindicator in environmental changes. In addition, the presence of bird species is determined by the presence of particular plant species as food resource, nesting area, and refuge area (Ewusie 1990). Therefore, the community structure of bird species in an area can describe the whole condition of that community. The purpose of this study was to analyze the bird community structure including the composition, abundance, and species di- versity. By analyzing the bird community structure, the indicator species from an area can be identified. Hence, the result of this study can be an evaluation data for sustainability management of Karimunjawa National Park. MATERIALS AND METHODS The research site was located in
