The diversity of bird species based on the altitude of the protected forest area in Sirimau Mountain in Soya Village - Ambon City

Abstract

This study is aimed to discover the diversity of bird species based on the altitude of the area and to discover the impact of vegetation as habitat towards the diversity of bird species in protected forest area in Sirimau Mountain in Soya Village located in Ambon City. The method used to discover the diversity of birds was the IPA-method (Indices Ponctuels d’Abondance) while observing the vegetation used the CSS-method (Continous Strip Sampling) alongside the observation paths. The protected forest consists of three area of different altitudes, namely 300 meters above sea level (masl), 400 masl and 500 masl. The bird species found in the protected forest area in Sirimau Mountain in Soya Village as a whole were 16 species. The forest area at 300 masl was found 14 bird species with diversity index (H’) of 2.57, the forest area at 400 masl was found 12 bird species with diversity index (H’) of 2.42, while the forest area at 500 masl was found 11 bird species with diversity index (H’) of 2.10. There were 8 bird species found in every area of three different altitudes that were dominant such as Perling Ungu (Aplonis motalica), Walet Sapi (Collocalia esculenta), Perkicit Pelangi (Trichoglossus haematodus), Pergam Laut (Ducula bicolor), Sesap Madu Sriganti (Nectarinia jugularis), Srigunting Lencana (Dicrucus bracteatus), Nuri Pipi Merah (Geoffreyus geoffreyi) and Tekukur Biasa (Streptopelia hinensis). Meanwhile, the dominant types of vegetation found in the area were Damar (Agathis sp.), Kayu Merah (Eugenia jambolana) and Meranti (Shorea sp.)
