Submontane forest is considered as one of the biodiversity hotspot. Scientific information on bird diversity in this forest, however are lacking. The aim of this research was to find out submontane forest bird diversity and its conservation management. The research was carried out in three forests areas at Bantimurung Bulusaraung National Park submontane forest. Point Count method was used to observe bird population. Data were analyzed using Shannon-Weiner diversity index, Pielou Evenness index, Simpson dominance index, Margalef species richness index, and Sorensen Similarity index. The significance different between the number of individual bird was tested using Kolmogorov-Smirnov test. The result showed that submontane forest at Bantimurung Bulusaraung National Park is rich in bird diversity, bird endemic species and protected bird species. There was a significant different on the number of individual bird at several human disturbance levels. Based on these conditions, it is important to enhance understanding of the local people regarding zonation and develop cooperation with many stakeholders to increase the local community awareness concerning forest conservation. It is also necessary to ensure the sustainability of the National Park's conservation program to maintain the submontane forest conservation.
