This research project aims to monitor and conserve the vertebrate diversity in Mindanao LTER sites.
Specifically it aims:
1. To monitor composition, richness and distribution of vertebrates species;
2. To assess conservation status, richness and distribution of vertebrate species; STUDY SITES
Mt. Musuan: Musuan, Maramag, Bukidnon STUDY SITES
Mt. Hamiguitan: Tumalite, San Isidro, Davao Oriental WORLD HERITAGE SITE STUDY SITES

• ConsiderIng that one of the biggest vertebrate group (birds) was undersurveyed, the richness of vertebrates across LTER sites was still high.
• The species composition and richness of vertebrates has low similarity percentage from each sites, IndicatINg high percentage of composition’s uniqueness.
• The high species richness of reptiles in Mt. Hamiguitan is a result of more suitable temperature and the availability of unpolluted water bodies. • Sudden declIne of H. cInnamomea and P. jagori was associated to its temporal distribution
• Endemism was relatively high on mammals (59%) and average in birds (49%) and reptiles (46%).
• Absence of the three threatened species that were observed before ; and the new threatened species noted in the current study indicates the need to strengthen protection and conservation efforts. Acknowledgment
