Abstract

The Flores hawk-eagle (Nisaetus floris) is an endangered raptor endemic to the Lesser Sunda region and remains understudied, hindering effective conservation planning. This study investigates the species’ home range, habitat use, and threats at two active nesting sites in Ende District, Flores Island. Home range estimates varied between 8.439 km² (using minimum convex polygon/MCP) and 23.38 km² (using hypothetical-circular home range/HCHR) in Wolojita and from 6.385 km² (MCP) to 23.38 km² (HCHR) in Mbuli. Intensive use areas were relatively small, measuring 0.449 km² in Wolojita and 0.494 km² in Mbuli. Habitat use analysis revealed that in Wolojita, the eagles favored secondary forests, settlements, and shrublands, while in Mbuli, they primarily utilized grasslands and secondary forests, actively avoiding agricultural lands, rice fields, and areas near sulfuric rivers. Secondary forests appear to provide essential resources such as nesting trees and prey availability. However, competition with other raptor species, coupled with anthropogenic threats such as habitat degradation, land-use change, and persecution driven by livestock predation, poses significant risks to the species’ survival. Conservation should focus on preserving secondary forests, promoting sustainable land-use practices, and mitigating human-wildlife conflict to ensure the long-term viability of the population.

Abstract

Wildlife conservation is fundamental to mitigating the extinction due to wildlife trade. Thus, various conservation policies have been used as a reference: IUCN, CITES, and Government Policy P.106 of 2018. This research aims to record Facebook-based wildlife trade, identify the traded wildlife conservation status, and estimate the selling price. Data was taken since the group was formed until 1 July 2023. The results reveal that 107 species belonging to 53 families were recorded in 31 trading groups, comprising 82 species of aves, 17 species of herpetofauna, and eight species of mammals. Among those traded wildlife, based on P.106, 80 species are unprotected, while 27 are protected. Based on the IUCN, most traded wildlife is categorized as LC with 77 species. Some species are categorized as CR with four species, EN with 9, VU with 8, NT with 8, and NE with one species. Referring to CITES, 73 species classified as non-appendices dominate the trading groups, followed by 24 species of Appendix II, 9 of Appendix I, and 1 of Appendix III. The estimated selling price of all traded wildlife is approximately IDR 317,125,000. Governments and other conservation bodies must pay more attention to the growing Facebook-based wildlife trade, especially for protected and endangered species.
