摘要:Raptors are indicators of biodiversity, environmental health and habitat quality because of their sensitivity to human disturbance and environmental contamination. Nest site selection can have important nesting success consequences in raptors. In relation to this, a spatial analysis was undertaken to assess the relationship between landscape structure and the presence of predator nests in the human-modified landscape of Panaruban and Telaga Warna, West Java, Indonesia. The methods used in the study were qualitative (descriptive analysis) and quantitative (using Fragstats v.2.0). The study employed four circular buffers at distances of 250, 500, 750 and 1000m around each nest tree in order to analyse the relationship between raptor nest occurance and landscape structure. The results showed that the landscape of Panaruban and Telaga Warna is a mosaic consisting of natural and artificial vegetation of different structures. The four species of raptors identified were the Javan hawk eagle (Spizaetus bartelsi), the changeable hawk eagle (Spizaetus. cirrhatus), the crested serpent eagle (Spilornis cheela) and the Indian black eagle (Ictinaetus malayensis), which tend to select nesting sites that have alow degree of landscape contrast for a distance of 250m around the nest. In terms of landscape complexity, however, there were no great differences among the nesting sites at a distance of 250m. The edge density around the Indian black eagle nest was higher than for the other nests at distance of 250–1000m. Characteristic differences in nest site selection may be due to landscape structure at different scales around the nest. Certain management strategies should be undertaken, step by step, in order to maintain the sustainability of the raptor population and, at the same time, contribute positively to the local people living in the human-modified landscape in Panaruban and Telaga Warna.
