Penggunaan Habitat oleh Elang Brontok, Elang Ular Bido dan Elang Laut Perut Putih di Taman Wisata Alam Danau Buyan-Danau Tamblingan dan Sekitarnya

Research on the habitat preferrence by Changeable hawk-eagle (Nisaetus cirrhatus) (CHE), Crested serpent-eagle (Spilornis cheela) (CSE), and White bellied sea-eagle (Haliaeetus leucogaster) (WSE) was conducted at Nature Recreation Park of Lake Buyan and Lake Tamblingan and Surrounding area between February and July, 2016. Data collection was conducted through field observation using the “look down method” and the “look up method” combined with placement of observation points. Data collection was analysed by principle component analisys (PCA) method. Research results related to preferenced habitat were as follows: (1) the CHE prefered fragmented forest, secondary forest, and cultivated forest types habitat. (2) The CSE prefered habitat types of farming land, residence, and sosial forest. (3) The WSE prefered just one habitat type, that was the wet land habitat type.

Effects of landscape, habitat and fire and the distribution of the white-footed dunnart Sminthopsis leucopus (Marsupialia: Dasyuridae) in the Eastern Otways, Victoria.

Conservation and planning for threatened species requires knowledge of the species? spatial distribution, prefered habitat and response to disturbance factors such as fire. The white-footed dunnart (Sminthopsis leucopus) is currently listed as ?Vulnerable? due to its patchy distribution, the low density of populations and extinction threats. Studies of the species have been limited, and the aims of this study were to investigate the spatial distribution with relationship to landscape, habitat and fire factors. The study was undertaken in the Eastern Otway Ranges, southern Victoria where the species was recorded at 42 sites (44% of survey sites). The sites were all located within 10 km of the coast, and located in vegetation ranging from sclerophyll communities (forest, woodland and heathland) to coastal shrublands dominated by sedges and grasses. Logistic regression models were generated for species occurrence and predictor variables. The most parsimonious model was selected and although there was an association between presence of S. leucopus with landsystem and altitude, support for the models was not strong. The relationship with altitude was negative, indicating a preference for lower elevations. Models developed for other fauna species have identified landscape variables as being strongly predictive of occurrence, indicating that variables other than those investigated may be more suitable in predicting occurrence of S. leucopus at a landscape level. S. leucopus was recorded at a high percentage of sites 6-15 years post-fire age, and at maximal relative abundance at 4-9 years, providing evidence that it prefers mid succession habitats.
