| Summary: | Javan Hawk-eagle (Spizaetus bartelsi) plays a considerable important role in the
ecosystem. With its endangered and protected status, every threat must be
maintained in order to prevent such a national symbol of Indonesia from
extinction. A major threat faced by the birds is destruction of their habitat due to
human encroachment and wildfire, especially in the Mount Ciremai National
Park. Substantially, understanding habitat degradation risk is crucial for
developing appropriate conservation strategies in future years.
This research was carried out on the basis of risk analysis through which the
susceptibility of the hazardous factors and the vulnerability of element at risk
were identified to estimate probable habitat degradation. Human encroachment
and wildfire hazard as well as habitat vulnerability were measured by means of
Spatial Multi Criteria Analysis. Hierarchical approach was utilized in order to
develop semi-quantitative modelling. This research introduces both social and
biophysical factors which were constructed from extensive study of previous
research and experts� opinion.
Land demand of subsistence farmers surrounding the national park was used as
the entry point. Altogether with distance and land cover factors, it was used to
measure human encroachment. Wildfire hazard was estimated from three aspect
of the famous �triangle of fire� i.e. fuel availability, ignition, and environmental
factor. Life requisites (foraging and breeding requirement) were used to portray
habitat vulnerability.
The result of this research revealed that 46.78% of the national park was
threatened by accumulative hazard of human encroachment and wildfire. In the
nutshells, only 454.12 ha (2.93%) and 3.860.35 ha (24.91%) of the area were all
breeding and foraging habitat requirement fulfilled respectively. Meanwhile,
38.54% of total national park area were risked in maximum threat. |
