Abstract

Javan hawk-eagle (Nisaetus bartelsi) is an endemic raptor species which has limited distribution area in Java Island. Their existence is threatened (endangered) due to their small population, habitat degradation as well as fragmentation. Gunung Halimun Salak National Park (GHSNP) is known for having the highest population of javan hawk-eagle. We conducted habitat suitability modeling of javan hawk-eagle in the GHSNP using principal component analysis (PCA) scoring method with 10 habitat variables, i.e.: altitude, slope, aspect, forest canopy density (FCD), temperature, rainfall, river distribution, road distribution, settlement distribution and population density. The results of this study showed that from total study area, 94,43% of high suitable habitat for javan hawk-eagle contained in GHSNP area. It means that the GHSNP is very important area for the existence and the conservation of the javan hawk-eagle population.The highly suitable class of javan hawk-eagle habitat is distributed on the areas with an average value for each habitat variable as follows: 68,96±11,18% (for FCD), 3.883,05±299,61 mm/year (rainfall), 19,93±1,72 ºC (temperature), 1.136,05±271,46 masl (altitude), 2.207,69±1.445,86 m (distance from road), 2.727,51±1.554,61 m (distance from settlement) and 3.829,08±1.504,37 individual (population density). The habitat suitability model resulted from this research can be used as a reference in identifying priority areas for better habitat management of javan hawk-eagle in the GHSNP. Keywords: Gunung Halimun Salak National Park, habitat suitability, Javan Eagle-hawk, spatial model

Abstract

Orange Footed Scrubfowl (Megapodius reindwart Dumont 1823) is classified as protected bird based on the Preservation of Plant and Animal Species of  Ministry of Enviromental and Forestry Decree No. 92/2018. As a natural park, TWA of Gunung Tunak serves as a natural conservation area (NCA) which has a basic function as a conservation area designated as a recreation area and nature tourism. Associated with its function then TWA of Gunung Tunak has an important role in supporting the conservation of wild animals especially Orange Footed Scrubfowl and the implementation of recreational activities and natural tourism in a sustainable manner. The objectives of this study were to analysis the preferential habitats of Orange Footed Scrubfowl. Based on the results of multiple linear regression analysis of stepwise method, it can be known that dominant factors to the frequency of presence of Orange Footed Scrubfowl in a selected habitat are the number of predators, the distance from water source, soil texture, and altitude of place with the equation Y = 3.390.96 + 2.28X11 + 0.00084X5 - 0.0117X10 - 0.0034X3. Based on the results of preference index analysis with Neu method, it can be seen that the preferred area of Orange Footed Scrubfowl is only in Block I (w ≥ 1) namely the forest area near Teluk Ujung Coast. Based on the place altitude, the existence of the mound of nest from the sea surface, the Orange Footed Scrubfowl prefer the area at an altitude of 0-25 m above sea level. Keywords: Megapodius reindwart, Nature Tourism Park of Mount Tunak, orange footed scrubfowl, preferential habitat

Abstract

Karang Gading and Langkat Timur Laut as wildlife game reserve, that are covered by mangrove forest and are potential region in supporting local and migratory bird life, are one of conservation area in North Sumatera Province.  Increasing population number of people surrounding the project area was also followed by the increasing of live needs Gading Beach, which is very susceptible with conversion and high exploitation.  The conflict interest requently occurs in case of converting land that caused impact to ecology and economy of properties, and indirectly affect to the decreasing of bird diversity.  The objectives of this research were to analyze the relationships between the structure and composition of tree species and the bird biodiversity.  The research was conducted from June to September 2007 in the Karang Gading Beach and Langkat Timur Laut Wildlife game reserve, North Sumatera Province.  The sampling area was selected four subhabitats consisting of (1) primary mangrove subhabitat, (2) Secondary mangrove subhabitat, (3) intensif embankment subhabitat, and (4) extensive embankment subhabitat.  A purposive sampling method was applied for mangrove vegetation, and IPA (indices ponctuels d’abundances) and CC (concentration counts) method were used for bird observe.  Results showed that there significant relationships between the structure and composition of tree species and the bird biodiversity in all subhabitats.  The correlation coefficient in primary mangrove subhabitat was higher than those of the other subhabitats.  The correlation coefficients of 0.86, 0.92. 0.85, and 0.93 were for primary mangrove. Secondary mangrove, intensive embankment and extensive embankment subhabitat, respectively.  Hight variety of tree species in each subhabitat could increase the bird diversity.   Key words: structure and composition, mangrove, bird biodiversity
