“…The Javan hawk-eagle usually starts hunting in the morning because the weather is rather warm than hot. After hunting, the Javan hawk-eagle will spend most of its time resting around the nest tree (Gunawan et al 2016;Nurfatimah et al 2017;Alfiyasin et al 2018;Fahmi and Syartinilia 2020).…”

“…It is proven that the existence of Javan hawk-eagle found in the lowlands, which have habitat characteristics almost similar to the highlands. Important factors for the existence of the Javan hawk-eagle's habitat are natural forest conditions and the characteristics of trees for nesting or perching habitats (Nurfatimah et al 2017;Alfiyasin et al 2018;Fahmi and Syartinilia 2020). In the Kondang Merak coastal, the Javan hawk-eagle was found at an elevation of 0-8% (flat).…”

“…In the West Java region, it is recorded in several locations, including Ujung Kulon National Park, Gunung Halimun Salak National Park Area, Mount Salak, Mount Gede, Mount Pangrango, Mount Buleud, Mount Beser, Mount Hanjawar Timur I and Mayan Hills, Kuningan (van Balen et al 2001;Gjershaugh et al 2004;Prawiradilaga 2006;Azmi et al 2016;Gunawan et al 2016;Alfiyasin et al 2018;Fahmi and Syartinilia 2020;Septiana et al 2020;Suyitno and Syartinilia 2020). The distribution of the Javan hawk-eagle in Central of Java covers Gunung Merbabu National Park and Gunung Merapi National Park (Nurfatimah et al 2017). The distribution of the Javan hawk-eagle in East Java covers various areas such as the Gunung Picis and Gunung Sigogor Nature Reserves, SPTN 1 Tegaldlimo, Alas Purwo National Park, Bromo Tengger Semeru National Park, and Mount Ijen (Nursamsi et al 2018;Aji et al 2019;Aryanti et al 2021;Murad and Syartinilia 2021;Yuliamalia et al 2021) The Javan hawk-eagle population is threatened due to deforestation and habitat fragmentation, as well as poaching and illegal trade.…”

Abstract. Iskandar RRD, Elfidasari D, Prawiradilaga DM. 2022. Identification of spatial data and ecology of Javan hawk-eagle's nest (Nisaetus bartelsi) in the Kondang Merak Coastal, South Malang, East Java, Indonesia. Biodiversitas 23: 3419-3428. Ecological identification of the Javan hawk-eagle's habitat (Nisaetus bartelsi) is necessary to understand the support of its life, such as the spatial data in connection with its home range, nest location, and the use of nest trees. The species must choose a location that suits its needs. According to several studies, The Javan hawk-eagle's presence was only in highland forests. The new report of The Javan hawk-eagle occurrence in Merak Kondang coastal confirmed The Javan hawk-eagle's presence in lowland forest. The objective of this study was to identify the landscape characteristics that become the habitat preferences of The Javan hawk-eagle in Merak Kondang coastal, South Malang, East Java. Analysis used in this study included habitat suitability maps, plant vegetation, spatial analysis of tree canopy, and tree nest architecture analysis. The home range of the Javan hawk-eagle in the Kondang Merak coastal, South Malang, East Java, covered an area of 149.94 Ha. Most of the home range overlapped between Javan hawk-eagle individuals, including siblings and between an individual Javan hawk-eagle with other species of eagle. The Javan hawk-eagle used Spondias pinnata as nest trees with the architectural model Scarrone. It used 3 different tree species for perching, namely Pterocymbium javanicum, Anthocephalus cadamba, and Alstonia angustiloba. In the tree phase, the dominant vegetation type was Spondias pinnata (IVI) 43,16%, the pole phase that dominates was Mallotus paniculatus (IVI) 62.31%, the dominant vegetation of the stake phase was Garcinia forbesii, and the seedling phase was Arenga obtusifolia (IVI) 71.42%. The highest diversity index (H') was in the tree phase (H’=2,34), which was in the moderately abundant category and was at an elevation of 8% (flat).

“…This region also suffered by environment degradation due to the loss of 80% of natural dryland forest which result in severely fragmented habitat [17]. Habitat suitability model based on 2014 Landsat 8 OLI/TIRS in 250 m resolution concluded that only 19 suitable patches remain for Javan Hawk-Eagle [18]. Those patches located far from each other scattered all over central part of Java.…”

“…The metapopulation system will not work if the patch is isolated because there is no genetic flow of incoming movement. The cause of a patch being isolated is the distance between patches that goes beyond species dispersal capability and loss of patches around the isolated patch [17] [18]. Patch 1 (Mount Muria) and patch 19 (Lawu Mount) is a patch that has a great distance from the nearest patch.…”

Abstract. Javan Hawk-Eagle (Nisaetus bartelsi; JHE) is a law-protected endemic raptor which currently faced the decreased in number and size of habitat patches that will lead to patch isolation and species extinction. This study assessed the degree of connectivity between remnant habitat patches in central part of Java by utilizing Conefor Sensinode software as an additional tool for ArcGIS. The connectivity index was determined by three fractions which are infra, flux and connector. Using connectivity indices successfully identified 4 patches as core habitat, 9 patches as stepping-stone habitat and 6 patches as isolated habitat were derived from those connectivity indices. Those patches then being validated with land cover map derived from Landsat 8 of August 2014. 36% of core habitat covered by natural forest, meanwhile stepping stone habitat has 55% natural forest and isolated habitat covered by 59% natural forest. Isolated patches were caused by zero connectivity (PCcon = 0) and the patch size which too small to support viable JHE population. Yet, the condition of natural forest and the surrounding matrix landscape in isolated patches actually support the habitat need. Thus, it is very important to conduct the right conservation management system based on the condition of each patches.
