“…All conservation areas are designed as biodiversity reservoir in Java (Sumardja and Kartawinata 1977;Whitten et al 1997) Pangandaran Nature Reserve (PNR) is a site for conserving biodiversity in coastal forests of West Java. It was originally established to protect the exotic plant, Rafflesia patma, and the grasslands were designed to support introduced ungulate (Bos javanicus) and Rusa timorensis (Sumardja and Kartawinata 1977;Rosleine and Suzuki 2012). Thirty-four plant families with 85 species were reported in PNR (Mitani et al 2009), such as Barringtonia asiatica, Rhodamnia cinerea, Imperata cylindrica, etc (Sumardja and Kartawinata 1977;Mitani et al 2009;Rosleine and Suzuki 2012;Azrai and Eryanti 2015).…”

Abstract. Priawandiputra W, Tsuji Y, Widayati KA, Suryobroto B. 2020. Dung beetle assemblages in lowland forests of Pangandaran Nature Reserve, West Java, Indonesia. Biodiversitas 21: 497-504. Dung beetles play crucial role in forest ecosystem, but no information on the dung beetle fauna has been reported in lowland forest of Java Island, Indonesia. Pangandaran Nature Reserve (PNR) area, which is recognized as lowland habitat of wildlife, can also support diversity of dung beetles. This study was conducted to examine the dung beetle diversity in lowland forests of PNR. The dung beetles were collected using pitfall traps baited with five species of mammal’s feces and hand collection of beetles found on dung along the road, between 2016 and 2018. During the study, 853 individuals of dung beetles from 17 species were collected. The dominant species were Onthophagus babirussa with 434 individuals (50.8%). The species were not dominant in the mountainous forests of West Java and in lowland forests of Southeast Sulawesi and East Kalimantan. The highest dung beetle abundances were found during the dry season (August): 335 individuals in 2017 and 286 in 2018. However, the diversity index value of dung beetles in this study was lower in the dry season than in the wet season (t-test of diversity index, P<0.05). The dung beetle assemblages in PNR were barely similar to most dung beetle studies of other regions.

“…The tree layer in Padar is characterized by the Bekul or Zizyphus whereas on Komodo it is the tamarind (Tamarindus indicus) (Table 3). As a comparison, in Baluran National Park in East Java, the Bekol Savanna, the dominant grass layer is the groundcover layer, which characterized by two grasses Polytrias indica and Dichanthium caricosum (Sutomo, 2017), whereas the Pangandaran savanna in West Java, the groundcover layer is of the characteristic of the secondary succession toward forest habitus, which Eleusine indica grass and the low creeping grasses Ischaemum rugosum dominates (Rosleine & Suzuki, 2013).…”

Tropical savanna and dry forest in Indonesia are an important type of ecosystem that supports various endemic wildlife of Indonesia including savannas at Padar and Komodo Islands which is home to the Komodo (Varanus komodoensis). The Komodo dragon is considered as “Vulnerable” by the International Union for Conservation of Nature. Studies with regards to the Komodo dragons’ habitats are scarce, considering that these types of habitats are significant to support Komodo’s existence, but yet are also very prone to conversion and disturbances. This paper elaborates the results of ecological study on the tropical savanna forest in Komodo National Park as habitat for the Komodo dragon. Vegetation sampling was conducted using nested plots 20 x 20 m, 10 x 10 m, 5 x 5 m and 2 x 2 m spread across the sampling sites. Data was analysed using PRIMER software which includes cluster analysis, analysis of similarity (ANOSIM) and similarity percentage (SIMPER). As many as 17 plant species which belongs to 11 families were identified in the sampling sites. These consist of six trees habitus, six shrubs, four grasses and one palm. Asteraceae, Fabaceae and Poaceae were the plant families which has high number of species. The result of cluster analysis shows that the similarity level of the two groups (Komodo and Padar) based on the results of cluster analysis is 60%. This result infers that there are similarities in terms of species composition in savanna on Komodo and Padar Island, however, each savanna still has its own species characteristics. This is confirmed by the ANOSIM test. The ANOSIM test results show the Global R value of 0.6.With the looming challenges from invasive alien plant species (IAPS), the Komodo Island’s savanna has double threats to overcome. Hence conservation of the remaining savanna ecosystem is important

“…Another cause of fires on Java Island is prescribed burning. Savannas in this wetter part of Indonesia such as Baluran National Park, Alas Purwo National Park in East Java and Pangandaran Nature Reserve in West Java require regular burning to maintain open savanna vegetation which will transition to forest areas with fire exclusion (Rosleine & Suzuki, ; Sutomo et al ., ; Sutomo et al ., ). Additionally, teak forest plantations owned by the State Forest Corporation (SFC/PERHUTANI) are also under prescribed and regular burning, such as those located in Central and East Java (Lavigne & Gunnell, ; Sutomo et al ., ).…”

This paper examines spatial and temporal patterns of large to medium‐sized fires across the Indonesian Archipelago using remote sensing, particularly the MODIS fire products, over a 14 years period (2000–13 inclusive) in conjunction with climatic and land data in a GIS. Results showed fires (burned area and number of fires) were detected the most in year 2002 and least in 2010. The extent of burning was correlated with the annual Southern Oscillation Index with most burning occurring during times of sustained negative SOI values, which generally means drier conditions across the region. Most of the detected fires occurred in the middle of the dry season and in drier eastern Indonesia. Across Indonesia, approximately 1.5 per cent of available open vegetation area burned, whereas only 0.5 per cent of forest area burned. Most open vegetation burning was detected in the savanna with an area equivalent to 11.1 per cent of its extent being burned over the 14 years. On Sumba Island, where the pronounced dry season extends for at least four months, open vegetation is the most common land cover type, of which 99 per cent burned by area over the study period making it the island with the most burned areas in the Indonesian Archipelago.
