Kalimantan merupakan salah satu pulau yang memiliki kekayaan hayati tinggi di Indonesia, namun kebanyakan laporan mengenai kekayaaan jenis reptil dan amfibi berada di dalam kawasan konservasi seperti Taman Nasional. Penelitian mengenai keanekaragaman reptil dan amfibi dilakukan di habitat akuatik dan terestrial dalam kawasan lindung Sungai Lesan di Berau, Kalimantan Timur pada bulan Juli-Agustus 2010. Pengumpulan data reptil dan amfibi dilakukan dengan metode Visual Ecounter Survey (VES) dimodifikasi dengan Time Search dan Line Transect (400 meter). Jumlah keseluruhan reptil dan amfibi yang ditemukan pada lokasi penelitian yaitu 31 reptil dan 31 jenis amfibi. Dari 31 jenis reptil yang diperoleh, terdiri dari dua ordo yaitu squamata dan testudines serta 9 famili dengan 2 jenis yang termasuk dalam kategori rentan (VU: Vulnerable) daftar merah IUCN dan appendix II CITES yaitu kura-kura punggung datar (Notochelys platynota) dan bulus (Amyda cartilaginea). Pada amfibi, diperoleh lima famili dua jenis masuk kategori hampir terancam (NT: Near Threatened) dalam daftar merah IUCN. Keberadaan herpetofauna ini didukung oleh adanya berbagai mikrohabitat karena berkaitan dengan pola aktivitas dan sebaran ekologis. Perlindungan kawasan ini sangat penting mengingat makin meningkatnya desakan perubahan kawasan hutan untuk peruntukan lain.Kata kunci: Herpetofauna, Kalimantan, kekayaan jenis, hutan lindung.

Ekosistem hutan dataran rendah memiliki peranan penting bagi konservasi keanekaragaman hayati. Fragmentasi yang menyebabkan terpecah-pecahnya hutan alam dan memicu terjadinya efek tepi telah menjadi kendala dalam pelestarian populasi. Memahami pengaruh habitat tepi terhadap ukuran kelompok surili (Presbytis comata) dan tersedianya data kepadatan populasi sangat penting dalam konservasi populasi. Ukuran kelompok dapat menjadi indikator kualitas habi-tat. Akan tetapi, respon kelompok terhadap tepi hutan belum banyak diketahui dan informasi kepadatan populasi surili pada ekosistem hutan dataran rendah juga masih terbatas. Penelitian ini bertujuan menganalisis ukuran kelompok surili (Presbytis comata), pengaruh tepi hutan terhadap ukuran kelompok, dan kepadatan populasi surili. Pengumpulan data dilakukan pada tutupan hutan yang mencakup hutan alam, hutan tanaman, dan kebun campuran, dengan total panjang jalur 59 km di kelompok hutan Gunung Subang, Kabupaten Kuningan. Penelitian ini menemukan bahwa ukuran ke-lompok surili bervariasi dari 2 sampai 22 dengan rata-rata 8,52 individu. Rata-rata ukuran kelompok surili tidak berubah sejalan dengan bertambahnya jarak dari tepi hutan. Kepadatan populasi surili pada interval kepercayaan 95% berkisar 44,39 – 82,36 dengan rata 60,47 ind/km2. Hasil penelitian ini dapat menjadi pertimbangan dalam penyusunan strategi konservasi populasi surili pada ekosistem hutan dataran rendah yang merupakan kumpulan dari sisa hutan alam, hutan tanaman, dan kebun campuran.

Preparation for gibbons before being released into their habitat is crucial. Thus, there is a need for readiness assessment of Javan gibbon with several criteria derived from other species of gibbons to determine individual readiness. Pre-release assessment study for Javan gibbon (Hylobates moloch) had been conducted in January â€“ February 2014, November â€“ December 2014, and March-April 2016 in the Javan Gibbon Center, Mount Gede Pangrango National Park, West Java, Indonesia. The objective of this research was to assess the readiness of Javan gibbon behavior prior to release. Data collection was conducted by focal animal sampling method with 5-minute interval recording time and ad libitum method. The average time allocations of Javan Gibbon activities were as follow: feeding (18.17Â±3.34%); moving (22.34Â±0.53%); resting (46.24Â±3.84%); socializing (10.13Â±4.33%); sexual activity (0.59Â±0.58%); and vocalizing (2.54Â±0.88%).Â The similarities of activity allocation from this study compared by wild Javan gibbons data found as follows: feeding by 33.03%, moving by 90.97%, resting by 61.52%, socializing by 38.09%, vocalizing by 75.02%, and sexual by 44.24%. Based on readiness assessment of 11 Javan gibbons, 3 individuals were considered almost ready for release, while 8 individuals were considered ready. The assessment of behaviors criteria for the readiness of Javan gibbons before release has not existed before. The results of this research are important as a recommendation for the management of wildlife rehabilitation and as a guideline in implementing the rehabilitation and reintroduction program of Javan gibbons.

Taman Nasional Kutai, Provinsi Kalimantan Timur merupakan salah satu kawasan konservasi dengan habitat yang beragam serta potensi keanekaragaman jenis herpetofauna yang tinggi. Penelitian ini bertujuan untuk membandingkan komposisi jenis herpetofauna, membandingkan keanekaragaman herpetofauna, serta menduga faktor-faktor lingkungan yang menentukan kehadiran herpetofauna pada pada berbagai tipe habitat di Taman Nasional Kutai. Pengamatan dilakukan menggunakan metode Visual Encounter Survey (VES) berdasarkan waktu yang dikombinasikan dengan jalur transek di mangrove, hutan dataran rendah, hutan kerangas, dan hutan rawa. Hasil penelitian mendapatkan 28 jenis reptil dari 9 famili serta 22 jenis amfibi yang berasal dari 6 famili. Hutan dataran rendah memiliki keanekaragaman serta kekayaan tertinggi (H’reptil =2,43; H’amfibi = 2,63). Kesamaan jenis antara empat tipe habitat sangat rendah yang menunjukkan bahwa setiap tipe habitat hanya mendukung jenis tertentu. Faktor lingkungan yang dominan memengaruhi kehadiran jenis-jenis reptil di jalur akuatik adalah kecepatan arus air, pH air, dan intensitas cahaya, sedangkan faktor lingkungan yang memengaruhi di jalur terestrial adalah ketebalan serasah, tutupan tajuk pohon, dan jarak jalur ke sumber air. Untuk amfibi, faktor dominan yang paling berperan dalam kehadiran jenis, yaitu kelembaban relatif (jalur terestrial) dan keberadaan substrat batu (jalur akuatik).

Conversion of natural forest into plantation forest at Gunung Ciremai which managed by Perum Perhutani for three decades, gaves significant destructive impacts to sulrili’s habitat and triggering surili to disperse to the more secure habitat. After the change of forest function to conservation forest in 2004, preference habitat surili is unknowing. Therefore, the initial step of the conservation efforts to restore population were by analyzing the habitat preferences surili. Chi-square analysis and Neu analysis was used to analyze the habitat preferences surili. Research carried out from September to November 2016 in Gunung Ciremai National Park. Preferential habitats characteristic of surili on Gunung Ciremai National Park are such as elevation from 1.500 to 2.400 m above sea level, densely forest stand >50%, distance to the edge of the forest (0-665meter), distance to the settlement (0-806 meters), distance to the hiking trail (0- 1572 meters), surface temperature 16,3-18,5°C, steep slope (25-40%), preference for habitats that is secondary forest cover.

In natural habitats, every organism including wildlife interacts with another individuals both in one species (intraspecific) and with other species of (interspecific), and each interaction can be positive, negative or neutral. In deer captive breeding of Cariu Bogor, three species of deer were bred namely bawean deer (Axis kuhlii), timor deer (deer timorensis) and spotted deer (Axis axis), but so far the interspecific interaction among the three species has not been known comprehensively. This research was conducted to aim (1) calculate the time usage for activities, (2) calculate the period of space usage and homerange width of each deer species in the captive area, (3) niche breadth and the scores of niche overlap , (4) the characteristic of interspecific interactions, and (5) the presences or absences of cross-breeding among the three deer species that are bred. Data was collected through field observations by recording activity period, time and place of deer presence simultaneously and the attitude or response given by individuals of different deer species, movement mapping and space utilization in four types of habitat also the types of plants consumed, then analyzed with several methods such as Chi-square test, Levins and Hulbert niche width and Morisita index. The results showed that the three deer species had different time and space usage. Most of the time is used for eating and resting in the grasslands. The homerange area of the three deer species are different, where the bawean deer have a wider homerange (3.6 ha) than spotted deer (2.6 ha) and timor deer (2.2 ha). The results of niche breadth calculation showed that the bawean deer had wider niche (4.3) than the spotted deer (2.1) and timor deer (1.6), with the percentage of niches overlap by Morisita index between bawean deer and spotted deer is 95%, between bawean deer and timor deer is 70.5% and between spotted deer and timor deer is 96.6%. Interspecific interaction among the three species is neutral (zero), and there is no crossbreeding between the three species of deer that are bred simultaneously in one breeding area. Keywords: captive breeding, crossbreeding, interspecific interaction, niche overlapping, three deer species

Repeated forest fires highly impact on tree species composition. Forest planning requires information about the current condition of species composition. This paper investigates the current tree composition of natural regeneration after repeated forest fires, regeneration process after repeated fires, and strategy of secondary growth related to ecological restoration issues. Re-observation of the 1.8 hectares permanent plot in Samboja Research Forest was conducted in 2011. All trees with diameters above 10 cm at breast height (DBH) were re-numbered and mapped. Herbarium specimen was collected for species identification. Number of taxon was determined, Important Value Index was calculated, species trait of light response was identified based on the references and dispersion index species was calculated. Results show after twenty eight years initial forest fire, 191 species naturally regenerated in the burnt area. Macaranga gigantea, a light demanding pioneer species of Euphorbiaceae was the most dominant species, followed by Vernonia arborea belonging to Asteraceae. Both, M. gigantea and V. arborea had clumped distribution. Eight species identified survived from repeated fires, are Anthocephalus chinensis, Dipterocarpus cornutus, Diospyros borneensis, Eusideroxylon zwageri, Shorea ovalis, Syzygium borneensis, Pholidocarpus majadum and Vatica umbonata. All surviving species was distributed uniformly in the plot. Dominant pioneer species which has grown after repeated fires indicates that the current condition of burnt forest is in the early succession. Protecting forest, assisting natural regeneration and monitoring dominant species are suggested as activities for the ecological restoration.
