The critically endangered Sumatran elephant persists in mainly small and isolated populations that may require intensive management to be viable in the long term. Population Viability Analysis (PVA) provides the opportunity to evaluate conservation strategies and objectives prior to implementation, which can be very valuable for site managers by supporting their decision making process. This study applies PVA to a local population of Sumatran elephants roaming the Bukit Tigapuluh landscape, Sumatra, with the main goal to explore the impact of pre-selected conservation measures and population scenarios on both population growth rate and extinction probability. Sensitivity testing revealed considerable parameter uncertainties that should be addressed by targeted research projects in order to improve the predictive power of the baseline population model. Given that further habitat destruction can be prevented, containing illegal killings appears to be of highest priority among the tested conservation measures and represents a mandatory pre-condition for activities addressing inbreeding depression such as elephant translocation or the establishment of a conservation corridor.Keywords: Elephas maximus sumatranus; population viability analysis (PVA); Asian elephant; elephant conservation; Vortex Pemodelan Kelestarian dari Gajah Sumatera di Bukit Tigapuluh Indonesia: Kebutuhan Penelitian dan Implikasi untuk Manajemen PopulasiAbstractGajah Sumatera yang berstatus kritis sebagian besar bertahan dalam populasi kecil dan terisolasi membutuhkan pengelolaan intensif agar dapat tetap lestari dalam jangka panjang. Analisis Viabilitas Populasi (Population Viability Analysis, PVA) berpeluang untuk digunakan sebagai sarana evaluasi atas tujuan dan strategi konservasi yang disusun sebelum implementasi, yang akan sangat bermanfaat bagi pengelola kawasan guna mendukung pengambilan keputusan. Studi ini menggunakan PVA pada populasi lokal gajah Sumatera yang menjelajahi lanskap Bukit Tigapuluh, Sumatera, dengan tujuan utama mengeksplorasi dampak atas skenario upaya konservasi dan populasi terpilih terhadap laju pertumbuhan populasi dan probabilitas kepunahan. Uji sensitivitas menunjukkan adanya ketidakpastian atas sejumlah parameter pokok yang seharusnya diteliti untuk meningkatkan kekuatan prediksi atas baseline model populasi. Mengingat kerusakan habitat yang lebih parah dapat dicegah, untuk itu upaya penangkalan pembunuhan ilegal merupakan prioritas tertinggi di antara upaya-upaya konservasi yang sudah diuji dan menjadi prasyarat wajib untuk menjawab masalah kemungkinan dampak perkawinan sedarah (inbreeding depression) seperti translokasi gajah atau membangun koridor konservasi.

Penggembalaan ternak telah diyakini memengaruhi keberadaan satwa liar, termasuk rusa timor (Rusa timorensis Blainville 1822) melalui kompetisi. Penelitian ini bertujuan untuk mengetahui apakah penggembalaan lepas ternak kuda yang dimiliki oleh masyarakat lokal di kawasan Tanjung Torong Padang, Nusa Tenggara Timur menjadi pesaing bagi rusa timor. Observasi lapangan dan wawancara dengan pemilik kuda dilakukan untuk menentukan distribusi kuda di habitat rusa timor. Preferensi pakan dari ternak kuda dan rusa timor dikumpulkan menggunakan identifikasi spesies dari kotoran dan dibandingkan dengan plot berukuran 1 x 1 m2 di daerah makan dari kedua hewan tersebut selama musim kering dan hujan pada 2014 dan 2015. Hasil penelitian menunjukkan tidak ada indikasi yang jelas dari persaingan antara rusa timor dan penggembalaan liar kuda di kawasan Tanjung Torong Padang. Rusa timor dan kuda tidak terjadi tumpang tindih spasial dalam distribusi mereka di lokasi tersebut. Ternak kuda menempati savana perbukitan, sedangkan rusa lebih suka menempati savana dengan pohon rengit (Albizia lebbeck (L.) Benth) dan lembah dengan vegetasi hutan tropis kering. Selain itu, rusa timor lebih menyukai makan semak dan dedaunan (browser), sementara kuda lebih menyukai rumput (grazer). Kehadiran ternak lepas kuda di kawasan Tanjung Torong Padang tidak berpengaruh negatif untuk rusa timor dan habitatnyaConflict Potential of Free-Roaming Horse Grazing on Timor Deer (Rusa timorensis Blainville 1822) Habitat in Torong Padang Cape Area, East Nusa TenggaraAbstractLivestock grazing had been believed to affect on the existence of wildlife, including the timor deer (Rusa timorensis Blainville 1822) through competition. This study aimed to determine whether the free-roaming horse grazing owned by local communities in Torong Padang Cape, East Nusa Tenggara become a competitor for timor deer. Field observations and interviews with horse owners were carried out to determine the distribution of horse in timor deer habitat. Food preference of both horse and timor deer were collected using species identification from feces and compared with 1 x 1 m2 plots at feeding areas of both animals during the dry and rainy seasons in 2014 and 2015. There is no clear indication of competition between timor deer and free-roaming horses in the Torong Padang Cape area.The deer and horse avoided overlapping spatially in their distribution in the Cape. The free-roaming horse mainly occupied hilly savanna, whereas timor deer preferred to occupy savanna with lebbek tree (Albizia lebbeck (L.) Benth) and valleys with tropical dry forest vegetation. In addition, the timor deer prefer to feed shrubs and foliage (browser), while horses prefer grass (grazer). The presence of free-roaming horse in the Torong Padang Capearea does not affect negatively for the timor deer and its habitat.

Okupansi Kukang Jawa (Nycticebus javanicus E. Geoffroy 1812) di Hutan Tropis Dataran Rendah di Kemuning, Bejen, Temanggung, Jawa Tengah Mahfut Sodik; Satyawan Pudyatmoko; Pujo Semedi Hargo Yuwono

Faktor kehilangan/berkurangnya habitat, dan fragmentasi habitat dapat memberikan dampak buruk terhadap kukang Jawa (Nycticebus javanicus), satwa primata nokturnal yang tergolong dalam kategori Critically Endangered. Kukang Jawa yang hidup di hutan yang terfragmentasi merasakan dampak negatif dari faktor- faktor tersebut dan hal tersebut juga dapat memengaruhi okupansi dalam sebuah kawasan. Penelitian ini bertujuan untuk mengetahui faktor-faktor yang memengaruhi okupansi habitat oleh kukang Jawa di hutan dataran rendah yang terfragmentasi di Kemuning, Temanggung, Jawa Tengah, Indonesia. Untuk memperkirakan proporsi penggunaan wilayah, probabilitas deteksi (detection probability) dan faktor – faktor yang berpengaruh terhadap okupansi habitat oleh kukang Jawa, kami menggunakan occupancy model of a single-season. Sebanyak 5 kali ulangan survei malam pada tahun 2017 digunakan sebagai data pokok di dalam model okupansi. Metode pengambilan data lingkungan dan data anthropogenic menggunakan observasi lapangan dan interview dengan masyarakat lokal. Kami membagi lokasi penelitian menjadi 141 grid dengan ukuran 200 m x 200 m (4 ha) sebagai acuan dalam survei malam dengan jalur. Data kovariat lingkungan yang diukur adalah jarak dari jalan, jarak dari tepi hutan, jarak dari pemukiman, jarak dari sumber air, ketinggian tempat, dan kemiringan lahan. Hasil penelitian menunjukan bahwa kukang Jawa menghuni habitat sekitar 23,2% dari keseluruhan areal di hutan Kemuning. Jarak dari jalan dan jarak dari sumber air (sungai) berkorelasi positif terhadap tingkat hunian, sedang jarak dari pemukiman berkorelasi negatif terhadap tingkat hunian dari kukang Jawa. Data dan informasi kuantitatif yang dihasilkan dari penelitian ini penting untuk mengetahui kebutuhan sumber daya jangka panjang populasi kukang Jawa khususnya di hutan Kemuning. Selanjutnya diharapkan pemerintah Indonesia atau stakeholder terkait dapat melakukan upaya konservasi dan rencana strategi pengelolaan spesies kukang Jawa dengan baik khususnya di hutan dataran rendah yang terfragmentasi.Occupancy of Javan Slow Loris (Nyticebus javanicus E. Geoffroy 1812) in Kemuning Tropical Low Land Forest, Bejen, Temanggung, Central Java Abstract Habitat loss and landscape fragmentation have a negative impact on the Javan slow loris (Nycticebus javanicus), a Critically Endangered nocturnal primate species. Slow lorises in remaining forest fragments might be suffered and affect their occupancy behavior. We aim to investigate the determinant factors for the probability of habitat occupancy by the javan slow loris in Kemuning forest fragment of Temanggung District, Central Java. To estimate the site occupancy rate, detection probability, and the determinant factor of site use by Nycticebus javanicus, we employed the occupancy model of a single-season using night surveys. Five repeated night surveys in 2017 were used as the main basis data for the occupancy model. We used direct observation and interview with locals to collect data on environmental and anthropogenic features. We divided the study area into 141 grids with 200 m x 200 m (4 ha) each which were the basis for the night survey following existing walking paths. The influence of six covariates was assessed to determine of site use by Nycticebus javanicus: distance to road, distance to forest edge, distance to the settlement, distance to water source, altitude, and elevation. The result shows that the probability of site use occupied by Nycticebus javanicus was 23.2% of the total area. Distance to roads and distance to water source have a positive correlation with the probability of site use, whereas the influence of distance to settlements has a negative correlation with the site use of the species. Such quantitative data and information gained in this research are important to know for the long term resource needs of the Nycticebus javanicus, especially in the Kemuning forest. Therefore, the Indonesian Government or related stakeholders can formulate the detail conservation plans of the species, especially in the lowland fragmented tropical forest.

The Red and blue lory is an endemic parrot species from Talaud Islands, North Sulawesi. The use of existing resources is suspected that occurs of selection including the roosting trees. The research aims to identifying the characteristics of Red and Blue Lory roost tree and determining variables in its selection. We measured 14 variables to identify the characteristics and selection of roost tree. Mann-Whitney test, T-test, Chi-sqare test and Binary Logistic Regression were employed to analyze data. We detected 11 roost trees in study field, there are Gehe (Pometia coriacea Radkl) nine individual, Binsar (Ficus variegata) and Lawean (Sterculia sp) one individual. The Chi-square test identified five variables which related to roost tree selection, i.e; branch-free bole length, canopy diameter, canopy density and the number of trees around the roost tree on diameter 20 - 40 cm and > 41 cm. The Logistic regression analysis detected three variables that gave the most influence on roost tree selection, but branch-free bole length gave the most influence on roost tree selection.

Interactions between humans and carnivores have been range from positive to negative, occasionally leading to human-wildlife conflict in many parts of the world. While dogs have roles to support humans, wild dogs such as wolf, dingoes, and singing dogs have both potential positive and negative roles for humans. We gathered knowledge among tribes in Pegunungan Tengah of Papua, Indonesia on their interactions with the New Guinea Singing Dog (NGSD) using an ethno-conservation approach. We conducted in-depth interviews using both emit and etic approaches with informants from the Amungme, Damal, Moni and Dani (Lani) tribes, who live in the habitat of the dog. Data were analyzed using phenomenological, content analysis, and analytical induction processes. The four tribes have traditional knowledge about the dog and its habitat, thus forming behavioral patterns, belief systems and cultural values toward NGSD. The ethno-conservation of these tribes is reflected in their culture as results from their ability to identify the dog’s sensitivity to the change of environment including human disturbances, water quality and food availability. The tribes also limit themselves to share information about NGSD to outsiders and respect the dogs as their ancestors. Residents of the four Indigenous tribes of Pegunungan Tengah believe that NGSD is the reincarnation and avatar of the dwelling spirits of their ancestors. We discuss the implications of these findings for the conservation of this non-protected species by the Indonesian government, but endemic to Papua.

Kerusakan hutan mangrove di Desa Silo Baru menyebabkan terganggunya fungsi mangrove baik secara fisik, biologis, dan ekonomi. Upaya rehabilitasi dilakukan sebagai sebuah langkah perbaikan agar fungsi-fungsi tersebut dapat kembali berjalan sebagaimana mestinya. Selain itu, kegiatan rehabilitasi bisa memicu perubahan atau penambahan komposisi dan keanekaragaman jenis di suatu wilayah. Penelitian ini bertujuan untuk mengetahui komposisi dan keanekaragaman jenis vegetasi mangrove hasil rehabilitasi di Desa Silo Baru, Sumatera Utara. Pengambilan data dilakukan pada 4 lokasi rehabilitasi mangrove menggunakan metode transect line plot dengan jarak antar petak ukur adalah 55 m. Setiap petak ukur dilakukan pengamatan vegetasi dengan metode nested sampling menggunakan petak ukur 10x10 m untuk pohon, 5x5 m untuk pancang, dan 2x2 m untuk semai. Analisis dilakukan dengan menggunakan INP dan indeks diversitas Shannon. Hasil menunjukkan bahwa ditemukan 12 jenis vegetasi mangrove yang terdiri dari 10 mangrove mayor dan 2 mangrove minor. Jenis mangrove yang mendominasi pada setiap lokasi rehabilitasi berbeda-beda dan keanekaragaman jenis mangrove hasil rehabilitasi di Desa Silo Baru tergolong kriteria keanekaragaman rendah hingga sedang.
