Activity pattern and habitat association of Assamese macaques Macaca assamensis McClelland, 1840 in Shivapuri Nagarjun National Park, Nepal

Assamese macaque Macaca assamensis McClelland, 1840 is one of the primate species with narrow distribution range and the least exploration. This study investigated the diurnal activity of Assamese macaque and association with the vegetation in Nagarjun Forest of Shivapuri Nagarjun National Park, Nepal. Behaviour sampling including Instantaneous sampling and Ad-libitum sampling (7:30 AM – 4:30 PM) along with vegetation survey (20 m × 20 m plots) were applied. The Raniban Barrack troop of Assamese macaque composed of 12 individuals was observed for a total of 225 hours to record the macaque’s diurnal activity. The troop spent 28% time in inactive, 25% in grooming, 23% in foraging, 23% in locomotion and 1% in fighting. Assamese macaque troop spent more time in Schima wallichii possessing 25.91%, 36.29% and 41.22% for foraging, locomotion and inactive respectively of the diurnal time. Altogether, 67 plant species (herbs, shrubs, trees and climbers) were documented from vegetation analysis. Schima wallichii and Ardisia macrocarpa were dominated the habitat. Paired t-test revealed significant difference in foraging (df = 24, P = 0.010) and inactive (df = 24, P = 0.003) between the morning and day observational phases. The findings of this study shed light on the food preference and microhabitat use by the protected Assamese macaque in Nepal that assists to formulate the management plans for the species.

Natural colonization of vegetation under twenty years restoration of ex-cement mining

Biodiversity loss can be drastically aggravated by mining activities. Opened pit mining removes all material, including vegetation, above the ore deposit. Cement industries always implement opened mining as they process all rocks into cement. Restoration is known as the best human interference to drive the damaged ecosystem to recover. This study aimed to observe vegetation that was naturally grown under Pinus sp after 20 years of planting on ex-cement mining. The study was conducted in Sukabumi District, in three sites that were distributed in Cicantayan (2 sites) Sub District and Cibadak Sub District. Each location disses ivided into three points to conduct analysis vegetation in transects, for trees 2 units (10 x 10 m), shrubs 4 units (5 x 5 m), and grasses 5 units (1x1 m). The study resulted after 20 years of planting with Pinus (3 x 3 m) the sites recorded have been inhabited by 13 new species. They are 4 woody trees species, 4 species of shrubs, and 5 species of under-story (grasses). Tree stratum new inhabitants are Ficus spp, Macaranga gigantea, Schima wallichii, and Hibiscus tilliaceus, with the important value index (IVI) 57.83%; 53.67%; 33.17 %, 26.5%; respectively. Shrub’s stratum is inhabited by Mimosa invisa (IVI 76.66%); Eupatorium odoratum (IVI 76.66 %); Melastoma malabathricum (IVI 73.83%); and Clibadium suninamensis (IVI 72.837%). Whereas grasses stratum inhabited by Imperrata cyllindrica (IVI 98.77%); Brachiaria decumbens (IVI 98.60%); Themedia gigantea (IVI 43.11%); Setaria spp (IVI 31.83%), Cymbophogon citratus (IVI 27.69%). Shortly, restoration has encouraged natural colonization even acid mine drainage on the body waters remains occurred.

Penyebaran Jenis Puspa (Schima wallichii (DC.) Korth) di Resort Kawah Ratu, Taman Nasional Gunung Halimun Salak, Jawa Barat

Puspa (Schima wallichii (DC.) Korth.) is a type of plant that dominates the area of Gunung Halimun Salak National Park, especially at Kawah Ratu Resort. Puspa type is one of the upland plant species that can grow in critical land. The objective of this study is to identify the distribution pattern and the potential for regeneration of puspa species (Schima wallichii (DC.) Korth.) at Kawah Ratu Resort, Gunung Halimun Salak National Park, West Java. Data were collected by analyzing vegetation with a single plot method covering an area of 1 hectare at each location. The research was conducted in the Pamengpeuk Block and the Leles Block. The species found in the two research locations were 98 species. The results showed that the distribution pattern of puspa was clustered, both in the Pamengpeuk block and in the Leles block. A clustered spread indicates good youth growth. The ability of puspa regeneration in both locations was quite good because the number of puspa regeneration individuals was more than the individual trees.

KOMPONEN KIMIA ORGANIK LIMA JENIS ASAP CAIR

Beberapa tanaman seperti kakao (Theobroma cacao), alpukat (Persea americana), puspa (Schima wallichii), sengon (Falcataria mollucana) dan tarik angin (Usnea sp.) banyak ditanam di masyarakat untuk kebutuhan buah-buahan atau kayu. Secara periodik, masyarakat memanen jenis-jenis tersebut untuk dimanfaatkan kayunya atau peremajaan tanaman. Pada umumnya, sortimen kayu digunakan untuk konstruksi sederhana, atau dibakar. Selain teknik pembakaran konvensional untuk menghasilkan arang, ada produk lain yang dapat dihasilkan yaitu asap cair menggunakan teknik pembakaran dengan menambahkan kondensor untuk menghasilkan asap cair. Asap cair memiliki kandungan kimia organik dengan beragam manfaat. Studi ini bertujuan untuk menganalisis kandungan kimia organik jenis asap cair dari jenis kayu kakao, kayu alpukat, kayu puspa, kayu sengon dan kayu tarik angin. Kelima jenis material studi dikarbonisasi menggunakan reaktor pirolisis pada suhu 400°C. Asap cair didapat dengan cara kondensasi uap karbonisasi kelima jenis tersebut. Analisis kandungan kimia organik asap cair menggunakan kromatografi gas-spektrometer massa (Gas Chromatography Mass Spektophotometry, GCMS) Pirolisys Type QP2010 dan High Performance Liquid Chromatography (HPLC). Analisis GCMS menunjukkan bahwa asap cair kayu kakao memiliki konsentrasi kelompok asam tertinggi, yaitu 45,53%, sementara konsentrasi asam asetatnya adalah 31,81%. Kehadiran kelompok fenol tertinggi terdapat pada asap cair kayu alpukat sebanyak 56,86%, di mana konsentrasi senyawa fenol mencapai 41,92%.

Kata Kunci: Elang Jawa; Habitat; Sarang; TNGHS ABSTRACTOne of the birds of prey found in Indonesia is the Javan Hawk Eagle (Nisaetus bartelsi). Mount Halimun Salak National Park (TNGHS) is one of the national parks in Indonesia. TNGHS is one of the habitats for Javanese eagles. This is because the conditions are still quite good and data on Javanese eagles in the TNGHS area are still inadequate. Therefore, it is necessary to explore the habitat of the Javan hawk population in the TNGHS area. This study aims to explain the habitat and nest of Javanese eagles which include location, tree species and tree characteristics used as a place to place nests in TNGHS. This is useful for providing information about the Javan hawk nest habitat in the area. The methods used are surveys, nest monitoring, interviews, data collection and analysis. Based on the observations of N. bartelsi, using the tree Litsea cordata (Huru) with a height of 40-60 meters as a nest, and the tree Schima wallichii (Puspa) for perching.Keywords: Javan hawk eagle; Habitat; Nest; TNGHS

Importance of Trees Outside Forest (TOF) for immediate earthquake response

A study was carried out in Thulosirubari village of Chautara Sangachowkgadi municipality of Sindhupalchok district, Nepal to analyse the importance of TOF for immediate earthquake response and recovery. More than 80% of the households have trees in their own land with species such as Chilaune (Schima wallichii), Kutmiro (Litsea monopetala), Khote Salla (Pinus roxburghii) and Bamboo are common. Among surveyed households (134), more than 75% respondents reported that they used Schima wallichii for pillar (Khaba) to make temporary houses, whereas bamboo was used for all kind of poles (Dada/Vata/Balo) in more than 80% of temporary houses. Both Bamboo and Schima wallichii were either extracted from their own land or from neighbour's land, i.e. TOF which were easily available and collected as required. We could not draw any statistical conclusion in choice of species to construct temporary houses by wealth categories. However, we have observed that people who have sufficient and varieties of trees in own land, have selected strong and hard wood for permanent house construction whereas those who do not have choice, are limited to use any of the available tree species. People were highly aware about importance of trees to cope with disaster; however selection of species was still debatable because of limited knowledge and researches. J. Biodivers. Conserv.
