Jurnal Penelitian Kehutanan Wallacea (JPK Wallacea) was found in 2012. Initially, this journal was a regular scientifically reviewed printed journal focusing on the Conservation of Biological Resources. We are particularly interested in conservation issues in the biogeographical region of Wallacea, but related conservation issues from other parts of the world are also welcome.

Abstract

Research on richness and bird species diversity are important for conservation efforts in National Park. Currently, the Aketajawe Lolobata National Park (ALNP) is a habitat patch among industrial areas on Halmahera Island, so that it is important to carry out periodic bird inventories in the national park. Therefore, the need to study the current bird diversity and the status of bird species as a basis for future monitoring and implementation of appropriate conservation measures are important. Bird diversity research needs to be carried out because. Observation plots are placed at primary and secondary forest in Akejawi resort. The research was conducted on January to February 2022. Total observation point is 20 plots. The method was used by point count. The distance between the observation plot is 200 m and the radius of observation is 50 m. The observation were made in the morning (06.00-09.00 am). Repetition of observation on each habitat was carried out 10 times. Data were analyzed by using Shannon-Wiener Index Diversity. Based on findings, There were 345 individuals of 39 species from 19 families inhabited Akejawi Resort. Secondary forest had the highest diversity index when compared to primary forest. This study revealed  that there were 9 birds originated from North Maluku and there were 15 species categorized as protected species. The latest data can provide opportunities for further research to reveal patterns of bird distribution and various protection measures due to the loss of forest areas around national parks.

Abstract

The West Java black langur (Trachypithecus mauritius) is an Indonesian endemic primate found on the island of Java. Status and Conservation of the species is classified as Vulnerable based on the IUCN Red List and is listed in Appendix 2 of CITES. The West Javan langurs have been protected by Indonesian law since 1999. Under the decree of the Minister of Environment and Forestry Number. P.106/MENLHK/SETJEN/KUM.1/12/2018. The study aimed to examine population the population of the species and to determine its home range the forested area of Taman Safari Indonesia Bogor. This research was carried out from January to September 2021. Method The data collection used was a combination of methods concentrated Concentration Count using the observation method directly in the field. Analyze population distribution patterns using Nearest Neighbors, while the population distribution was analyzed using the area of the outermost point of encounter. The results showed that there were two groups of the West Java black langur existed in the area. The first group was around the location of the two houses, the panda palace, and the Jaksa waterfall 32 individuals and the second group was consisted of 15 individuals. Based on the survey, it was estimated that with an population density of T. mauritius in the area was 0.18 individuals/km² while the group density was 0.008 group/km². Group I was known to have a home range area of 17 ha while Group II had larger home range with 25 ha. The West Java black langur in this area were found to inhabit the upper parts of the forest at the altitude of 1000 to 1550 m above sea level. Population distribution patterns classified as clustered in all West Java black langur groups. The distribution of the West Java black langur population in TSI Bogor covers 58% of the total area.

Abstract

The Taplel waterfall area which is in the Sisimeni Sanam Education and Training Forest area is one of the conservation areas in East Nusa Tenggara which has quite high biodiversity, including plants that produce natural colors. However, information on the species diversity of dye plants in the Taplel waterfall area is still lacking. The objective of this study was to uncover the diversity of natural dye plants in the Taplel waterfall area, Sisimeni Sanam Training Forest, Takari District, Kupang Regency. Data collection was carried out by setting sample plots measuring 2 x 2 meters (seedlings), 5 x 5 meters (saplings), 10 x 10 meters (poles), and 20 x 20 meters (trees). Analysis of the importance of species using the Importance Value Index, and species diversity using the Species Diversity Index (Shannon-Wiener Index). Species of natural dye plants found in the Taplel Waterfall Area include Tectona grandis, Cassia siamea, Acacia auriculiformis, Tamarindus indica, Ficus racemosa, Leucaena leucocephala, Schleichera oleosa, Bauhinia purpurea, Cassia fistula, Garuga floribunda, and Annona squamosa L.. Plant species that has the highest important role in the Taplel Waterfall Area is Cassia fistula (sapling), Bauhinia purpurea (pole), and Tectona grandis (tree). Meanwhile, the diversity of natural dye plant species in the Taplel Waterfall Area at the level of seedlings, saplings, poles and trees is in the moderate category.

Abstract

Maleo (Macrocephalon maleo) is one of the endangered bird species in Indonesia. This avifauna species is an endemic bird to Sulawesi Island. It is distributed from the south to the north of Sulawesi, including Gorontalo. Currently, information on suitable habitat models for M. maleo is very limited, while this information is required to support the conservation of M. maleo. This study aimed to model the potential habitat for M. maleo using species distribution modeling (SDM) with vegetation cover variables as predictors. The model was built based on the M. maleo occurrence points. The suitable habitat was then evaluated using area under the curve analysis and the receiver operating characteristic curve (AUCROC). Based on the model, the AUC is valued at 0.729, which is considered reasonable and indicates that the model can be used to depict the potential habitats for the species. In this study, most of the west and east parts of Gorontalo were considered not suitable for Maleo. While the coastal areas of Gorontalo were considered very suitable. This was confirmed for both the north and south coastal areas of Gorontalo. Then it is strongly recommended to conserve and protect most of those coasts to ensure the Maleo conservation.
