Abstract

Lampung Province has the threat of Forest and Land Fires (FLF) based on incident reports. There is a lack of data on how the threat level of the forest and land fires, so this research is important to do. This study aims to analyze the track record and potential for FLF incidents, to analyze the characteristics and level of the FLF threat. Threat mapping is done by weighting and scoring 11 variables. These variables are divided into natural factors and human factors. The results showed that the equation that gives a weighting of 90% to natural factors. The characteristics of FLF show that natural factors are sensitive factor for the occurrence of FLF in Lampung Province. Mapping of threats shows that the area of ​​low threat class is 244,811.96 ha (8%), medium threat class is 1207,716.15 ha (40%) and high threat class is 1,591,767.42 ha (52%). Three districts had the highest level of threat class, namely Way Kanan, Central Lampung, and East Lampung Districts. The results of the validation of field conditions are indicated by the results of this threat mapping, so that the results of this study can be used as material for consideration by policy makers.

Abstract

Conflict between human and elephants in Tesso Nilo National Park encourages WWF to establish the Flying Squad. Related to the function of the sumatran elephants in Flying Squad as the patrol team, it is necessary to conduct a proper management to ensure animal welfare. This study aims to examine the aspects of welfare management and asses the level of welfare of sumatran elephants in Flying Squad. The research methodology used for this study are literature review, interviews and field observation. Data analyzed by describing the suitability of management and tabulating the assessment. The management of cages, feed, health and reproduction requires some improvements such as the type, number and equipment of the cages, natural feed adequacy, medical infrastructure and reproduction management. The 76,98% percentage rate of sumatran elephant welfare, which is relatively good, is because there are only 14 priority components of 43 components of animal welfare assessment that need improvements and enhanced management. Keywords: animal welfare, flying squad, the patrol elephant

Abstract

Land-use change from a rubber plantation into the ITERA campus area causes an ecological transition. The components of ecology affected are vegetation and wildlife (bird). Geographic information systems can be used to assess the condition of vegetation and its relation to the ecological component. This study analyses bird diversity, vegetation condition through the NDVI value distribution, and then analyses the bird distribution based on vegetation condition. Observation in transect is the method for collecting bird distribution data. Analyses of vegetation condition was carried out based on NDVI. Analyses of bird distribution based on vegetation condition was carried out spatially by overlaying thematic maps of vegetation with bird distribution. This research found 28 bird species belonging to 18 families with diversity index (H’) 1.84. The highest abundance species were Lonchura punctulata, Passer montanus, and Hirundo tahitica. The NDVI values ranged from -0.64-0.87. ITERA vegetation conditions are divided into five classes: very rare vegetation (VRV), rare vegetation (RV), m vegetation (MV), dense vegetation class (DVC), and very dense vegetation (VDV). Total encounters with birds in this study were 753. The distribution of birds to the vegetation conditions in ITERA has a higher tendency and diverse vegetation have implications of birds to use the vegetation. In the VRV class, there were 4 encounters, RV 37, MV 157, DVC 235, and VDV 315. Also, the number of bird species tends to increase along with the increasing vegetation value. Lonchura punctulata is a bird with the highest abundance in each vegetation class, followed by Passer montanus and Pycnonotus aurigaster. Key words: bird distribution, ITERA, land-use change, vegetation condition

Abstract

Land use change of rubber plantation into ITERA campus area has led to changes in the ecology of the area. Amphibians and reptiles, referred as Herpetofauna, are categorized as wild animals that are sensitive to environmental changes and are considered as bio-indicators. Wild conservation activities including herpetofauna is an essential part to the forest campus concept in ITERA. The objective of the study is to analyze the diversity and distribution of herpetofauna. This applied Visual Encounter Survey (VES) with Time Constraint Method and Glue Trap technique. This research was carried out on six observation path and 180 traps. The ecological index analysis consisted of species diversity, evenness, richness, abundance, and community similarity. Twenty-two herpetofauna species were found, including nine amphibians (5 families) and 13 reptiles (9 families). There was one reptile species with vulnerable conservation status and 3 reptile species included in CITES appendix II. The diversity index value (H ') was 2.29; species evenness (E) value was 0.74; and species richness value was 3.33. Amphibian species with the highest abundance was Fejervarya cancrivora 1.78 individual/hour of observer, while from the reptile species was Hemidactylus frenatus 0.35 individual/hour of observer. There were 550 herpetofauna encounters, where 8 species could be found on all transects and 6 species could only be found on one transect. This research showed that the condition of ITERA habitat currently supported herpetofauna's life and needed conservation activities to maintain herpetofauna diversity.

Abstract

Flying Squad (FS) WWF is a human-elephant conflict mitigation program that has been operated for 13 years. This program operates in Tesso Nilo National Park (TNNP) at high conflict density. The management of FS captive elephant is performed by grazing in TNNP forest area. The existence of grazing activities, the operational time and the threat of deforestation will certainly affect the availability of feed and feed carrying capacity. This study aims to analyze feed diversity, palatability, and feed carrying capacity at the operational area. The method used for this study are 60 plots of vegetation analysis, interview, literature study and destructive measurement method by making 30 productivity plots of ground cover plants and observed for 2 months. The study found 110 feed species from 47 families. Within 6 hours of palatability observation, average elephant can grab the feed for 1959 time and the highest feed palatability is Rhynchospora corymbosa (L.) Britton. The total of feed productivity from ground cover plants is 82.027 kg/day. Carrying capacity at 1714 ha area is 161 elephants.

Abstract

Ranggawulung urban forest is one of the remaining vegetated sites in Subang. That place needs to be managed sustainably because of its potential to be a strategic location for biodiversity. Biodiversity studies in Rangawulung urban forest need to be conducted periodically to assess and control the impact of urban development. This study was undertaken to evaluate biodiversity in Subang City, especially Ranggawulung Urban Forest as an indicator of biological management in urban areas. There were ten species of mammals found in the Ranggawulung City Forest area from six families. One of the species found, the Javanese slow loris (Nycticebus javanicus), is a protected animal in Minister of Environment and Forestry regulations (PermenLHK Number P.106/2018). The animal is categorized as CITES Appendix I and Critical according to the IUCN red list. Diversity (H'), richness (Dmg), and evenness (E') indices of the area species were 2.03, 2.06, and 0.92, respectively. Ranggawulung Urban Forest is considered important as an animal habitat in Subang City and needs to be managed properly and sustainably.

Abstract

Ranggawulung City Forest is a Green Open Space (RTH) located in Subang City. As one of the remaining forests in the middle of an urban area, this urban forest has great potential as a location for biodiversity management. This research was conducted to determine the value of biodiversity, especially herpetofauna in Ranggawulung City Forest, Subang City as an indicator for evaluating the success of environmental management in the future. This study uses the Visual Encounter Survey (VES) method modified with Time Search. The herpetofauna diversity (H') in general observed in the Ranggawulung City Forest was 2.59 in the HKR block, and 2.34 in the Buper block. The value of species richness (Dmg) in each block is 4.41 and 3.40. The two areas are relatively evenly distributed with an evenness value of more than 80%. There were no nationally protected species of herpetofauna, two of which were species whose trade was restricted internationally and were included in the CITES Appendix II category.
