Abstract

Gunawan H, Iskandar S, Sihombing VS, Wienanto R. 2017. Conflict between humans and leopards (Panthera pardus melas Cuvier, 1809) in Western Java, Indonesia. Biodiversitas 18: 652-658. Conflict between the Javan leopard (Panthera pardus melas Cuvier, 1809) and humans occupying the same region have tended to increase in the last decade in proportion to increase in deforestation followed by fragmentation and habitat loss. The objectives of this research were to study the leopard-human conflict and to analyze the causes in order to formulate recommendations for mitigation. Literature study, structured interviews, and field surveys were carried out to collect data on leopard-human conflict. Spatial modeling using weighted overlays generated a map of conflict potential in Western Java. The results showed that in the last 15 years 71 cases of leopard-human conflict had been recorded, with a tendency to increase over time. There have been 75 records of occurrence of the Javan leopard population in Western Java, of which 30% are assessed to have had a high potential for conflict; 25% had moderate potential, and 46% had low potential. There are indications that leopard-human conflict has occurred in villages around degraded forest areas due to human encroachment and cultivation. Consequently, a special forest management strategy must be implemented on a landscape scale, crossing the boundaries of conservation forest, productive forest, protected forest and other land uses.

Abstract

Gunawan H, Sugiarti, Iskandar S. 2017. Dynamics of mangrove community in revegetation area of Karangsong, north coast of Indramayu District, West Java, Indonesia. Biodiversitas 18: 659-665. Mangrove along the north coast of Java is heavily degraded due to the conversion of land into fish ponds and human settlement areas. A revegetation program has been initiated by the local community of Karangsong Village, Indramayu District, West Java, Indonesia, supported by PT. Pertamina RU VI Indramayu. Our research aimed to study the population dynamics of the mangrove revegetation in Karangsong. Secondary data was collected from the Fishery and Maritime Services of Indramayu and PT. Pertamina. We carried out on-location field observations and we interviewed key respondents. Data was analyzed to describe trends in the diversity index and population dynamics of the mangrove. It was observed that the revegetation effort in the shoreline of Karangsong had covered ± 69.08 hectares which consisting of six species of mangrove and three tree species of coastal vegetation i.e. Rhizophora mucronata Lam., Rhizophora stylosa Griff., Rhizophora apiculata Blume, Avicennia marina (Forssk.) Vierh., Avicennia alba Blume, Sonneratia caseolaris (L.) Engl, Terminalia catappa L., Casuarina equisetifolia L., and Ziziphus mauritiana Lam. The mangrove population increased dramatically, from estimated 25,000 individuals in 2008 to 690,835 individuals in 2016. Rhizophora mucronata was the most dominant species (68.85%), followed by Rhizophora stylosa (18.33%) and Rhizophora apiculata (9.53%). The Shannon diversity index was fluctuated but tend to be increased from 0.80 to 0.95.
