Leptoptilos javanicus

bangau-tong-tongAceh Besar is one of the districts in Aceh province, Indonesia. It located between Banda Aceh City and Aceh Jaya District. With an average altitude of 125 meters above sea level. Most area of Aceh Besar located at the upstream of the river.Land cover reached 62.5% (according to data from Landsat in 2007). Temperatures ranged an average of 25 ° C – 28 ° C. The forest area in the district of Aceh Besar divided into protected forest area of ± 71444.27 ha, with preserved and Nature Conservation ± 25475.59 ha, there is also a permanent production forest and other forest use. For this project, the Lhoong forest located at village of Krueng Kala with a distance of about 75 kilometers from the west of the Banda Aceh city. On the earthquake and tsunami in 2004, the area is also affected significantly, many ecosystems degrade and change.
 Leptoptilos javanicus is an endangered species with vulnerable categories by the IUCN Red List (IUCN, 2006). Between of 18 species of water birds ever recorded and counted in the Indonesian census are protected by law in Indonesia. Leptoptilos javanicus including one of 18 species of water birds are protected. This project will be importance to maintain the stability of populations, habitat ecology,, increase the populations, and offspring survival L. javanicus. Efforts to maintain the population can be done by keeping the ecological habitat from damage or disturbance. Habitat serves as a place to find food, drink, rest and breed. Bird is one indicator of the quality of the habitat. Because the birds are very sensitive to environmental changes. The existence of L. javanicus is a wealth of diversity for the Indonesian state. The common factor causing the decline of L. javanicus is the transfer of land use, disturbance of bird habitats, natural predators, pollution, human activities around the forest. But in Aceh forest, habitat type and cause of the declining population of L.javanicus yet to be explored, and this program is one way to get that data.


Bangau Tong Tong

This stork is including birds protected under Indonesian law, as set forth in Appendix PP 7 1999. Collar & Crosby (1994) grouping stork L. javanicus with vulnerable status, with an estimated population of 10,000, with the largest populations are in eastern Sumatra (Elliot, 1994). This species that has the highest preference value as a tourist attraction based on the percentage of frequency relative citation index with the local name “ bangau tong-tong” , the RFC index value is 92.6 % which means that 125 of the 135 respondents said that Leptoptilos javanicus interesting to used as tourist attraction, the next bird is hypoleucos( 91.1%), Centropus bengalensis (89.6%) and Halyconcyanoventris (88.1%) (Prastiyo, Luchman Hakim, Jati Batoro; 2015). They habitat destruction caused human disturbance and excessive captching (Subaraj, R and Lok A.F.S.L. 2009). However the use of pesticides in the croplands, poisoning, likes and river alternation have been a serious attention (Pokharl.1998 in Gwayali. 2003). L.javanicus species distribution is influenced by annual rainfall. It is also influenced by the emergence of a climate period temperatures of the year , this is key to the spread of the species. This means that the effects of climate change and global land use is an important factor in the spread of bird (Khadka KK and Pandey R, 2013). In Indonesia, L.javanicus nests were found at Sumatra, Kalimantan, Java and Bali (Boediono et al, 2007).

As a conservation biologist we rate these species have increasingly endangered due to habitat loss, especially eating and nesting habitat. Including water quality deteriorated thereby increasing mortality. The first observation results showed that there was a decrease in the number of species from year to year. I hope this project can increase the quantity of species in direct or indirect. Natural aceh as organization need requires a track record of the rate of increase in the threat of extinction this species (Leptoptilus javanicus) so that the protection and issue of this species can be monitored.
