The Langkube Valley lies within the North Buton Nature Reserve (82,000 ha) and represents a vast area of unexplored, lowland rainforest. The region supports an array of different habitats that remain largely unknown to science. Importantly, it is also a stronghold for the critically endangered dwarf buffalo (Anoa). After completing a three day ‘jungle survival’ course and learning about Wallacean wildlife and conservation, volunteers will assist a team of biologists seeking to document the valleys rich biodiversity. Biologists will focus on mammalian, avian, herpetological and amphibian faunal assemblages. Particular attention will be given to records of endangered Sulawesi endemics, such as the Anoa and the Maleo, both rarely sighted but critically important species for local conservation efforts. There exists a high likelihood that new species records for Buton Island will be made given that this expedition will be working in remote and previously unsurveyed forests. Survey techniques will include the use of camera traps, distance and patch occupancy estimates for large mammal species, mist netting for bats, standard search transects for reptiles, spotlight surveys for amphibians, pollard walks for butterflis and point counts for birds. Due to the demanding nature of this expedition, volunteers will be required to live in a basic camp environment and undertake long treks under challenging conditions.

Indonesia - Wallacea Terrestrial Research Objectives

The Wallacea region comprises islands of the central part of the Indonesian archipelago that are separated by deep ocean trenches which prevented them from being joined to the main continental land masses during the lowered sea levels of the Ice Ages. As a result of the long period of isolation, a large number of unique species evolved. The forests of the Wallacea region are one of the least biologically studied areas in the world and one of the most likely places to discover vertebrate species new to science.

Operation Wallacea first started surveying the forests of Buton Island in SE Sulawesi in 1995. In 2004 these surveys resulted in a US$1 million World Bank/GEF grant being obtained to establish an example of best practice conservation management for a lowland forest. This project worked only in the central part of the island and finished in 2008. An assessment of the various quantifiable conservation targets showed that 90%+ of the targets had been achieved and in many cases significantly exceeded. Since that point, Opwall has continued with monitoring the abundance and diversity of key taxa in both the central and northern forests of Buton Island. All the Opwall gathered data on the northern and central forests of Buton is being submitted support an application to fund a REDD+ application to protect the carbon and biodiversity of the Buton forests and ensure that local communities have a financial benefit from this conservation programme. In 2019 survey teams will be completing surveys on the transect network at a series of camps spread across central and northern Buton. Most of these survey sites have been monitored in previous years and will provide annual data to assess changes in the biodiversity over time. The rapid assessment mobile team in the northwest corner of Buton will be completing biodiversity surveys in these forests building upon primary research conducted in 2016 and they are the first ever surveys in this area.

  • Attend lectures/workshops about the Wallacea region and its ecology from published research
  • Learn survey methods to sample birds, large mammals, reptiles, amphibians, and bats
  • Learn how to conduct habitat surveys and calculate the carbon biomass of an area of forest
  • Learn skills to work and live safely in a remote rainforest research site
  • Live and work with local people and learn about Indonesian culture, customs and language
  • Work with a team of Indonesian and International scientists from around the world
  • Opwall fee
  • Cost of international flights into and out of Makassar
  • Cost of internal travel to and from the start and end point of the expedition, plus any hotels you might require. This costs around £220 or $300 on average. Extra nights’ accommodation in Makassar costs around £25 or $36.
  • Visa costs of $35 for a VOA (31-60 days, with extension), £50 for a social visa (60+ days, with extension) plus £45(VOA) or £60 (Social Visa) for the extension. Please get in touch with someone from Opwall for more detailed advice.
  • Park entrance fees – £20 or $29
  • Vaccinations and prophylactic medicines – cost can vary depending on your healthcare provider.
  • Spending money for snacks/drinks/laundry – Rupiah only
  • All prices in GBP or USD unless specified

Climate
In the tropical rainforests of Indonesia is is generally warm during the day (around 25 degrees Celsius), and humid, with up to 80% humidity. At night the temperatures drop lower, but not usually lower than around 15 degrees Celsius. It rains very frequently, and very heavily at times, but for short periods.

Fitness level required
Medium – High. You will need to hike for long periods, over steep and muddy terrain, at times with your large rucksack.

Creature comforts
Facilities in the camps are very basic (hammocks, river showers, basic trench toilets). There is no cell phone signal or internet access in any of the camps.
