Indonesia is still closed to overseas visitors and vaccination rates are still very low leaving much of the population susceptible to Covid infections. At this stage we are not planning to run expeditions to Indonesia in 2022. However, travel advisories and conditions on the ground change rapidly, and if by early 2022 it is looking as though Indonesia is possible, we will be bringing forward the 2023 options and running them in 2022. Our partners and the local communities with which we work are desperate for the Opwall teams to return so we would like to run in 2022 if at all possible. However, if you want to be sure of joining an expedition in 2022 then it would be best to look at one of the other countries.
There is a triangle of reefs in Eastern Indonesia that have the highest diversity of hard coral genera, the proxy commonly used to assess overall diversity of coral reefs, anywhere in the world. The Hoga Island Marine Station is located in the heart of the Wakatobi Marine National Park. Over the last 20 years, a series of scientists have been based at this site during the Opwall survey seasons and as a result, this is now the most published site in the Coral Triangle. For the last 15 years a series of constant monitoring sites around Hoga and eastern Kaledupa have been monitored for macroinvertebrates, fish communities, coral cover and community structure. The 2021 season will complete this monitoring plus some additional projects.
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 subsequently long periods 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. Since 1995, the Opwall teams have been surveying the biodiversity of Buton Island in SE Sulawesi, so that more information is now available on the wildlife of this well studied area than anywhere else in the Wallacea region. The Opwall gathered data are being used to assess the impacts of potential carbon offset funding schemes in protecting the carbon and biodiversity of the forests and ensure that local communities have a financial benefit from this conservation programme.

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.
At the marine sites during the day, the weather is normally sunny and warm (around 30 degrees Celsius), and the night temperatures drop to around 20-25 degrees Celsius. Being on the coast means there is often a pleasant breeze so it does not always feel this hot. It rains rarely, but when it does it tends to be very heavy for short periods of time.
Fitness level required
High for the forest sites. You will need to hike for long periods, over steep and muddy terrain, at times with your large rucksack. At the marine sites some fitness is required for in water activities, but conditions are relatively easy.
The Hoga Island Marine Station is an established facility that lies within the Wakatobi Marine Park of eastern Indonesia. The station was rebuilt in 2016 and supports a dive centre, lecture theatre, wet-lab as well as a large dining room and kitchen facility. Simple huts owned by members of the local fishing community surround the station and serve as guest accommodation. The island supports reliable phone signal that allows limited internet access.
