Maldives: Hope

Update from our Maldives coral reef and whale shark expedition

We have found some hope in the gloom. The last reef we assessed, was – in the words of Simon, our expedition scientist – “what a reef should look like”. Great coral cover, quite a few fish, almost no bleaching and very little coral disease. So the expedition ended on a high, as well as some outstanding karaoke, especially from the crew, who had some impressive dance moves in store.

In between the weather tried to thwart us, but we are undeterred, dodging and weaving the squalls, laughing at the sheets of rain and delighting in the sunshine.

We checked lots of reefs like clockwork. And this is exactly what makes an expedition: a journey with a purpose. Our purpose was assessing reef health, revisiting sites and continuing to add to what is now an impressive 12-year database.

Thank you, expeditioners – none of this would exist without you. We hope we also brought some clarity to your own purpose and thinking during what was an all-round very successful expedition.

Maldives: Sickness & Health

Update from our Maldives coral reef and whale shark expedition

Group 2 is now also qualified – well done – and checking those reefs.

The stories are as mixed as has been the weather. There are some quite healthy reefs and some that are sick.

Fish are scarce, especially grouper, because there is immense fishing pressure due to (over)tourism and a very active grouper fishery that sells them off as food fish, mainly to Hong Kong as live fish for restaurant aquariums there.

Maldives: Round 2

Update from our Maldives coral reef and whale shark expedition

Here we are back again with a smaller, but equally keen group 2.

The weather has turned and it’s more windy, greyer and rainy now. But underwater it’s wet anyway.

We’ve done our check-out dive and are well into our training sessions now. Lectures, pointy dives and fish test today. The proof will be in the pudding.

Maldives: Stable recovery

Update from our Maldives coral reef and whale shark expedition

Group 1 has checked all the reefs on its schedule, well done!

All were repeat surveys to track reef health and development over the years, one of the great advantages of citizen-scientist-funded expeditions, which can fund projects sustainably and reliably for many years (since 2011 in the case of the Maldives), generating long-term datasets that result in many insights and scientific publications.

None of this would happen without the many, many citizen scientists over the years who come to fund and help with this research and conservation work. Thank you!

Maldives: Mantas and corals

Update from our Maldives coral reef and whale shark expedition

We’re in the groove now and checking those reefs like clockwork – well done team 1.

We moved to Alifu Dhaalu (South Ari) atoll and studied a couple of sites there, as per our schedule. They were outer sites and coral cover was unchanged from when we visited them last in 2023 (still few fish, as has been the case for more than a decade now – they are just being overfished). The good coral cover, however, is positive news, showing some resilience.

Maldives: Half checked

Update from our Maldives coral reef and whale shark expedition

Team 1 is delivering and so is the weather – and the reefs.

After two days of intensive training, we’ve checked our first reef, well half of it, were it not for our very own two Daft Punks reeling in the survey line whilst people were still busy with the survey :))

But that’s exactly what the very first survey is for – after 48 hours of crash coursing – to get familiar with how it all comes together underwater. So no sweat and same again this morning, as per ze schedule, ja!

Maldives: On board

Update from our Maldives coral reef and whale shark expedition

Liveaboards in the harbour

Expedition scientist Simon and I have arrived on our liveaboard base in the Maldives and are setting up as we speak.

The liveaboard harbour is – against expectations – still here and has not been filled in for housing. We have a quiet corner amongst other liveaboards although there is some hammering and shouting going on as I type this as last minute repairs are done.

Malawi: Expedition achievements

Update from our Malawi expedition volunteering with elephants, hippo, cats, pangolins and African biodiversity

The 2025 Malawi Expedition has now finished and I am happy to reflect on another successful expedition, with a great group of expeditioners, some memorable highlights and a lot of good research data collected.

This is an expedition with multiple research projects: elephant herd observations, hippo transects, elephant dung analysis, camera trap survey, night transects, bird transects and an iNaturalist project, which gives a record of all interesting species spotted opportunistically.

We have done well on all of these and uploaded a large set of data for the expedition scientist to analyse and write up.

A provisional summary of some of what the 2025 expedition has achieved:

Malawi: Leopard and more

Update from our Malawi expedition volunteering with elephants, hippo, cats, pangolins and African biodiversity

Vwaza continues to deliver amazing flora and fauna, with some great results on our second round of camera trap checks.

We have now finished collecting data and we are working through the collation of our bird and hippo transects, elephant spotting, elephant ID and dung analysis.

This year we have updated a number of our elephant profiles and added a few new ones.

Malawi: Camera trapping

Update from our Malawi expedition volunteering with elephants, hippo, cats, pangolins and African biodiversity

Camera traps are a vital tool in our data collection efforts. Vwaza has many species that we see during the day and we can record from our own visual observations. But at night the forest and lakeside are teeming with life that we would not necessarily pick up. 

The expedition team set up 25 camera traps and serviced them halfway through the expedition. Some were unsuccessful – a stray  branch can trigger the motion sensor and we had one knocked off by a passing elephant. The others provided some exciting photos of porcupine, cape hare, civet and serval appear. No big cats yet.

This is an update from our Malawi volunteer expedition. You can find an overview of all our current expeditions here.
