Biosphere Expeditions has completed another successful Africa volunteer expedition in Malawi, gathering long-term research data on biodiversity in one of the country’s least-studied wildlife reserves.

Conservation expedition to Vwaza Marsh Wildlife Reserve

Working closely with Malawi’s Lilongwe Wildlife Trust (LWT), the volunteer expedition team spent two weeks at Vwaza Marsh Wildlife Reserve, researching the populations of elephants and hippos around Lake Kazuni, along with surveys of other mammals and birds, using camera traps and direct observation.

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.

Malawi: Buffalos and soccer balls

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

We’ve been here in Vwaza for 10 days and on our travels we’ve observed buffalo tracks on a daily basis, but not seen one. Until yesterday when we had two teams out servicing our camera traps (more on those once we’ve processed the photos). Both encountered buffalo, with one team estimating the herd size at over 160. A great find.

Vwaza also has a number of antelope species, the most common being impala and kudu. There are also spotted bush bucks and puku. This morning we added roan to our list, a rare and exciting addition.

Our hippo transects continue to provide large amounts of sightings, with yesterday’s count exceeding 100 animals. We haven’t seen our elephant herd today, but we are working hard on updating our elephant identification sheets.

On Saturday – our day off – we went to the local town and were invited to Kizuni Primary School, where gifts from our expeditioners went down a treat, especially footballs brought by Louise sponsored by her local Canadian soccer team. We declined the offer of a game 😉

Malawi: Mammals, birds, amphibians

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

Our expedition continues to exceed expectations. We are into our daily citizen science programme. Early morning data recording drives and bird transects, followed by hippo transects and elephant surveys before lunch. The afternoons are then spent sorting and collating data and, the suprisingly popular task of sifting through elephant dung for seed analysis. In the evening we run night transects and share stories of the day.

Highlights from the last couple of days include spectacular bird shots, numerous elephant sightings and finding lion prints (which is exciting as they are rare here). We’ll put up a few extra camera traps and see whether we can catch the track-maker.

Tomorrow’s our rest day and we’re scheduled to visit the nearby school (we always get an invitation). One of our expeditioners has brought lots of footballs, so time for Malawi to win on penalties 😉

Malawi: Elephants

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

Having spotted a herd of 56 elephants mid-afternoon, the herd returned in the evening. This time their chosen route took them straight through our camp. For the next 90 minutes these gentle giants proceeded to eat their way between our tents, causing some damage to the trees, but none to camp itself. Having these animals pass close by us (we were all but one on our communal platform) rightly caused a few nervous moments and lots of excitement, but if you know how to behave around them and just let them get on with their browsing, while we get on with our admiring, then it is and was fine. After they moved on, we swept the camp, collecting some really fresh dung for study.

Malawi: Camp Vwaza

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

We’re up and running at Camp Vwaza. The citizen scientist arrived on Saturday evening – 13 people from six different countries and a good mix of science backgrounds, travellers and conservation enthusiasts.

Sunday was our first of two training days. Lea, our resident scientist introduced the team to the expedition’s citizen science tasks and the work of the Lilongwe Wildlife Trust (LWT). We had a presentation from John Stuart of the Malawi Department of National Parks and Wildlife (DNPW), which really helped in understanding where our work fits in with LWT and DNPW goals. In the afternoon we switched to more practical training, introducing the team to our survey equipment. Simon taught the navigation and range-finding skills our expeditioners need to support data collection.

We finished off the day with a short game drive as dusk approached, before Luka, our chef, produced another superb dinner. Topping of the day was a spectacular lunar eclipse. We can’t promise one every year!

Wildlife photo of the day goes to Uwe for his beautiful capture of a martial eagle. Other sightings included warthog, elephants, hippos and various antelope.

Malawi: Preparing base

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


We have made it to Vwaza base camp – a long day’s drive from Lilongwe on roads that alternate between good tarmac and bumpy dirt tracks.

It’s always a pleasure to arrive at base camp and find it in good working condition. There is still much to do to get everything ready for the arrival of the expedition team on Saturday, but the camp infrastructure is in place and working. Luka, our cook, is happy with the kitchen, which is especially important!

We heard hippos and elephants near the camp on our first evening and could make out the shadowy forms of both on the open ground in front of our campfire. The elephants were close enough for us to retreat to the safety of the camp’s communal area and carry on watching them. They seemed at ease with us and eventually wandered off.

The grunts of hippos continued through the night until the birds started calling at dawn: exotic sounds for the European ear. Today we have had good sightings of elephant, baboons and impala opposite base camp, and hippos, kudu, warthogs and many birds as we have explored around the lake side in the 4×4’s.

We have a long list of tasks over the next couple of days – checking kit and protocols, reacquainting ourselves with the wildlife reserve, and generally getting everything ready so we can start the expedition smoothly and efficiently tomorrow.

Malawi: Leaving Lilongwe

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

The advanced party has arrived in Malawi ahead of the start of the
expedition, to help with last preparations, alongside expedition leader
Roland, there is Simon, expedition leader in training. On the LWT side,
there are expedition scientist Lea and helpers Chim and Gideon.

Lilongwe is hot, dusty and busy, but not TOO hot dusty and busy! It’s fine walking around here in a T-shirt and thin trousers in the middle of the day. The Malawian government has been doing major road upgrades over the last few years and it’s now mostly complete in Lilongwe – it’s almost fun to drive on the wide new tarmacced roads now. The taxi drivers we spoke to were very happy!

We have tied up a few remaining loose ends on the expedition prep and have just set off to Vwaza with all the kit and supplies we need to set everything up for the expedition there. It will be a long day, but it will end with arrival at our wonderful base camp, with baboons, hippos, antelope and elephants waiting for us. More from there in a day or two.
