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

Biosphere Expeditions have continued their long term partnership with Lilongwe Wildlife Trust (LWT), researching and monitoring wildlife populations in the Vwaza Marsh Wildlife Reserve in Malawi.

The two post-Covid expeditions in 2022 and 2023 have had a particular focus on elephants and hippos as well as camera trap surveys of other wild animals. Analysis of elephant dung was also carried out to assess whether elephants had been eating crops grown in fields outside the reserve. The 2022 expedition also included a project to identify invertebrates in different habitats, as potential food source for pangolins. The 2023 expedition began the process of identifying individual matriarch and adult bull elephants. Building this database of individual elephants will greatly help in mapping the demographics, movements and health of the elephant herds in Vwaza.

The 2022 and 2023 expeditions between them counted 676 elephants over 64 sightings, 1144 hippos over 10 complete lake-side transects and collected and analysed 66 elephant dung samples (yielding 3110 seeds). More than 80,000 camera trap images were analysed, giving evidence of notable species rarely seen directly, including leopards, honey badgers, hyaena and wild dogs. The 2023 expedition also created 16 ID profiles of individual bull and matriarch elephants.

2023 expedition leader Roland Arnison, who also led the 2022 expedition, says “our citizen scientist did really well. They were quick at learning from the research methodology training, worked well as a team, and were diligent and dedicated in carrying out the research tasks every day. I am very grateful to them.”

LWT’s field research coordinator, Benni Hintz, said, “Data are absolutely critical to conservation, which is why we were thrilled to partner with Biosphere Expeditions for another year of wildlife monitoring work in Vwaza Marsh Wildlife Reserve. Thanks to the efforts of Biosphere Expeditions’ citizen scientists we were able to expand our knowledge of the movement, health and composition of wildlife populations in the reserve – particularly elephants and hippos – and had a lot of fun along the way! We’re very grateful to everyone for their hard work during yet another successful expedition.”

The Biosphere Expeditions 2023 Malawi expedition has now come to an end – successfully. We had no more drama since the attempted elephant rescue, although we did notice a lack of elephant herds visiting us near base camp since then, but quite a few sightings of elephants very close to where the juvenile elephant died (tusks removed). This is perhaps not surprising: elephants are known to mourn their dead.

We continued our research tasks right up to the end of the expedition, saving time for a celebratory sundowner by the lake on our last night, with toasts made and many group photos taken as the shimmering red sun dropped below the trees.

Benni summarised what we had achieved over the expedition:

• 218 elephants counted in 22 sightings
• 16 ID profiles created for 10 matriarchs and 6 bulls 28 dung samples collected and processed, yielding 2134 seeds cleaned, dried and photographed
• 446 hippos counted over 4 transects
• 140 observations of 97 species recorded on the iNaturalist citizen science database
• Over 43,000 camera trap pictures captured and analysed, from 18 camera traps, identifying 21 different species

This was an impressive achievement for a relatively small group of citizen scientists over a short period of time, very much a testament to the hard work and diligence of this team of experienced Biosphereans.

It has been a rewarding and successful expedition, and I am looking forward to seeing the research report in due course – and looking forward to doing it all over again next year.

Following the drama and emotion of the attempted elephant rescue (see previous blog), our expedition has largely settled back down into its regular research tasks. We have completed several transects along the lake shore now, counting hippos: enough for Benni to get at least an estimate of hippo numbers, locations and demographics. Elephant surveys are more opportunistic and we find herds and loners all around our side of the lake, and often right in front of us at base camp. On one night, a small herd crossed very close to our camp fire (they seemed unconcerned) – and got very close to our tents. With all elephant sightings we do our utmost to record as much detail as possible about the herd, down to noting unique identifiers on individual animals – notches in ears, hairiness of tail and more. This takes time and concentration and works well when we have a few citizen scientists working together, with binoculars, clipboard and a handful of essential gadgets.

The camera traps have already given us some exciting results, along with live sightings of animals we encounter when we visit the camera traps at night. Last night, a large porcupine got a fright when it walked into the track ahead of us: we got a good view of its massive spines as it marched up the track until we turned the headlights off and it wandered off into the woodland. A moment later we spotted an eagle owl, a mouse gripped tight in its talons.

Analysing the camera trap images can be an emotional exercise: flicking through hundreds of photos of waving grass is worth it for the occasional bursts of excitement on discovering evidence of iconic animals. Hyaenas and leopards have been caught on camera alongside the more expected antelope, mongoose, civets and genets.

Tonight a small team will try and record further evidence of spotted hyaenas by playing audio recordings of various animals in distress: a known research technique that can persuade a nearby clan of hyaenas at least until they get close enough to be seen in our spotlights.

We still have a few more days of research before the end of the expedition. If we carry on as we have been doing, we will have a very good set of data and scientist Benni will be happy.

Our rest day was not as restful as expected. The expedition team visited a local primary school , as planned, to tell them why we are here in Vwaza. Due to the age of the children and the need for translation, we delivered a pretty basic but fun talk about wild animals and valuing wildlife, which the school children and teachers seemed to appreciate. To extend the cultural exchange, we were invited to watch one of the community’s regular dance performances in the school grounds, which inevitably, and to much laughter all round, we all ended up joining in.

The rest day did not end there. We had had reports of a very lame young elephant seen in Vwaza, and one of our research teams had themselves spotted what looked like an injured juvenile, lying immobile on the ground next to its mother, but separated from the rest of its herd. A team of two LWT wildlife vets were dispatched from Lilongwe and leapt into action pretty much as soon as they arrived at Vwaza. Working with vets, and some local rangers, we made a plan to search the lakeside area to try and find the injured elephant (wounds caused possibly from being caught in a poachers snare, a common hazard for elephants) so that the vets could dart the youngster and its mother and inspect and treat any wounds. We searched until dark, and found a herd but no obvious sign of our target elephant.

Our search continued at dawn the next day – with no more success – before the unexpected news that a helicopter was available locally and immediately for our use for this rescue mission. Things happened rapidly after that. The chopper pilot and the two vets flew on a search pattern, while the rest of us formed a ground crew in two 4x4s ready to help as needed. Within ten minutes, the helicopter team had located the injured elephant, separated it from its mother and successfully darted it. By the time we arrived on scene, the anaesthetised animal had been stabilised and checked by the vets. The young elephant had such a bad wound on one foot – and septicaemia caused by the injury – that the vets made the decision to euthanise it, to avoid a slow and inevitable death.

We humans were sad, but this is just one of the many jobs that need to be done in conservation and its endless quest to protect and support endangered wildlife.

As we always say: Expect Plans to Change. And now, its back to our regular research work, probably – but not definitely – without any further dramatic interruptions.

Some of us were woken up in the small hours this morning by a strange sound. To me, it was the clattery rocky sound of a working quarry a few kilometres away (unexpected, at 03:00), but I was wrong. Getting up for a dawn drive at 05:00, the sound still jumping out of the darkness, I found some of the expeditioners conferring with the night guard and staring at a spot right in front of base camp, where, just visible in the murky light, was a huge herd of cape buffalo – maybe 100 of them, twitchy and in constant motion, hooves clattering and calling to each other. A new wildlife sound, for me, and one that I will not confuse with a distant quarry again.

The herd drifted into the tall grass as we began our drive. After that we enjoyed the simple pleasures of watching and recording hippos, elephants, impala, kudu, vervet monkeys and more, aglow in the red dawn as the sun rose above the lake.

With the formal training now over, the team are had at work with the research tasks involved in this expedition and have already gathered useful data including on the training days. They have all been on other Biosphere Expeditions before and the experience shows.

We are now settling into a mostly regular regime of hippo transects on foot and recording elephant herds and individual elephant IDs by car, by foot and often from base camp when the elephants wander across the river in front of us. We have also collected some good samples of elephant dung (scientist Benni is very particular about quality, and it is important to keep the scientist happy) and we have now placed all the camera traps, not without challenge: the vehicle track we use is often blocked by trees pushed over by browsing elephants and they need to be cleared with tools and muscle power if we can’t drive around them.

Our tasks from now on is to continue to gather data across all the research tasks and – during the hotter part of the day – sit in the comfort of base camp, processing elephant dung (to find any evidence of the elephants eating crops on local community land) , analysing camera trap images and entering data. We are doing well and the team is happy.
