A holiday spent doing elephant science: Part II (some science, some other stuff)

Okay, so every day wasn’t elephant counting and monitoring and dung sampling. Yes, I really went to South Africa for my vacation and spent at least a small amount of time looking at, taking photos of, measuring, and rooting around in, elephant dung.

Read Part I of this series here. And read about the Bring the Elephant Home program and our mission: What happens when you drop a fence.

The Bring the Elephant Home program was structured to give us several days in the field, a day or two in the “office” doing projects (I wrote a blog post, created a few new visuals for the team, and contributed a BUNCH of photos for the ID project… and I’m trying to put together a Hackathon project to use AI for elephant ID. More to come on that as it progresses!), and time to see the local area and learn even more about Xhosa culture.

We watched some presentations on other conservation being done in South Africa and abroad, one by Bring the Elephant Home’s Antoinette van de Water on her work on the value of elephants [read the white paper here, or take a look at her TedTalk here], and by the amazing work being done in rewilding by Brett Mitchell of the Elephant Reintegration Trust. Their motto, “helping elephants in captivity or distress to gain the freedom they deserve” says volumes about the work they’re doing. (Know any gajillionaires? A new project they’re working on to create a sanctuary and rewilding center near Kariega needs funding. Let me know and I’ll put you in touch with the right people!).

A small public service announcement: If you are fortunate enough to see elephants in their native land and have the opportunity to ride or touch captive elephants, please DON’T! Just please don’t patronize these businesses. These types of business exist at the expense of the health and welfare of the animals. [read more here]

Elephants are sentient, endangered beings, mistreated and quite often drugged in order to be submissive enough for human entertainment; in the process they suffer years of emotional and physical hardships. Having seen captive elephants first-hand in Thailand and India, and wild elephants in Africa, I can assure you that there is nothing more exquisite than watching a wild elephant in its natural habitat. There is absolutely nothing satisfying about watching a captive elephant. [rant off]


One of the events later in the week was an offsite visit to the home of one of the Kariega Foundation’s staff for an afternoon cooking demonstration! Xhosa cuisine is comprised of quite a lot of meat, but also their staple starch called samp, a corn meal derivative that seemed a lot like the East African fufu or ugali, made with cassava, that I tried in Botswana and Zimbabwe. Beans or sauces (meaty and non) are poured over the samp, as other cultures would use rice or potatoes.

Lunch!

Fears of cultural appropriation dancing in my head, our faces were dotted with Xhosa-style paints, and we donned handmade clothes and beaded neck wraps. Our smiling hosts guided us into the kitchen and outside to the fire upon which we heated stews and baked the bread we had just hand-rolled. Note: It was a bad time to have quit bread, as these hot-off-the-fire rolls were simply divine. The afternoon culminated with a demonstration of local song and dance by kids from the neighborhood, replete with drums and chanting. This dancing show gave me pangs, as in cultural experiences I’ve had elsewhere in Africa: I wondered if the kids participating in the show resented their elders for making them show off for the visitors, or if the joy on their faces during the dancing and singing was genuine, and whether they were grateful to share this expression and pride of culture. I hoped for the latter, as they did appear to be quite enjoying themselves. The smiles were genuine. Ours too.

Over the course of the 10 days, we learned, we did research drives, we walked along the white sand beaches of Kenton-on-Sea, and even did a night drive through the dirt roads we spent so many days travelling in our quest to find the herds. Jackals and kudu, white rhinos and rhinoceros beetles (one, landing on my neck, was an unwelcome visitor!)…and the Southern Cross in the Milky Way-spattered sky. But the highlight of the evening, as we were heading back to camp in the darkness, was a weird little creature we saw scampering down the dusty road, looking like a cross between a tiny bear and a marmot. He ducked down into a dry gully as we stopped, popping up only a metre away from the vehicle to stare down his smarmy nose at us. A honey badger! To quote even our naturalist, “I’ve never seen one of these in person before.”

We went up to Addo, a national park an hour away that boasts an elephant population of ~300. It’s rumored that a couple of Addo bulls are planned to be transferred to Kariega to help balance out and give some adult supervision maybe to a young and randy bull population over there (stay tuned, maybe that will be a new research opportunity!). The day was drizzly and spitty, but it was still fun to see dozens and dozens of eles at the different watering holes throughout the park.

It’s not without irony to me that there are really no wild wild animals remaining in South Africa. Their wild stocks have been poached and hunted to near-extinction; the wild lands, animals and all, are all now locked behind fences to protect them from the most alpha predator of all.

It was fitting, then, on our last day, that we spent time in the pouring rain visiting the APU, the Anti-Poaching Unit, at Kariega. These rangers steadfastly protect their eles and rhinos (black and white) from said predators. In fact, while visiting the team, we were privileged to a sighting of Thandi and two of her calves. Thandi is famous in these parts for being the only rhino to have survived a brutal poaching attempt in which two others in her crash (an apt collective noun for rhinos!) where brutally murdered. Thandi’s face was mauled when they hacked off her horn, but hers is a survival story that speaks to the valiant efforts of surgeons and conservationists alike to restore her face and her family. Since the poaching in 2012, she has created a small battalion of rhinos and now has grand-babies roaming the thicket and savannah of Kariega in her honour. On our first game drive, we met Colin, Thandi’s 2nd calf. According to Kariega’s website, that calf was named Colin in memory of the reserve’s founder, a man loved and admired by many, who had died just days before Thandi gave birth. The name Colin means ‘victory of the people’. White rhinos in this case.

The skies cleared just as we realised we were running late for lunch and our ride back to Port Elizabeth. We hadn’t managed to spot more than one or two elephants in the distance all day. But just like a cheesy movie, as we were losing hope, we managed to get a ping from Beauty’s collar – the one that had been malfunctioning all week. She was about a kilometer away from the fence at the edge of the Kariega Conservation Center. Of course she was. So as it turned out, in our last moments of our last game drive on our last day in Kariega, we were treated to a close encounter with the whole of Beauty’s herd, a brightening sky, and baked-in memories to last half a lifetime.

Late that night, in a hotel room in Cape Town, which felt like a million light years away from the reserve, I saw a WhatsApp message to our group from Brooke, the PhD researcher: “Beauty and Half Moon came up to the fence to say goodbye.” Later still: “Bukela’s herd crossed the river!” This was the exact thing we were there in South Africa to help observe: What happens when you remove a fence.

Next up: a few days in Cape Town and a long trip home.

I spent my holiday doing citizen science in South Africa: Part I

What draws us to elephants is a mystery. Or is it? They represent wisdom and strength and empathy. They are revered in Thailand and in India and elsewhere in Asia. Ganesh is the Hindu elephant god of new beginnings, the remover of obstacles and bringer of wisdom and luck. His name in Thailand is Phra Phikanet.

Across Asia and Africa, these magical and mystical creatures are worshipped in temples and simultaneously loathed in the fields, where their land is being encroached upon by farms and development. A mere “drive by” by a herd can decimate a family’s crops in minutes.

I think I’ve always been charmed by the magic of elephants, intrigued by their human-like behaviours, disgusted by humans’ treatment of them and their habitat. My first visit to Africa gave me a up-close look into those long-eyelashed orbs and I was smitten. It’s not a secret that Ganesh is something of my patron saint, and it’s certainly no surprise that I’m something of a wildlife freak. So when an opportunity to participate in Bring the Elephant Home’s volunteer program, assisting scientists with crucial behavioral research to learn more about social structure, welfare and habitat usage, I couldn’t apply fast enough.

Fast-forward 8 or 9 months, and I’m beginning to pen this on my flight home, coming down from the elephant high that has been my status quo for the last couple of weeks.

I joined the group in Port Elizabeth (recently renamed to Gqeberha), on the Eastern Cape of South Africa: a couple from the UK, a handful of Californians, and a student studying ele behaviour at a University in Johannesburg. From PE, we went up to our post at the Kariega Conservation Center at the Kariega Game Reserve. I posted a blog at the beginning of our time there called What Happens When You Drop a Fence, outlining our initial observations and the main research objectives.


What was it like?

So the 8 of us volunteers, 2 PhD researchers, and a local ecologist ventured out into the thicket of Kariega Game Reserve each day looking for elephants. While like something out of a dream, it also felt much harder than it seemed like it should have been. One might think elephants are so big, and how could you miss them, right? Well, crazy ele fact #1: they move silently. I mean, so silently that you could be sitting in a spot for a while and see or hear nothing, but a moment later, you could glance over your shoulder and see an animal the size of a Land Cruiser standing just metres away, trunk curled, sniffing in your general direction. While you’d think they’d make themselves known by heavy footsteps, their massive feet are so cushioned that they walk as if clad in slippers. In fact, more often than not, we’d know they were nearby only from the branches snapping rather than anything else (the tracking collars, when working, didn’t hurt either 😉).

Day 1

That first afternoon we went out on a game drive to get our sea legs, as it were… we saw zebra and white rhinos and giraffes and warthogs (Pumba!) and of course a few elephants. Even though it was just a couple of hours on the reserve, and we got a flat tire just before dusk and had to wait a while for another vehicle to come and bring us a spare and a new jack, it didn’t feel like a harbinger of doom for the week. Instead, it felt like the beginning of a cool adventure. Especially when I looked up and realised that the giraffes we had been watching on the other side of a hill began to creep in closer to get a peek at what we were up to out there in the scrubby thicket.

The first full day was a series of lectures on why we were there, classes on how to do elephant identification, exercises in what to look for, behaviour-wise, and a slew of what to do when things around age and sex and different behaviours and dung sampling and using the Zoomonitor app to record said behaviours. It felt like a lot.

I mentioned to my manager that we had elephant school that first day. He replied that he had heard they are good learners. Us humans, though… the jury was still out.

One of the first lessons was ageing elephants. It’s done by relative size, facial features, and behavioral characteristics. Calves (<1) can walk underneath an adult cow. Juveniles (1-4) are still suckling but may or may not have tusk buds (squeee!!!). While Intermediates (5-8) may or may not look like sub-adults (9-15), they are weaned and the females take on more and more “big sister” duties. Sub-adult bulls spend less and less time in the center of the herd as they mature and become more independent (and, you know, more like naughty teenage boys!). Adults (15 and up) come in different shapes and sizes, depending on whether they are bull or cow. I learnt so much just this first day on these different stages, not least that bulls don’t even come into their first musth until they are about 25, while cows can start having their own calves by about 11.

Once we had a decent grasp on ageing, we moved on to sexing (size, head shape, body configuration, rear view). About half-way through this lesson I felt like I might fail elephant school altogether, so I was glad that the professionals would be with us in the vehicle to help out with our ID follies!

The team uses the SEEK (System for Elephant Ear Knowledge) system which incorporates a set of features and markings in addition to body condition on a scale from 1 (emaciated) to 5 (chubbo) to identify and code the targets of our observations. I’m grateful for the visual aids we were given, as well as the Elephant Voices ethogram website which we were encouraged to review prior to arriving. This was beginning to feel like work.


The last part of our training day was to review the different behaviours we were to observe and track: continuous behaviours like locomotion, grazing, browsing (and identifying the differences therein), and all-occurrence behaviours like head shake, sniff, play spar, trunk curl, trunk to face (and whose trunk to or from whose face)… again I was appreciative of the technology at hand – the app into which we were to record said behaviours and the myriad PowerPoint decks and references that had been prepared for us novices.

As the long day wound down, we received our marching orders: review the materials and get ready for an early wake up call. We were going into the field in the morning, then breaking up into groups of 3, one to observe behaviour, one to do elephant ID, and one to be the photographer.

One can only guess which role I was more than glad to take on.

Stay tuned for more adventures from a citizen-scientist perspective. And be sure to take a look at Bring the Elephant Home’s updates page for more stories from our time at Kariega.

What happens when you drop a fence: 5 observations.

Big news at Kariega Game Reserve! In December of 2023, in association with the Kariega Foundation’s habitat expansion project, BTEH supports the removal of one of the internal fences connecting the Kariega West and Harvestvale areas of the park. A key mission of the project is to give herds on opposite sides of the fence (and river) access to a broader habitat. I mean, who wouldn’t want a larger area in which to play and explore? One of BTEH research objectives is to see, in short, what happens when you remove fences and how that impacts herd behaviour and population health.

I’m reporting from the BTEH elephant research program at Kariega, March 2024. This is the first time BTEH researchers Brooke Friswold (PhD student) and Antoinette van de Water (PhD) have observed the different herds here post-fence removal. It’s an exciting time to be a part of this! [Aside: if you’ve always wondered how to get involved with elephants, are a little nerdy about research stuff, and think the idea of a safari seems a little too much like a canned experience, you’ve got to try this program! 😉]

Here are 5 observations (expected and otherwise) after fence removal:

New places to explore!
Not surprisingly, we’re already seeing herds and individuals that were once confined to the Kariega West area exploring into the Harvestvale section, and vice-versa. Elephant location, movement and interaction are monitored via GIS (geographic information systems) tracking and low range radio collars which were fitted to 6 elephants of varying ages/sexes in August of 2022. Fitting collars is a complicated and costly operation, requiring veterinarians, helicopters and scientists (plus some luck), so it was devastating to learn that more than half of the collars have failed (full collaring report here) due to twisting and malfunction. The elephants are fine, but the science is impacted. Findings during our time here in March will assist with on-the-ground identification, behaviour tracking, and dung sampling (yep!).

You see Brooke tracking Beauty’s herd via a telemetry antenna contraption in the pictures above because a 4th of the 6 radio collars is malfunctioning.

The bulls are a little, erm, randy.
Think of it like spring break: you put a bunch of single college guys in a new environment with a bunch of cute and possibly available chiquitas, what do you get? Well, scientifically, many of the males (bulls) have gone into musth, or a state of pre-musth (though per the science-y folks, this observation is still anecdotal but we found out this week that there are 3 (!!!) bulls in musth right now here at Kariega). In general musth is a stage of the mating cycle when adult or sub-adult bulls experience testosterone levels of 60 times greater than average. This makes them do weird and not-so-weird things like Following sub-adult females (cows), Touching genitals (their own and cows’), placing their “Trunk over back” of desirable cows, chasing zebras, walking around Sniffing the air, wandering far and wide, and generally getting excited for the “new meat” in the vicinity. We’ve observed and logged many of these behaviors in the Zoomonitor app, and we’ll see how this plays out (stay tuned to the BTEH updates page for details).

Amazing social excitement and interaction.
In our first days of observation here, we noticed some of the Kariega West and Harvestvale herds have meshed. Our first morning, we saw the Half Moon herd mix with Beauty’s herd. This of course throws off the ID database, which had neatly arranged individuals by herd by area, and means that our ID work this month will be crucial to not only identifying individual cows and bulls assimilating into different herds, but also tracking the potential new herds that may form as a result (see point 2). Per Antoinette, “It’s amazing to observe elephants that fully have the freedom to explore and interact and make new social connections. This is the best way to see elephants completely in their element.

  • a herd of elephants in Kariega Game Reserve

Some are travellers, some are not.
Kariega’s elephant population is roughly 75 individuals. Elephants are social and highly intelligent: emotionally and mentally. They are said to never forget, and can hold onto traumas just like people. Herds are traditionally led by an old and wise female (I began writing this post on International Women’s Day, so of course they are 😉) So with all the exploring and commingling some of the elephants are doing, one matriarch, Bukele has still not crossed the river from Kariega West to Harvestvale. Whether it is because the way to the other side is around or that the river is saltwater and thus creates a natural fence (elephants love to swim and bathe, but prefer freshwater), this remains to be seen. Camera traps, GIS tracking, and future research trips will help answer these questions…and more.

Happiness is contagious.
During our initial drives, we observed un-stressed, curious, social, and thriving elephants. As with humans, lack of stress reduces cortisol, which leads to overall better health and well-being. Additionally, seeing happy and healthy elephants put a smile on the face of everyone in our vehicle. Per Antoinette, “What we observed yesterday is like the best example of how range expansion contributes to animal well-being.” When elephants are happy, so are the people watching them. Want to learn more?

When I asked Brooke what her biggest surprise was, she commented that it is so exciting to see the different herds socialising and commingling like this. “It remains to be seen,” she said, “whether this is just exploratory because it’s new, if the new commingled herds and interactions will persist, or if they will go back to their original structures in time.”
