Meredith has been busy this past week attending the Citizen Science conference in St Paul, Minnesota. She reports back that it was a fantastically stimulating conference that confirms the high esteem that citizen science has grown within the science community.

 

The yearly conference sees a diverse group of people from researchers, educators and universities to the likes of NGO’s and museums get together to discuss the use and promotion of citizen science. Although we at Snapshot Serengeti have been aware of its great impact for some time citizen science is now emerging and is recognised as a powerful tool in the advancement of research by many.

 

Those attending the four day event collaborated by sharing their varied experience and ideas on a variety of topics. The collection and sharing of data and how to impact policy was discussed. There was focus on how to use citizen science as an engaging teaching tool, how to bring citizen science to a wider audience and how to involve citizens more in research. Those attending brought their joint experience and expertise together to discuss how citizen science impact on science could be measured and evaluated.

We sometimes forget when working away at classifying our stunning images on Snapshot Serengeti that there is a lot of tech going on that enables us citizen scientists to be of use to the scientists. Meredith gave what’s known as a ‘project slam’ essentially a 5 minute presentation about our work on Snapshot Serengeti  and how it has paved the way for helping other cameratrap citizen science projects. A quick look around Zooniverse will show just how many there are now.

 

The massive amount of data produced over several seasons through Snapshot Serengeti have allowed the development of a robust, tried and tested methodology that smaller projects would have taken years longer to develop. Just contemplate the work that went into developing interfaces, protocols, pipelines and algorithms for taking millions of classifications of untrained volunteers and turning them into a dataset which has been verified to be >97% accurate.

It is awesome to see that something we all find so truly engaging can translate into such serious stuff in the field of science. I think we, the citizen scientists, and the Snapshot team can be rightly proud of our work on this brand new branch of science

A Green Desert

I have to admit that I actually quite like insects, they fascinate me, they are often brilliantly coloured and despite being so small seem to send most humans into a frenzy of panic. It astonishes me that these tiny creatures can come in such an array of beauty; something about the miniature form is beguiling. How can so much colour and pattern fit on such a small form.

However there are insects that do not elicit these feelings of wonder. Mosquitoes for one and ticks; both are annoying and can have you in your sick bed. If you have ever been hounded by sweat bees that want to crawl into every corner of your scalp, eyes, nose, ears and mouth you will know what I am talking about when I say they are enough to make you want to dive into a shark infested pool.

But… there is one creature that for me is worse than any of these, one that I cannot tolerate either mentally or physically. The tsetse fly.

My first encounter with tsetse in Central Africa has left me somewhat traumatised. I set off from base camp on a 2hr drive to an old abandoned camp to scavenge some equipment. The car had seen better days and although it had a windscreen it did not have windows. Lovely I thought, it’s hot and it will be nice and airy. The roads were in a bad state, necessitating a top speed of around 30km/hr. The first few km’s were fine then something sharp bit my ankle. Following that the same burning sensation came from my neck then there it was again from my shin instantaneously reappearing, most painfully of all on my temple. I looked around the dash board and it was swarming with about 50 tsetses all of which were clamouring to get to my bare skin and feast on me. They had been sucked through the nonexistent windows and there was nothing I could do to keep them out. All I could do was hold my collar closed whilst driving one handed the rest of the way. By the time I arrived I had welts all over my hands, neck, legs and feet. Yes they had actually crawled into my socks to get at my nice hot blood filled feet. Aarrrrrhhh.

Discomfort aside there is a very real risk to tsetse. They are vectors for a debilitating disease, sleeping sickness medically known as trypanosomosis. The disease effects both wild and domestic animals and humans. Whilst wild animals have a tolerance to the disease cattle do not. 3 million are thought to die a year across sub-Saharan Africa. Sleeping sickness in humans is often fatal if not treated although the death rate has been vastly reduced with modern medicines.

Historically areas of intense tsetse fly activity were not cultivated by humans leaving large fertile areas of the African continent as so called green deserts. Although a terrible burden for the human population it was good news for wild animals. The area of Central African Republic where I worked was one such place. It should have been teaming with wildlife but it wasn’t. In fact it was full of cattle during the dry season. The cattle herders are arriving in ever increasing numbers from Sudan trying to find respite from the desertification of their own lands.  So how can this be? How can they survive the obvious tsetse infestation?  It is all down drugs and motivation. The cattle must be shot full of drugs in order to survive the tsetse. A lot of these drugs are supplied by aid agencies trying to stop the human crisis developing but this inadvertently turns into a wildlife crisis. Not only do the herders now spend 4 months a year with their cattle competing alongside wildlife for resources but the herders are decimating the wildlife through poaching. They kill as much as they can, drying it to take back to Sudan and sell. It has become a major trade route and next to the armed gangs who extort protection from the families of herders the next richest guys working the route are the medicine sellers. Without the medicine the cattle die and the whole thing collapses.

Depressing I know but it does put the tsetse in context. Perhaps they played a very important role limiting the use of fertile land by over consumptive mammals. Once I learned their role in keeping humans out of wilderness areas I was a little more forgiving of their painful bites. Though when you have hundreds of bites all over you there is always that niggling worry of illness. Thankfully I escaped with nothing more than some ugly, very itchy swellings and a new understanding of the complexities involved with wildlife conservation.

Snapshots From The Past

 

This weeks guest blog is from our moderator David Bygott who has been guiding us through Snapshot Serengeti images since the beginning.

 

I’ve been lurking here for years as a moderator, but Lucy Hughes invited me to come out of the shadows and tell you how I got my Serengeti creds.

As a country boy in England I was obsessed with nature and yearned to see more of the world’s wildlife. Reading “Serengeti Shall Not Die” by Bernard Grzimek, inspired me to go there. The dream took some years to achieve. First, I worked hard to get a zoology degree. Then, I wrote to anybody doing field research in Africa who might need a research student, assistant, or slave. I got lucky. A scientist, studying hyenas and wild dogs in Ngorongoro Conservation area, wanted me to work on her better-known chimpanzee project, which I had been following in the pages of ‘National Geographic’. Sounded good.

Thus in 1969 I pitched up at the camp of my new bosses, on the floor of Ngorongoro Crater. Ten days of getting to know Jane Goodall and her photographer husband Hugo van Lawick, and total immersion in African wildlife. Incredible nights of watching hyena packs run down wildebeest and tear them apart. Even a road trip into the heart of Serengeti.

A seed sown, my mind blown, I continued across Tanzania to the remote chimp camp at Gombe National Park on the beautiful forested shore of Lake Tanganyika. Here I spent 2 amazing years with a small team of young people, following the famous chimps through the forest and recording their behavior. Experiencing at first hand our closest kin was a life-changing experience for me.

While at Gombe, I met more of my scientific heroes. Bernard Grzimek visited, so did Dian Fossey, and I travelled to Rwanda to see her gorillas. Jane’s doctoral advisor Robert Hinde came, and encouraged me to write up my fieldwork for a Cambridge PhD.

Two unexpected things happened at Cambridge. I met my wife, primatologist Jeannette Hanby. And we got to know Brian Bertram who had studied Serengeti lions for 4 years, following George Schaller’s pioneering work. Brian persuaded us that social carnivores were just as interesting as primates, and that there was still more to learn about lions. It was a change of direction, but we were tempted!

So in 1974 we joined the Serengeti Research Institute as lion biologists, thanks to support from the U of Cambridge. Our main mission was to census the lion population, as National Parks feared that lions were decreasing (they weren’t!). We also compared the lives of lions in different habitats (Serengeti Plains where prey abundance is seasonal, and Ngorongoro Crater where prey is always abundant). And we investigated lion pride dynamics – why do some individuals leave, and others stay?

Imagine being part of a community of scientists studying every aspect of the ecosystem. We had a house in the centre of Serengeti and a Land-rover to go wherever we wanted, and we spent our days and nights with the great tawny cats.

Sometimes humans and lions are attracted to the same campsites

 

It was remote, but fortunately we were both used to that. Every month we made a supply run – either to Arusha or Nairobi, each at least 200 miles away, mostly on dirt roads. This took 2 days each way, plus several days of shopping and socializing. We learnt a lot about fixing cars, often in beautiful remote settings with primitive tools.

 

 

 There was much less technology then. We had basic maps but no GPS, radio or mobile phones or internet. There were no computers, though we had cutting-edge hand-calculators. Radio-telemetry was in its infancy; we built our own radio-collars and darted and collared a few lions, but for most of our study we had no air support and ground-to-ground range was poor, so we had to rely on careful searching to find the lions – scanning with binoculars, driving, staying out at night to listen for roars. We identified the lions from natural markings and close-up photographs, on film of course. We developed a symbiosis with cheetah biologists, George and Lory Frame, photographing each others’ study animals whenever we saw them and trading ID photos to increase our sightings. We learnt as much as we could about what all our colleagues were doing, and often participated in ecosystem-wide aerial animal censuses.

We tried various methods of counting lions, including aerial and ground transects and individual recognition. The latter proved the most successful, but it was hard work to identify all the lions in our 1000 square study area. In addition, every second month we’d spend a week in Ngorongoro Crater. After finding as many lions as we could there, we would follow one pride for 4 days and nights, to observe their activity, range and hunting success. We did the same with a comparable pride living at Sametu on the Serengeti Plain. The story of the Sametu pride unrolled like a soap opera, and we couldn’t resist writing a book about them. “Lions Share” tells their story, but also incorporates much of what we knew about lion behavior and about the ecology of Serengeti. (Out of print, but look on Amazon).

Eventually we had to leave, and our friends Craig Packer and Anne Pusey took over the Serengeti Lion Project. Craig amazingly kept it going from 1978 to 2014, and Snapshot Serengeti is an offshoot of what has become one of the world’s longest running wildlife studies.

After writing up our 4 years of lion data, we returned to Tanzania in 1982 to work in conservation education; university teaching, producing guidebooks and interpretive displays, and guiding safaris. We built our home near Lake Eyasi, and experienced years of village life and culture clash, but that’s another story (in preparation). In 2003 we moved to Tucson, Arizona, but I still get back to Tanzania every year, mostly leading National Geographic Expeditions.

I’m organizing my own safari to visit Serengeti and other parks in February 2018. If you seriously want to see these wonderful animals in the flesh, send me a message!

Save The Rhino Day

Today’s blog is by Sarah Huebner, a first year PhD student at University of Minnesota’s Lionlab studying under Dr Craig Packer. She writes about Save the Rhino day that was celebrated this week.

May 1st, 2017 is Save the Rhino Day, a day on which we must ponder what can be done to pull this beautiful animal back from the brink of total destruction. With fewer than 25,000 rhinos remaining in Africa, there is a strong possibility that they could go extinct within our lifetimes if poaching continues at its current pace. In addition to the problems of habitat fragmentation and human-wildlife conflict that all African animals face, rhinos have a target on their backs from poachers and criminal elements seeking to profit from selling their horns.

There are two species of rhinoceros in Africa–black rhinos and white rhinos. Both black and white rhinos have two horns on their heads, a larger one in front and a shorter one behind it. It is estimated that there are only 5,000 black rhinos remaining, down from 850,000 in the mid-20th century. The reason for this dramatic population collapse is poaching and sale of their horns through a criminal network from Africa to Asia. Though the rhino was added to the CITES list of animals banned from trade in 1977, their numbers have continued to crash since then. This is primarily due to the demand in China, Vietnam, and North Korea for use of the horns in jewelry, carvings, as a status symbol, and even in medicine. Some people believe that rhino horn can cure cancer. Scientific evidence clearly shows that rhino horn, made from the same material as our fingernails, is not at all useful in medicine.

Perhaps most distressing is the news that the ban on rhino horn trade in South Africa, home to the largest extant population of rhinos, has been lifted by their court system, clearing the way for the legal export of rhino horns. This does not mean that illegal trade will cease. Indeed, this move gives even more cover to the criminals trafficking rhinos. Though rhinos have the ability to regrow their horns, most are killed before having their horns sawed off, as we saw in the horrifying incident at a French zoo recently. If the rhinos are still alive when the horns are removed, they suffer terrible pain and are left to die, which many do because of blood loss. Impoverished poachers in Africa make very little for their efforts, while importers and sellers in Asia can make as much as US$30,000 for one kilogram of horn. Some estimate that the sale of both the front and back horns together is worth US$250,000. This makes rhino horn more valuable than gold or platinum. Little wonder that private reserves in South Africa wish to profit from the sale of these animals’ parts.

How then do we stop this? Organizations such as the Wildlife Justice Commission and Outraged South Africa Citizens Against Poaching are working to expose the criminal networks responsible for the poaching, smuggling, and selling of these horns in Asia. We can aid these and other conservation groups by helping to finance their initiatives designed to curb poaching. Perhaps the best way we can take action is to pressure our own governments to enact diplomatic sanctions on the countries that continue to look the other way while rhino horns are smuggled across their borders–primarily China, Vietnam, and North Korea. Diplomatic acts such as sanctions, travel bans, and blacklisting by other countries could convince these governments to enforce the national and global laws already on the books concerning rhino horn. On Save the Rhino Day 2017, contact your representatives and tell them that you want them to use diplomatic methods to pressure these countries to stop the import of rhino horn. Or the only way our children and grandchildren will see rhinoceros is in pictures, as we tell them about the magnificent creatures that once walked the earth.

Remote Places

One of the reasons I love working in conservation is the remote places it brings you to sometimes. Although born in London I am not a city person and haven’t lived in something even as big as a town in around 20 years. I am happiest wandering around in the bush observing animals in all their splendour without the addition of people.

So believe me when I tell you that my assignment in Chinko nature reserve was remote.

To get there you take a 2hr 30 min flight by light aircraft from Bangui, the capital for nearly 1000km. Of course you could drive if you have the time and a strong sense of adventure, the roads, however are impassable in the wet season. Road blocks are rife in a country where ethnic tensions are high. The route takes you through towns that only UN convoys dare try and pass.

The last half hour or so you are actually flying over the reserve itself. At 17,600 sq km it is enormous. There are no settlements in the reserve boundaries and the nearest village, Bakouma, is a bone shattering 12 hour drive away that includes a ‘ferry’ across a wide river. This is the nearest place for any supplies and also where most of the staff comes from. Bearing in mind that again this road is all but impassable during the 5 month rainy season when mud can mean it takes three hours to drive 5 km. Watching the plane trundle down the dirt runway as you stand there with your bags can insight a momentary sense of panic in many first time visitors here.

Of course getting there is not the only problem. Moving around the reserve is just as difficult. The habitat is a mosaic of tropical lowland rainforest and forested savannah which translates to very tall grasses and many rivers with thick tangled vegetation, not at all easy to drive through let alone walk through.

 

On one occasion I set out with the resident biologist to put out camera-traps. We drove all morning, checking for likely spots. Around midday we had to ford yet another river; as the car gingerly entered the water it suddenly slew to the left and sank notably. We were stuck and guess what? we had been assigned a car with a winch that did not work.  After an agonising hour or two trying to get ourselves unstuck Thierry decided it was time to call in a rescue only to find his sat phone was having network issues. There was nothing left for us to do but start walking. It would be a 25km walk back to base, with all the streams and rivers water at least was no issue.

As we had no choice but to walk, Thierry, ever resourceful, suggested we treat it as one very long transect and record all that we saw along the way. It certainly kept my mind off the heat and dust anyway. How wonderful to just walk and see no signs of humans anywhere, only nature. It was better than being in the car where you heard nothing over the engine. Somewhere out in the middle of that walk we stumbled on a massive sinkhole about 30 meters deep and 50 meters diameter. Buzzing all around was a large colony of red-throated bee-eaters, not known to breed in Central African Republic these birds had obviously not read the books because they were flitting in and out of nest holes in the walls of the sinkhole.  As we watched the show the bee-eaters put on for us I reflected that perhaps we were the only humans, certainly in recent history to have observed this spot buried deep within a very large isolated corner of  Africa. It is a humbling experience to discover nature in its undisturbed state and I never tired of exploring Chinko’s river systems and forest clearings. Stumbling upon giant trees or ancient salt licks carved by forest elephants or just watching troops of monkeys and flocks of hornbills passing through the canopy above was manna for the soul.

As we approached base camp and the noise of industry kicked in, generators, cars, people, I had to mentally re-adjust bolstering my courage to deal with everyday camp life again thankful that something as simple as a stuck car could have afforded me a little more time cocooned from the real world.

The biggest tree roots ever

The Square

So you probably know by now that season 10 is up and running and there have been some amazing camera-trap images uncovered already. As well as a few lounging lions and wandering wildebeest there have been some stunning aardvark and wildcat images.

This season has turned up quite a few images with a central square that is brighter than the rest of the frame with a luminous look. These somewhat Warholesque images look as though they have been photo-shopped and I love them. Here are just a few. My favourite is the zebra, its perfect.

Obviously these are not some new form of art but have a more down to earth source; a malfunction with one of the camera trap types. A patch provided by the manufacturer restores the image to normal which for scientific purposes is very good but from the purely aesthetic side its kind of sad, I like “The Square”

 

 

Topi versus Hartebeest

Here is another pair of antelope that are often muddled up on Snapshot Serengeti; topi and hartebeest. These two share a similar size and body shape and for those of you not familiar with them they can prove a bit tricky.

Topi and hartebeest belong to the same tribe, Alcelaphini, which also includes wildebeest. These antelope typically have an elongated face, long legs, short necks and stocky bodies. Although these antelope have reasonably large bodies their long legs mean they have retained the ability to run fast, a good adaptation for life on the open plains. It is believed that the long face developed in place of a long neck in order to reach the grasses they consume.

There are several species of both topi and hartebeest in Africa, two are found in the Serengeti. Coke’s hartebeest or kongoni (Alcelaphus cokii) are selective grazers with browse making up less than 4% of their diet. Serengeti topi (Damaliscus jimela) are 100% grazers

In both species males are territorial but topi also form leks from which to display to passing females. Males holding territory close to the lek are more desirable to females. Dominant females will actively prevent subordinate females from mating with these males.

 

Topi                                                         Hartebeest

So side by side we can see that the topi is much darker coloured than the hartebeest with distinct sandy socks up to its knees and conspicuous black patches on the thighs and shoulders. In contrast the hartebeest has pale legs and underbelly with a darker upper body. The paleness forms a patch on the top of the thigh.

 

Topi                                                                        Hartebeest

From behind the contrast between leg colour and backside is very obvious with topi sporting dark legs with pale rump and back and hartebeest pale legs and rump with dark back.

Horn shape is also different. A topi’s horns sweep up and back whereas a heartebeest’s sweep out to the side before kinking back. They also sit on a prominent bony ridge on the top of the head.

Hopefully this will help you tackle all the images waiting on season 10.

Grant’s Verses Thomson’s Gazelle

 

The Zooniverse team are super busy at the moment but hopefully very soon season 10 will be loaded and we can all get cracking with what promises to be a fantastic season full of amazing images.

In the meantime I thought I would post a few notes on those tricky animal pairings that seem to have more than a few people stumped when trying to id them.

To kick it off we will look at Grant’s gazelle and Thomson’s gazelle. If you were treated to perfect photos every time I think you would get the hang of these two pretty quick but with the often blurry or distant images we get on snapshot they can be tricky.

 

Grant’s gazelle A                        Thomson’s gazelle A

 

A; First off there is the overall colouration. Thomson’s has a thick dark stripe across its side, Grant’s usually lacks this but be aware as some Grant’s have a dark stripe too. Not the best distinguishing feature as there can be quite a bit of colour variation.

 

Grant’s gazelle B                          Thomson’s gazelle B

 

B; A better distinction is the facial markings. Grant’s gazelle has a thick black stripe running along the side of the face from the nose passing through the eye to the base of the horns giving a masked look. Thomson’s has the same stripe but it ends at the eye, not passing through. The white band on top of the black stripe is more distinct on Grant’s.

 

Grant’s gazelle C                                  Thomson’s gazelle C

 

C; If you get a back-side shot then Grant’s displays a much whiter overall appearance with the white area extending past the root of the tail up onto the back. In Thomson’s the white area stops at the root of the tail. Grant’s tail is white at the root and thin with whispy black end, Thomson’s is dark and fluffy looking. The black vertical bands in Grant’s are also more prominent.

 

Grant’s and Thomson’s Gazelle

In a mixed group the smaller size of Thomson’s is evident, although with young animals it is not so obvious.  Here you can easily see most of the features discussed above with the Grant’s gazelle comprising the 7 animals to the right back and the Thomson’s gazelle to the left forward. Note the Grant’s gazelle side on at the back, it shows a much darker side stripe than the others more a kin to Thomson’s. Males and females of both antelope have horns with the females usually shorter and thinner. In some females horns are absent. In general Grant’s are more graceful looking than the stocky Thomson’s.

 

 

The River

The Oliphants River

 

Now that we have finished classifying season 9.5 and we have a short break before season 10 is launched I thought I would muse a little on my favourite wildlife setting; Rivers.

I live in South West France next to a river. Its gentle passage demands my attention constantly. That’s because rivers are magnets to wildlife. Everything needs water to drink and in a dry area it means your best chance at seeing wildlife as they come to drink.

In Africa too, I lived by a river and what a special place that was. The Oliphants, sometimes a trickle sometimes a violent torrent, flows into Kruger National Park and I was lucky enough to live on its banks for 4 years. I could watch the daily spectacle of life unfold from my stoop. I watched baboon troops clash viciously, hippo’s endlessly dose, leopards stroll the beaches, fish eagles catching supper. I once watched a four meter long rock python ascend the cliffs opposite effortlessly and I followed the progress of a family of spotted eagle owls on a nest in a crevice, worrying absurdly when the river began to turn chocolaty and rise. They survived but I was ready to brave crocs and hippos and swim over to rescue them.

You can watch for hours and see nothing then turn your back for a second and suddenly 5 kudu have appeared out of nowhere. One early evening I sat watching, all was quiet except the birds calling in the bushes. It was approaching the hour that nightjars start to sing. All of a sudden the shrill nasal alarm snort of a Klipspringer rang out quickly followed by the outraged screaming of vervet monkeys. Grabbing binoculars I focused on a blur on the rocks opposite in time to see a klipspringer launch itself off landing with an almighty splash in the river. A leopard came to a screeching halt on the rocks not wishing for a swim. The river meanwhile was flowing pretty fast and I thought the klipspringer, more suited to rocky precipices than water, would drown.  Amazingly the stout little antelope managed to swim to the shore and clamber out, shaken no doubt but alive. I often wondered if he ever made it back to his side of the river.

A stroll down the beach was always an education. The damp morning sand would show who had passed previously and was great for practicing tracking skills. On one such stroll I noted an absence of leopard tracks on my outward walk only to discover on my return journey that a leopard had left its mark on top of my foot prints; a little disconcerting.

The river, for most of the year, retreated to the deeper channels leaving a boulder strewn sandy beach lined with large trees such as sycamore figs and marulas. During the driest part of the year we really felt our connection to the great Kruger Park. Our reserve was quite small by African standards and did not have elephant or lion resident but during the dry period elephant would take to wandering the river course right out of the park and would spend a few weeks looking for food on our reserve before wandering back to the park. Lion too followed this same route and it was always a thrill to double take on a seemingly large leopard print only to realise it was in fact a lion.

The other end of the scale came with the rains. The river could rise meters in minutes turning a deep chocolate brown. The force of its passage was astonishing, great trees would be swept down, I have seen cars and sofas swirl by. Most of the animals that live in the water seem to get out whist the storm passes but I watched a hippo once in the full force of the raging river and I suspect that it wasn’t by choice that he was in there that somehow he couldn’t get out.

So benign or raging, highway or refuge the river is like an anchor to wildlife. The chance of seeing wildlife there is strong but even if you don’t they are intrinsically beautiful places.

Field Life

Nzunda setting up a weather station

 

 

Recently, as those of you who follow will know, I have been talking about the different people who work for the project in Tanzania. Reading about their daily lives working in ecology and conservation is about as close to visiting Africa as many of us will get. Their lives seem so fascinating I think because they are so different to most of ours (though that is a bit of an assumption of course!)

I talked to Ozward Nzunda, one of Dr Michael Andersons Tanzanian field assistants in the Serengeti. Michael’s project looks at vegetation and the interactions between herbivores and their savannah habitat. In order to study this a wealth of environmental data is needed and of course Michael, like many professors, is not based in the Serengeti. He relies on Nzunda to keep things running whilst he is not there. I asked Nzunda about his work and what it was like living in the famous Serengeti National Park.

He told me that most of his work in the field involves the collection of data from all over the study area. There are camera-traps that are checked once a month in order to down load the data and check for any maintenance issues. This is the data which we are busy classifying now on season 9.5. He must also collect weather and soil moisture data on a monthly basis in preset locations. He has to install the weather stations and soil moisture sensors and keep monitoring them until the data is collected. These jobs take up most of his time but he also has the unenviable job of keeping the project vehicles running. Tree and seedling surveys are done on a yearly basis.

So how does he manage all this and what does he think about it?

He told me that the days are long in the field, the drive to the study plots is long and so a lot of time is spent in cars and when you get to the study plots there is a chance you won’t be able to get out the car to do anything. Many a time he says, he has arrived to find lion sleeping or with a kill near his plot and is forced to wait for the lions to leave or move on to another plot. Of course so much time in the field also means he gets to enjoy seeing lots of game on a regular basis.

The study is a continuous study and that means that the data must be collected come rain or shine and in the wet season that means mud. Nzunda told me that the hardest part of the job is wet season driving when you can easily get stuck in the black cotton soils. The mobile signal is poor, as you can imagine, in the park and he has been forced to sleep in the car on occasions until help arrives the following day.

In fact he says they regularly camp out in order to visit the remoter plots and has some interesting stories to tell. Camping in an area with a full complement of wild animals is not for sissies! But on this particular occasion it was the ants that kept them awake. A swarm of biting ants invaded the campsite and had them jumping up and down, shaking out clothes and acting like mad men until they finally left. Itching and scratching they finally got to sleep only to be woken up a few hours later by a rampaging hippo careening between their two tents. Now a canvas tent is no match for a hippo but luck was on their side and the hippo kept running and didn’t return. He says he will never forget this night and they named the campsite “one eye open and one eye close” in honour of the fact no one really slept that night.

His family and friends think he is mad for working alongside wild animals, they think only of the risks but Nzunda loves the challenges field work brings and says that the Serengeti is a beautiful place to be.

Life in the field can be a little lonely. His family live almost 1000km away and he only see’s them about once a month if he is lucky. But they are all accepting of this and are happy. A good job is worth it. He prefers the park saying it is a very good place to live, far better than town where there is too much noise and pollution. He gets his fill of social once a month when he leaves the park to go on a shopping trip for supplies. The rest of the time there is a small shop that caters for the parks staff and resident researchers and the little community gets by fine.
