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.

Dante’s Inferno; Savannah Fire

 

l1040443

 

Fire ecology is a fascinating subject. I always get a bit of a buzz when I find a fire image in Snapshot Serengeti. Fire is a major component of savannah ecosystems and the grasses and trees within them have evolved along with fire, some to such an extent that they cannot exist without the occasional burn. I will return to this topic in a future blog but for this week I want to recount my personal experiences of the fire season in a remote Central African nature reserve.

As the dry season progresses the deep verdant greens start to fade to yellow, the temperature mounts into the high 30’s and the strong Harmattan winds pick up. The landscape is a mosaic of tall savannah grasslands divided by fingers of thick lush riverine habitat. The climatic conditions bring violent lightning storms which, given the tinder dry grasses, can trigger natural bush fires. Of course this process is random, not every patch of grass will burn every year unlike the human induced fires that sweep this part of Central African Republic year after year.

Historically this area saw very little pastoralist activity due to the tsetse fly (lethal for cattle) but in recent years Sudanese cattle herders are flocking to the area during the dry season driven by increasing desertification in Sudan and availability of medicine to combat the effects of tsetse fly for their cattle. They set light to every bit of grassland in order to make movement easier creating a green flush for their cattle to feed on and to make hunting for bush meat simpler.

Each day our plane goes up searching for signs of the approaching herders. We all anxiously scan the horizon for signs of smoke. The weeks drag on like this with everyone under a nervous tension waiting, waiting for something to happen. One day the pilot returns having spotted a huge fire to the north and just like that it has started. Every flight brings more fire reports and we see a daunting change in the clearness of the air around us. Sitting in the central base looking at the fire map it seems we are now surrounded by either fires or herds of cattle numbering in the thousands. With the scent of scorched vegetation getting stronger by the day things start to feel very claustrophobic.

By night we see an ominous glow to the horizon as the distant fires glow and we dread the change of wind that could bring the wall of flames towards camp. We have a wide airstrip almost a kilometre long so I know that we will not be in danger of being burnt alive but it does not quell the primal fear.

The day I have been dreading finally comes. Fire is spotted 5km from the camp and it is racing towards our fire break, a team rushes out to light a back burn to try and stop it in its tracks but the wind does us no favours and within hours we can see the flames as they burn behind the camp perimeter. I am feeling panicky but although it looks like Dante’s inferno the danger has passed as the fire makes its way along the north side of the airstrip. Then disaster strikes the wind, capricious as ever, changes direction just as the fire reaches the end of the airstrip and a great gust of hot ash and embers jumps the fire break and the fire starts racing up the south side of the airstrip. And all hell breaks loose; we never expected it to get into this block. The fire is now making a bee line for our temporary accommodation camp and my own tent. Never have I run so fast, 400 meter sprint in 40 degrees heat in a herculean effort to reach my tent and evacuate my worldly goods. I wrench open the canvas and start madly flinging stuff into bags, meanwhile some clever person arrives with a wheel barrow and we start moving the bags to the safety of the airstrip.

Once everything is safe I sit down and watch the chaos from atop my possessions. It is a scene out of apocalypse now. There is a helicopter and cargo plane belonging to the American Special Forces grounded on the airstrip. Smoke rises in front of me like a billowing curtain, our staff are running around beating out flames as they try to control the back burn. In the midst of this someone brings me a very angry chameleon, rescued from the path of the flames. There are gun shots ringing out from the Ugandan army camp who, instead of helping us, are trying to shoot rabbits and other small game as they dart from the onslaught of flames. Our guys win the battle and the fire comes to a slow stop just 70 meters from my tent. My heart has calmed down now but it is with sadness that I look around me at the blackened ground. I wonder how many chameleons and other small creatures lost their lives in this battle.

That night I slept once more in my tent. I lay there watching the beautiful glow of the fire through the trees, looking just like a glowing sunset. The spitting of flames and the cracking of exploding trees reminding me of the truth but the fire was on the other side of the strip of riverine trees and I knew its rich damp interior would keep me safe as well as countless other birds and animals that night.

In my last blog I mentioned Ingela Jansson and the KopeLion project and promised to tell you more.

Ingela spent three years working for the Serengeti Lion project as a research assistant monitoring lions in the Serengeti National Park as well as the Ngorongoro Crater. Although working in the park was an amazing experience it was the work she did in the crater area that was to prove a more urgent calling. The very real conflict she saw between humans and lions persuaded her that if someone didn’t do something the Ngorongoro lions were headed towards extinction. And so KopeLion project was born in 2011.

The Ngorongoro conservation area was gazetted in 1959 and designated a multi use landscape. The pastoralist population were permitted to continue living there alongside the wildlife. Since this time the population has risen 10 fold and the once harmonious coexistence with lions has collapsed. Lions have disappeared from much of the area and the connection to the Serengeti lions is all but extinguished.

Enter KopeLion. The project aims to foster human – lion coexistence through community engagement, science and mentorship. One of the most successful outcomes so far is the recruitment of former lion hunters as lion protectors, we heard Roimen’s story last week.

But just how do you ‘engage with the community’ to try and change their minds about living with a dangerous predator. Well KopeLion do this in many ways. Firstly most of the employees are local which means they already have the community’s ear. To the Maasai their live stock are sacred so KopeLion spend a lot of time trying to reduce lion conflicts. They follow the model developed by Lion Guardians Ltd ( http://lionguardians.org )by helping local herders to build sturdy bomas,  searching for missing livestock, treating injured livestock and warning herders when lion are nearby. The lion guardians or Ilchokutis are assigned an area of between 60 and 200km2 where they monitor lions or signs of lions scientifically. They also try to prevent young warriors or Morani from carrying out lion hunts. Part of their role is as mentors to the younger generation.

The Maasai still hold strong traditional beliefs and have strong community ties, recognising and embracing this is one of the reasons for KopeLion’s success so far on its mission to help humans and lions live in peace. The strong local ties mean KopeLion have won trust amongst the local herders and in 2016 they were able to stop more than 20 lion hunts from going ahead and have seen the evidence that their efforts are working in the fact that two of the monitored lion prides now show complete survival.

Ingela and her team at KopeLion are doing such valuable work that I urge you to head over to their incredibly informative website to read more about it.

Meet the People

 

Over the next few months I would like to bring you a few blogs about the many people that work to make Snapshot Serengeti possible. Without them there would be no data for us to pour over but what exactly do they do and who are they?

Dr Michael Anderson is currently in the Serengeti collecting data and checking up on how the various projects that make up Snapshot Serengeti are getting along. As part of the projects commitment to engaging with the local community Michael has begun a National Geographic funded intern program. Its aim is to give young locals valuable training and research experience in the fields of ecology and conservation.

The first student to be taken up on the program is Roimen Lelya Olekisay. He is a Maasai from the Ngorongoro Conservation Area. His story highlights why the intern program is a vital part of both the scientific and conservation work we do. Many local people see wild animals as a threat to their own domestic stock as well as themselves and retaliatory killings are common. Living alongside wildlife is not easy. Without the good will of the local people it is very hard to change their attitudes to the work we do and the animals themselves.

Roimen grew up on the Western slope of the Ngorongoro crater, his family, like many Maasai are herders. As a young boy he roamed all over the Ngorongoro protected area (NPA) with the family livestock. The Maasai are permitted to live in the NPA where they can graze livestock but are not allowed to cultivate the land. Roimen spent two years away at secondary school before returning to the family to continue herding. This is a familiar story for many Maasai. The importance of livestock is paramount and many boys do not complete schooling.

As a young warrior, like many his age, Roimen speared and killed at least three lion. Tradition dictates that young Maasai warriors must kill a lion to become a man. He would have maybe carried on killing lions whenever he perceived a threat to his family’s livestock but he met up with Ingela Jannsen’s group Kope Lion Project in 2013 who work in the area trying to mitigate lion/human conflict. He helped fit a radio collar to a lion and this interaction with the king of beasts up close transformed him from a lion hunter to a lion protector. He became one of Ingela’s lion scouts (more about Ingela and the Kope Lion Project in next week’s blog) recording predator-livestock attacks in the conservation area and working to prevent lion conflicts and hunts. His enormous enthusiasm for lions and their research makes him a perfect candidate to further his scientific skills. This is someone with a natural ease and interest in the wildlife around him and its preservation.

In his new role as the first intern for the National Geographic-Serengeti National park program Roimen will be tracking lions and setting up a camera-trap network that hopes to dissuade human-lion conflicts and generally learning all the scientific skills associated with this work. He has just started and will be with us for six months, hopefully we can catch up with his progress in a few months.

Snapshot Rhinos

This slideshow requires JavaScript.

One of the animals that continue to be a rarity on snapshot Serengeti is the rhino. We have had a handful of capture events over the years.

There are two species of rhino found in Africa; the white or square lipped and the black or hook lipped. The Serengeti is home to the latter. It is a large bulky mammal and as such many a hopeful #Rhino has turned out to be a blurry image of an elephant or buffalo.  Things can get confusing with some of the images but isn’t that half the challenge trying to guess those indescribable blobs? Surely it wouldn’t be the same if everything was easy to id?

Anyway back to Serengeti rhinos.

Just 50 years ago between 500 and 700 Eastern Black Rhino (Diceros bicornis michaeli) roamed the Serengeti-Mara ecosystem but during the seventies the population was decimated by poaching to around 10 or so individuals.

A huge effort is being made by various conservation and government bodies with enormous donations by private individuals to save the population from total extinction. Notably a remnant population in the park was highly protected and slowly, over the next few decades the population made some recovery. In 2010 it was decided that the Serengeti area was being protected well enough to try and bolster the resident rhinos with new genetic stock. It just so happened that a private owner in South Africa had a breeding herd of Eastern black rhino that had been part of the attempt to safe guard the subspecies back in the 60’s, these animals had originated from Kenya. With strict controls by IUCN officials it was deemed these animals were of the right genetic stock to be reintroduced to the Serengeti.

The plan was to translocate 32 rhinos over the next few years and release them in a new site close enough to allow some overlap with the resident 30 or so rhino. Unfortunately the project has been affected by the recent escalation in rhino poaching and it is difficult to find how many rhino have been successfully translocated to date let alone the current Serengeti total population but you can bet it is still small. The IUCN red data list states Tanzania as having 88 Eastern Black Rhino in 2011.

If you are lucky enough to stumble across a rhino capture on Snapshot Serengeti you should definitely celebrate … and don’t forget to # it.

The Challenges of Field Work

Hazard of the job; catching myself on camera-trap

 

If you have clicked through the seemingly endless captures on Snapshot Serengeti then you must have realized just how many cameras are snapping away out there in the Serengeti. Have you ever wondered who looks after those cameras?

Researchers sometimes go to extreme lengths to collect their data and not much deters them from their goal.

On a recent assignment working in Central African Republic I was tasked by our biologist to collect in an array of 40 camera-traps. The park was very large, the size of Wales and very remote, the nearest village was a 12 hours 4×4 drive away. It was also newly proclaimed and had little in the way of infrastructure like roads. Of course, Thierry wanted to survey the areas we didn’t yet know so obviously the cameras were nowhere near any of the smatterings of roads.

He presented me with a mobile phone resplendent with a mapping app which showed the camera trap locations overlaid with our rudimentary road network. I should really say temporal track system as these so called roads consisted of two tire tracks driven through the elephant grass and mud soon to grow over again in the coming wet season. The park consists of a mosaic of wooded savannah and tropical lowland rainforest so you are either struggling through 2 meter high elephant grass or deeply tangled riverine forest growth. Added to the physical challenges of working in the park was the fact of it harboring armed Sudanese cattle herders, poachers and Lord’s Resistance Army militia.

So equipped with the mobile phone, two trackers and 5 armed rangers off we went to collect the cameras. After three hours bumpy ride plagued with biting tsetse fly we got as close to the first camera as any road was going to take us. Using the phone to navigate I pointed us in the general direction praying that the battery would last. If it failed we would be completely lost with no landmarks. Two kilometers later we had narrowed down the camera location to about 20 meters and under the vigilant eye of the rangers myself and the two trackers began searching for the camera in the thick jungle tangle.

Rangers caught on camera-trap whilst on patrol 

 

Once the camera was reclaimed it was bagged up and we set out for the walk to the next camera another kilometer or so away. The whole day was spent battling foliage and insects in the 40o c temperatures for a total of 8 cameras. We made camp for the night; the journey back to base was just too far with so many cameras still to collect. It took 4 days to collect half the array and it was with some relief that we trundled back into base camp having had no encounter with armed men.  A hot shower, something other than sardines to eat and the excitement of examining the camera-trap pictures was a just reward for all our foot work

The cameras were being used to assess what species were present in the park and as such were left up for short periods in small arrays. In the Serengeti however, there are 225 camera traps permanently running in an area of 1125 km2. Just think of the logistics involved with changing batteries, keeping vegetation trimmed back and changing SD cards. Our researchers work tirelessly to keep the project on its toes and over the next few months I will try to bring you their stories about the work we support from the comfort of our homes. We each have our part to play but together we are a team dedicated to furthering a scientific cause.

 

All About Lions

Curbing Idealistic Images and CDV for the Sake of Lion Conservancy

Meredith: Our brilliant team of Snapshot Serengeti undergraduate volunteers at the University of Minnesota are perhaps even more on top of the lion literature than I am! This week, we have a guest post from one such student, Clayton Mazur, describing some recent work of Dr. Packer’s on lion disease spread in Serengeti Park. This post is a synopsis of a scientific paper that can be accessed in full here

S3_L11_R11_ASG0008jkx_1

I propose we play a word-association game. I will offer a word and you think of what comes to mind. “Africa.” Did you imagine Mt. Kilimanjaro, or the towering, lush rain-forests of the Congo? “Wildlife.” Did you envision the sprawling savannas of Tanzania, home to hundreds of thousands of migrating wildebeest? If so, I would bet that your savanna also included the enigma of Africa: the African lion. Was he a graceful figure standing upon Pride Rock looking out over his kingdom? Perhaps he was laying in the shade, his dark mane flowing in the breeze as he waits for the females to return with a kill. I would argue that elegant images such as these are what come to mind for the majority the public. The portrayals of lions in the media- from Lion King to the MGM Lion- support this notion.  As elegant as these images are, reality is less than elegant for the lions living in Serengeti National Park in Tanzania, Africa.

African lions have unique social structures that help them brave the tough conditions of the savanna. Lions live in families called prides; one to two male lions rule a pride. The roles of female and male lions within a single pride are vastly different.  While females hunt, raise the cubs, and reproduce, male lions defend the pride from attack by other predators such as hyenas. Living in a large family group offers lions protection, but it also comes with costs. One cost is that females need to supply a large number of individuals with enough food for survival. Female lions coordinate hunts whereby they stalk prey and then give chase, but this technique only yields about 26% success. The low success rate forces large prides to split or starve.  Perhaps a more interesting difficulty of living in a large pride is the spread of disease within lion populations. As Dr. Craig Packer has found, disease prevalence is a threat to the current lion population.

A fatal disease that persists in the carnivores of Serengeti National Park is Canine Distemper Virus (CDV). CDV infects a range of carnivores, from dolphins to rodents and even some primates. The viral infection causes encephalitis, pneumonia, anorexia and eventually, death. You may be familiar with CDV if you own a dog, for many owners in the US vaccinate their dogs for CDV. In Serengeti National Park, where local villages cannot afford to vaccinate their dogs, CDV is a conservation concern for African Lions who contract CDV from domestic dogs. To try to remedy the concern, an intense vaccination regime started in 2003. Packer and colleagues attempted to characterize the progression of CDV in both domestic dogs and African Lions. Their goal was to determine if domestic dogs were responsible for the infections observed in African Lions. The team also wanted to determine if the 2003 vaccination program had any effect at reducing CDV in the domestic dogs and/or African Lions.

The scientists worked with blood plasma collected from both domestic dogs (obtained from 1992-2012) and from African lions (obtained from 1984-2012).  After collecting the blood samples, the team ran serological tests to detect for the presence of the CDV virus in individual dogs or lions. Using a Bayesian model, the scientists then calculated the probability that an individual lion or dog would contract CDV in one year. The scientists also used sensitivity models to determine the extent at which domestic dogs transmit CDV to lions. From the results of these models, the scientists were able to comment on the fate of the lions with regard to CDV.

The research team drew results by interpretation of the two models. They found that CDV had persisted in the populations of both dogs and lions for more than 25 years. Outbreaks of CDV occurred in 1981, possibly in 1976, and in 1993. Not only do these results suggest a historic presence of the fatal disease in the national park, the dynamics of each outbreak of the disease was unique. The scientists found that the year in which CDV infected the most dogs differed from the year in which CDV infected the most lions. The researchers proposed that this pattern identified domestic dogs as initial vectors for CDV in the park. After a 1994 outbreak in the lion population, the dynamics of the outbreaks become more disjoint. The disjointed dynamics between the domestic dog and lion populations suggest that after 1994, infections cycled through the dog population and the lion population separately. However, the spread of CDV between dogs and lions was not eliminated after 1994.

With domestic dogs established as an initial vector of CDV, the scientists wanted to know transmission rates between domestic dogs and lions. Again, they used a sensitivity model to predict this factor. The scientists found that domestic dogs were ten times more likely to spread CDV to lions than lions were to spread CDV to domestic dogs. With such a high prevalence of CDV in the domestic dog population and the tendency for CDV to spread from dog to lion, the effects of the 2003 vaccination effort were an important factor to analyze for the conservation of the Serengeti National Park lions. The scientists first analyzed the effects of the vaccine on the domestic dog population. Before 2003, there had been very sparse vaccination in villages surrounding Serengeti National Park. As was expected, this vaccination effort did little to curb CDV infection in either lions or domestic dogs. It was not until after 2003 when all villages to the east of Serengeti National Park and all villages within 10 km to the west of Serengeti National Park vaccinated their dogs against CDV did there exist a decrease (~5%) in CDV infections.

With CDV slightly decreased in domestic dogs due to the vaccination effort, was there a similar decrease in CDV infections in the lion populations?  Unfortunately, the sample size of lion serum that the scientists could obtain was not enough to comment on the updated magnitude of dog-lion CDV transmission. Overall, the scientists determined that CDV was still able to cycle in the lion population with very little reduction in the prevalence of the disease. However, not all is hopeless for the lion populations of Serengeti National Park. Dr. Packer’s team suggests that direct vaccination of lions may be more effective at preventing the disease. Additionally, the team suggests that advances in serological techniques would allow for increased accuracy when researching episodic diseases, such as CDV. Implementation of safe vaccines coupled with more accurate serological tests could minimize the effects of CDV outbreaks and ensure the health of the Serengeti lions.

As evident from the work of Dr. Packer and colleagues, there are threats to the conservation of the lion populations of Serengeti National Park. Not only do prides run the risk of individuals starving to death, splitting, and human-lion conflict, disease is another risk factor of living in a pride. Yet, these prides, these perfect families, come to mind when the public thinks about lions. Idealistic images of cubs play fighting or suckling from their mother are important for generating interest and compassion for African lions. One can be content with the image of the brave, courageous, elegant male lion standing on Pride Rock overlooking his kingdom, but one must simultaneously recognize the reality of the lion’s plight. Only then will conservation for lions be truly feasible.

Cheetahs rocking the boat…again!

Cheetahs, it seems, just can’t stop shattering everything we believed to be true about them.

Scientists have long believed that lions (and hyenas to some extent) threaten cheetah conservation efforts —  in large part because they kill so many cheetah cubs. But last year, researchers from South Africa revealed that lions probably don’t kill as many cheetah cubs as folks previously believed. And shortly after that, our research showed that regardless of the amount of lion-inflicted cheetah cub mortality, cheetahs do just fine around large lion populations.

Just last month, another story broke that shakes up how we think about cheetahs. It turns out that not only are cheetahs not as vulnerable to killing by lions, but they cheetahs aren’t nearly as vulnerable to non-lethal bullying either. It was thought that because cheetahs couldn’t fight back against lions – or hyenas – they lost a lot of their hard-earned kills to these ruthless scavengers. (Yes, both lions and hyenas do steal food from each other and from cheetahs.) We knew that wild dogs expend so much energy hunting that they can’t afford to lose even moderate levels of food, and assumed that cheetahs were similarly vulnerable. But, as a recent study from Bostwana and South Africa found out, they aren’t.  It turns out that despite being super fast, cheetahs don’t expend all that much energy chasing down their prey. Researchers estimate that cheetahs could lose a full 50% of their kills to lions and hyenas, and still get all the calories they need!

All in all, it’s beginning to look a lot like the biggest threats to cheetahs aren’t lions and hyenas. Instead, availability of denning sites (as suggested by our research) and human destruction of habitat that forces cheetahs to travel far and wide in search of prey (suggested by this most recent study) are probably much, much greater threats to their survival.

 

Tidbits on wild dogs

One of our long-time Snapshot Serengeti members (thanks Reid!) sent me this NY Times article on African wild dogs. As you know, we don’t have wild dogs in the study area (though keep your eyes peeled! TANAPA did reintroduce them into the western corridor the other year, and I keep hoping we’ll catch one traveling through our grid).

But I am very interested in how dogs interact with the larger carnivore community. And these animals are just *so* cool – incredibly energetic and full of nerve. Watching a small group of dogs defend their kill against a hunting party of hyenas was one of the highlights of my trip to South Africa in June.

The article points out that wild dogs may fare better when lions fare worse (which I’ve reported on here) — and that raises some questions about questions about how to target conservation efforts. Do we have to choose between which species to protect? I’d say “not necessarily.” My dissertation research suggests that although dogs fare worse in small reserves with lions, there are places where wild dogs seem to do just fine. Selous Game Reserve (TZ) and Kruger National Park (SA), for example – big areas that have complex habitat structures. So the answer to protecting the entire carnivore guild may lie in larger, diverse reserves.

There are currently efforts in place to do create a protected area the size of Sweden that spans five southern & east African countries. If successful, according to the NY Times, the Kavango-Zambezi Transfrontier Conservation Area will be the largest terrestrial protected area in the world. Now that’s something to celebrate.
