Primate Conservation in the Pearl of Africa

A group of baboons at Kibale National Park make behavioral observation easy.

My sophomore year of undergrad at Cornell, I applied on a whim to Hunter College’s winter break study abroad program with Dr. Jessica Rothman, a primatologist in the Anthropology Department at Hunter. I have been passionate about wildlife since childhood.  Even as a toddler, I would stare unblinkingly at my safari motion lamp, watching the elephants, giraffes, and lions strut in an endless loop and dreaming of the day that I would see them for myself. When I was admitted into the program, my dream was coming true.

It’s no secret that there is a danger in setting high expectations. In the weeks leading up to my 2018 trip to Uganda, I had ample time to question whether my study abroad experience could possibly live up to my hopes. And I can’t count the number of times I screamed at the television in horror in the week before my trip, as the Weather Channel heralded the arrival of Winter Storm Grayson, the bomb cyclone that slammed the East Coast two days before my departure from JFK Airport. Pre-trip jitters aside, I can say with tremendous gratitude that this trip managed to exceed my already sky high expectations. This experience lent me an educated view of the nuanced complexities of conservation. 

 The course, Tropical Forest Conservation, was primarily geared towards field research, so we spent time learning how to identify flora and fauna in the forest, how to track primates as they moved throughout the forest, and how to best observe them in Kibale National Park. This first leg of the trip allowed me to see a range of species in their natural habitats and to see for myself the ecological diversity present in the park that makes its protection essential. I also gained a better understanding of the unique opportunities and challenges associated with field work. 

The second leg of the trip in Queen Elizabeth Park consisted of game drives, during which we saw lions, elephants, warthogs, hippos, African buffalo, and more. Seeing these species for myself was definitely among my favorite parts of the trip. However, throughout the course, we also heard lectures from various conservation workers in Uganda, from researchers to members of the Uganda Wildlife Authority. I had the chance to hear firsthand about some of the challenges of conservation and to understand the complexities of achieving lasting change. Before this course, I saw the challenges to conservation as being quite simple. I imagined those who would seek to harm animals as movie-style villains, all but swathed in black capes. The narrative is certainly riddled with villainy, but I now know just how many complicating factors there are. Many people in Uganda have complex relationships with their native wildlife because the animals are inadvertently hindering their way of life. A single elephant can consume in one night the crops that would feed a family for a year. Wild animals can at times pose a threat to the livelihoods of local people, so asking them to help conserve their wildlife is more complicated than I had initially thought.

I was so intrigued by the challenges to conservation that months after my trip, I interviewed Dr. Colin Chapman, a professor in the Anthropology Department at McGill University, Canada Research Chair in Primate Ecology and Conservation, and the head of the Kibale Monkey Project in Uganda about his conservation and humanitarian work. Dr. Chapman’s extensive research work around the globe has lent him a unique perspective on how to best promote an interest in conservation. He told me that “Almost everywhere the local people want to conserve. There’s a real pride in their forests and their animals. When they don’t conserve, it’s mostly because they feel they don’t have a choice. If you have to cut down a tree to send your children to school, what’s your choice? I think that’s the thing that I’ve found around the world and I find it really positive. If we can provide things that make life a little bit easier, it’s basically going to mean that there’s a big will to conserve.” My own experience in Uganda led me to similar conclusions. Dr. Chapman’s efforts to improve park-people interactions have already yielded positive results. (For more information, I recommend visiting Dr. Chapman’s website: http://www.chapmancolin.com/ ). 

The issues surrounding conservation are so multi-faceted, they will require an equally complex approach to solving them. My trip to Uganda and the conversations that ensued were a tremendous learning experience for me. Through my different conservation and wildlife medicine related experiences, I have met so many different people with different backgrounds, opinions, and skill sets. What unifies them is a passion for conservation and a drive to support animal populations and their environment, and, in doing so, better the human experience.

The Realities of Infectious Disease Research in the Field

Thanks to funding from Expanding Horizons, this summer I partnered with Conservation Through Public Health (CTPH) to conduct research in Queen Elizabeth National Park (QENP). CTPH is a non-profit non-governmental organization, focused on improving the health of animals and people around protected areas in Africa while also advancing initiatives in wildlife conservation. Put more simply, it addresses the reality that wildlife conservation cannot occur without simultaneous partnership with humans whose livelihoods are closely intertwined with, and often dependent on, the same resources that endangered wild animals need. In my opinion, one of the most interesting problems in wildlife conservation is how to make conservation a priority for everyone. Dr. Gladys Kalema Zikusoka, one of the founders of CTPH and the first wildlife veterinarian for the Uganda Wildlife Authority (UWA), was motivated to address this need. Since it was founded in 2002, CTPH has implemented public health programs in Bwindi Impenetrable National Park, QENP, Mount Elgon, and other protected areas in Uganda. CTPH has worked in communities with significant interaction with wildlife, training Conservation Community Animal Health Workers to assist researchers in sampling animals and to report signs of disease outbreaks to UWA.

My objective for this summer was to conduct research on the prevalence of brucellosis and tuberculosis, both zoonotic diseases with the potential to infect humans, in African buffalo and cattle in communities around QENP. Three different villages around QENP were chosen based on disease prevalence of free range cattle and proximity to the national park. In a study published by Dr. Gladys and other researchers in 2005, the prevalence of Mycoplasma bovis and Brucella abortus was 22% and 2%, respectively. The first survey of bovine tuberculosis in QENP in 1960, which was referenced in Dr. Gladys’ study, concluded that the disease had originated in cattle and spread to buffalo. Infected buffalo were only found in areas of the park close to villages with cattle that were positive for tuberculosis. Since this wildlife reservoir has been established, the challenge now is to eradicate the disease in both populations. My research consisted of conducting surveys of pastoralists, and sampling blood from cattle to perform laboratory tests for the infectious diseases. Having worked in research laboratories throughout my undergraduate career, it was easy for me to learn the procedure for the brucellosis serum agglutination test. However, it was much more fulfilling to conduct surveys because I learned so much about common practices in raising cattle outside the United States, perceptions of foreign researchers, and how it is extremely challenging to control all the variables when conducting research in the field.

To conduct surveys, I woke up at 5:30 am to drive to villages before the cattle were led, by herdsmen, into QENP to graze for the day. It was necessary for the cattle to leave so early in order to begin feeding before the heat of the day reached its peak. Our team once drove over five miles into QENP to chase after a specific group of cattle to sample. That journey was a testament to how much energy the cattle had to expend to find food, relative to the poor nutrition they received from the dry, brittle, and overgrazed grass.

In a moment that made the fatigue from chasing cattle worthwhile, I spotted a buffalo and a few Ugandan Kob mingling with the cattle. Just as there are no boundaries between wildlife and livestock, there are no boundaries between livestock and humans in the village. If a buffalo infected with Brucella abortus were to have an abortion in QENP, and a grazing cow ingested the placenta or vaginal discharges, the infection could be passed to the domestic cattle. A human that drank raw milk from an infected cattle could then become infected, as well. The challenge of developing boundaries of QENP around and within pre-existing communities without allocating grazing land is there there are insufficient natural resources. Cattle cannot rely solely on grazing within the village. While the government punishes people for grazing cattle in QENP, it does not provide alternative methods to feed cattle that are affordable. Nutrition is essential because cattle or buffalo that do not receive enough nutrition from grazing have a less robust immune system to respond to and eliminate infection.

Before beginning my research, I traveled to each village and met each village leader. The village leader is an elected individual who holds the most political influence within the village. Dr. Kellen, a Ugandan wildlife veterinarian, translated information about CTPH, the research project, and what we would need. After receiving support from all three village leaders, we traveled from house to house with a local to facilitate introductions.

Despite the support of the village leaders, I immediately ran into opposition from community members. At the first house, before we had finished communicating the premise of our research, a villager interjected to say that many researchers in the past had come, collected samples from his cattle and asked him questions, but none had distributed any results or provided compensation. This theme was repeated throughout houses in all three villages. There were also accounts of researchers injecting vaccines around the tail-head of cattle and causing necrosis of the entire tail. Anyone who assumed that we were researchers from Ugandan Wildlife Authority refused to talk to us or allow us to sample their cattle. It was concerning to see that the governmental body responsible for protecting wildlife did not seem to have the support of the people. UWA charges entrance fees for almost all the protected areas in Uganda, for many safari and animal tracking opportunities, and for permits to conduct research on animals in Uganda. However, only a small percentage of this income is given to the communities around the national parks, provided that the people have demonstrated certain initiatives toward advancing wildlife conservation.

Once we explained that we were with Conservation Through Public Health, an independently-run, Ugandan-based organization with a history of disseminating results back to communities, the locals became much more receptive to participating in our research. I surveyed 51 pastoralists and sampled 97 cattle. Through the surveys,  I was able to analyze the risk factors, such as handling of newborn calves, slaughtering of cattle, and type of milk consumed, that could lead people to brucellosis infection. I learned that the local name for brucellosis was omusuja gwente, which translates to malaria of cows. Wildlife conservation will only succeed with teamwork from multiple different sectors, and without the pastoralists reporting infectious disease outbreaks to veterinarians and UWA, a significant player in disease detection would be lost.

As a result of the surveys, I identified certain practices that places people at risk for brucellosis transmitted from cattle, including close contact with newborn calves, and leaving aborted calves in the fields or feeding them to other animals. Thirty-nine percent of respondents had observed at least 3 clinical signs of brucellosis in their cattle (abortion, stillbirth, weak calf, retained placenta, orchitis/epididymitis). From the serum agglutination test for brucellosis, I determined that there was 0% prevalence of B. abortus in the cattle that were sampled. While this is positive preliminary data, more in depth investigation should and will be conducted to whether this is the true prevalence.

As a pre-veterinary student, a professor encouraged me to pursue both wildlife and livestock interests because of the need for veterinarians in developing nations. It was a concept that was very new to me then, but resonates with me now. My initial plans for darting and sampling buffalo for my project were canceled due to numerous bureaucratic issues, but I learned that wildlife veterinary medicine isn’t usually chasing outbreaks or performing surgeries. I have a lot more to learn and explore, but I am very glad to have journeyed to Uganda to get a glimpse of what is possible in the years to come.
