Tracking Cats, Cows, & Coexistence

When you think about lions in the wild, what comes to mind? Perhaps images of great prides roaring across a pristine savanna teeming with wild prey like zebra, wildebeest, and giraffe. While some lions might live this lux lifestyle, most share space with human and domestic animal neighbours. Coexistence among people, livestock, and lions has existed for millennia, but as with all neighbours, conflicts do arise. Lions may prey upon livestock for food or people may kill lions to protect their livestock. These interactions have serious implications for lion conservation, human livelihoods, and environmental well-being.

Understanding interactions among lions, livestock, and people in shared landscapes is critically important, but also very challenging! Within each of these three groups exists a huge diversity of identities, preferences, and experiences that can affect how they all interact. Do some lion individuals prefer hunting cattle instead of buffalo? Do women and men differ in their attitudes toward or experiences with lions? Not all people or animals are the same, of course!

To explore human-lion interactions at a deeper level, we needed detailed information about the day-to-day lives of as many individuals as possible. Lions and livestock aren’t very interested in having a chat over tea though, so in Laikipia, Kenya, we’re using another technique to learn about their lives: biologging.

If you’ve ever worn a smartwatch, you’re already familiar with the concept of biologging – using small, body-borne devices to record data about an individual’s movements, physiology, and surroundings. You can track the miles covered and calories burned during your morning run using your watch or phone; we can do something similar with lions and livestock using other devices.

For lions, we use SMART collars – Species Movement, Acceleration, and Radio Tracking, that is. These collars collect GPS location and other data at regular intervals, showing where lions go and what they’re doing. In northern Laikipia, an incredible vet team from Kenya Wildlife Service has helped put collars on 11 new lions this year, bringing the total here to four males and 11 females collared. Data from these collars are not only shedding light on how different lions live in this complex landscape, but also helping pastoralists keep their livestock safe from lion predation. Another cool thing about SMART collars: when it’s time for them to come off, we can remove them via remote control without having to bother the lion at all!

Instead of collars, cattle get ear tags. Putting ID tags on the stiff ears of cattle is common practice in ranching, but these smart tags go a step further. Each ear tag has a tiny solar panel that powers the transmission of GPS points and activity data every few hours, allowing us to remotely track a cow’s movement. The information gathered by these GPS ear tags is invaluable for conservation research, human-carnivore conflict mitigation, and livestock management alike. Earlier this year, we collaborated with six pastoralist communities and three conservancy ranches to deploy 100 ear tags. Some tags have even helped owners find lost herds!

The longer these lion collars and livestock tags are out in the field – and the more we can deploy – the more overlap we get in lion and livestock data. This will enable us to explore how individual lions and cattle herds interact, as well as why some interactions lead to conflict.

What about people?

Cattle aren’t just roaming across Laikipia by themselves; people are there, too. How one person lives in and uses their landscape isn’t necessarily the same as another person, though. People with different identities and social roles – like gender, socioeconomic status, or occupation – may use their environments in especially distinct ways. For example, a woman who runs a convenience store in town goes to very different places during a day than a man who herds his family’s cattle does. These differences, in turn, can lead to different levels and types of interactions with wildlife like lions. Unfortunately, the experiences and needs of underserved groups such as women or people of colour have often been overlooked in conservation – we’re trying to change that.

Over the past two years, we have collaborated with community leaders and social scientists in developing a plan to better understand how people with diverse identities interact with lions in northern Laikipia. The plan has two main parts: 1) phone location tracking, and 2) social surveys.

For those who would like to participate, we will turn on location tracking on smartphones to understand how different groups of people use the landscapes they share with lions. Our survey team will also interview community members one-on-one to learn about their attitudes, experiences, and behaviours regarding both lions and conservation. We appreciate everyone who has decided to participate in this work so far and make sure to keep their data secure! We’re excited to see how this research might help expand whose voices are heard in conservation.

Scaling up

Individual biologging is great for looking at fine-scale interactions in real time – but what about the big, long-term picture? Better predicting and preventing conflicts before they happen could give human-lion coexistence a major boost. We hope to do just that by combining data from lions, livestock, and people with landscape mapping.

These aren’t your standard road trip maps. The Davies Lab at Harvard University surveys landscapes using state-of-the-art sensors flown on drones, producing extremely detailed maps that show colour, temperature, and 3D structure. Imagine something like Google Maps Street View but for natural ecosystems. These drone-based surveys provide information on everything from vegetation to microclimates to roads. By mapping the areas in Laikipia that collared lions, tagged cattle, and human participants use, we’ll try to pinpoint conflict hotspots and direct help to where it’s needed most.
