Of Goats and Cheetahs

It’s weird to think that my favorite memory of my time at Cheetah Conservation Fund in Namibia is the model farm. It’s not like I’ve never been to a farm or that this farm was particularly spectacular. It was really just a big dirt pen, a couple of ranch hands, a dog, and a lot of goats and sheep. But it was a beautiful, clear day and we got to spend it outside, and who doesn’t love farm animals?


I love farm animals but they don't always love me.


Though it might seem odd that a cheetah conservation organization has a farm in the first place, the farm has an incredibly important function. Without a working farm, any recommendations made by CCF staff to Namibian farmers would not come from a place of experience (and would sound downright preachy) and would likely be ignored. How would you react if some foreigner came to your house and told you to change your way of life to protect a pest animal they seem to care too much about?

Fortunately, the CCF team, led by Dr. Laurie Marker, figured that wasn’t going to work. Their model farm is the solution, allowing the organization to show farmers that predator-friendly livestock management techniques work - a farmer that isn’t losing livestock is less likely to kill cheetahs either in retaliation or as a preventative measure.


These had very thick tails that provided extra fat reserves.

Farmers vs cheetahs
At CCF we learned that there’s often a lack of education among farmers regarding proper livestock management and cheetah behavior. This is especially important because 90% of Namibia’s cheetahs live on farmland (Marker, Mills, & MacDonald, 2003). Cheetahs also hunt during the day, so they’re more visible and blamed for livestock deaths more often. If a farmer is losing livestock to predators and all he sees are cheetahs, killing them seems the most obvious way to protect his flock and investment (Nattrass & Conradie, 2018).

With the model farm, CCF can physically show why that’s not a viable long-term solution. Further, they provide in-person farmer training and education on predator-friendly livestock management techniques and cheetah behavior. Cheetahs, it turns out, prefer to eat wild game than livestock (Boast et al., 2016). It’s more likely that livestock were killed by other predators, but farmers don’t see this because it happens at night when livestock are free to roam.


Part of farmer education: Who killed my goat? Fake dead goats demonstrate what predation by different species looks like.

Predator-friendly livestock management techniques
So what does the CCF farm do differently? First, they bring their livestock in at night. Leaving goats and sheep out in the field overnight is an invitation to an easy meal for any predator on the property. Second, pregnant, sick, injured, and young livestock are left in the kraal (fenced area) during the day. Any member of the flock that can’t keep up is a prime target for a predator, so keeping them protected lets them live to see another day. Third, a rancher is with the flock during the day. Having a rancher physically present in the field reduces the number of livestock lost to predators (Nattrass & Conradie, 2018). Fourth, the flock is accompanied by a guard dog - usually an Anatolian shepherd that was raised with the flock. This big dog is a big deterrent for predators (I’ve heard that booming bark and it is to be feared), especially for smaller livestock like goats (van Eeden et al., 2017).

But why would farmers want cheetahs on their properties anyway? It goes back to cheetahs having a preference for wild game. A healthy cheetah population means wild game numbers are kept in check, ensuring enough grazing for everyone. Overgrazing leads to a lack of food for both livestock and wild game: if there isn’t enough wild prey the predators may turn to livestock. Overgrazing also allows an aggressive thorny bush to take over - reducing the amount of usable space on the farm. Plus, many farmers are turning towards eco-tourism activities to make extra money, and wild cheetahs are a huge draw.

All of these activities directly increase the amount of money a farmer can make from his property, ensuring survival of cheetahs. If farmers aren’t killing cheetahs on their properties, cheetah populations can grow and the ecosystem can maintain its balance. A major theme of my time at CCF (succinctly stated by CCF Farms Manager Johan Britz) was “if it pays it stays” and that holds true for any animal on Namibian farmland.
