In Newlands Forest on the slopes of Devil’s Peak you may notice trees with unobtrusive grey bark part of the way up. Enquiries led to a man who paints them.

Willem Boshoff is sitting under a turkey berry tree. He’s a tall man with a slightly greying beard, easy warmth and an infectious laugh. He loves this forest. As we talk, there’s the smell of brewing tea, which makes sense given all the tannin rotting on the forest floor. 

Behind him is a massive wild almond, its multiple trunks flung wide like a giant octopus. The ground is a yellow carpet of fallen leaves and the living leaves above are filled with the chuck and chatter of birds living their perfect lives.

Earlier, as we walked uphill through Newlands Forest on the slopes of Devil’s Peak in Cape Town, however, bark stripping had exposed ugly scabs and raw wood. Some trees were entirely ring-barked, others dead and fallen. 

“There’s so much environmental damage in the world,” Boshoff says. “It feels good to be able to be here helping this forest to survive.” When he walked into the forest in 2019 that seemed unlikely, he explained in an interview.

Willem Boshoff: In the ravine up near the Contour Path, beautiful, lush, big, old trees had been growing for centuries and it looked like a herd of elephants had gone through. Dead and fallen trees all over the show. Rips in the canopy. 

I didn’t know what was going on. I thought SANParks was killing bad trees. Then I met a ranger and he said it was illegal bark stripping.

Newlands was evidently under so much strain from stripping that some areas of the forest had crossed a tipping point. It really affected me. My poor wife had to deal with me walking around in the forest at 10 o’clock at night with my little head torch and pepper spray to catch these guys.

Don Pinnock: And did you?

WB: Never, never. The guys are extremely brazen but they know the terrain. Once you’re in the forest, it’s very hard for anybody to see you. Bark is literally low-hanging fruit, very easy to strip and get away with it. During Covid, there was an absolute explosion of stripping.

I started googling and found some articles about the phenomenon. I was like: Wow this is really bad. I’m seeing mature trees being bark-stripped, protected species like assegai … Cape beech, Cape hollies. I started posting on social media about it, saying this seems to be a big problem and is anybody doing anything about it?

A guy called Neil Williamson contacted me and said he’s seeing the same thing. Next thing we had a website up and the Newlands Forest Conservation group was born. Some people were asking, what can we do? Some were suggesting drones or tripwires.

We heard that some arborists had success preventing bark stripping in urban areas by painting trees. So we painted some Cape beech trees in the area guys were actively stripping to see what would happen. We used weak, grey PVA, it’s not too intrusive. Then we observed the site for a few months. People were stripping all around it but not the painted trees. We’d found a solution.

DP: There are a lot of trees in Newlands Forest…

WB: Yeah, well we had a problem of scale, of course. It took me a whole afternoon to paint eight trees. I had been doing hacking — that’s eradicating invasive alien plants — in my spare time and explained my problem to Sandy van Hoogstraten of the Sugarbird Trust, an alien plant removal PBO, and she asked: “How much money do you need to paint the forest?” Suddenly we had the budget to put a permanent team together.

We experimented with different techniques — spray on, paint on, how to reduce splatter, different levels of dilution — and over time we found the best methodology.

DP: So, how many trees have you painted?

WB: Over six months we painted about 3,000 but lost count because the team was working so quickly. We started with mature specimens. I mean, if you shoot a mature rhino, in six years you’ve got a mature rhino again. If you ring-bark a 150-year-old assegai tree, there’s a 150-year hole in that forest. The loss of those old trees was so grievous to me and we’d lost hundreds of them.

Since we’ve painted the remaining ones, none of them have been stripped. Old trees form the bulk of the forest canopy and they seed and regenerate the forest. Then we looked at the smaller trees and decided to preserve 10-, 20-, 30-year olds as well.

DP: Which trees are being targeted by strippers?

WB: Cape beech, Cape holly, assegai, stinkwood and sometimes wild peach, red alders, hard pear and a few others. There are very few stinkwoods left.

Sensitive terrain


DP: Is there any medicinal value in the bark?

WB: There is some value, but the efficacy is considerably lower than common medicines you can buy in a pharmacy. There are two dynamics involved. One is access to traditional medicine that may be cheaper, the other is traditional beliefs. 

Becoming critical of a cultural practice is very sensitive terrain. We’re not critical of a practice that has been going on for centuries, we are critical about it being done in a completely unsustainable manner, and then going from unsustainable to extremely destructive. For some, it’s simply a commercial criminal enterprise.

DP: Why does the paint work so effectively?

WB: The [bark] strippers aren’t sure what’s in the paint. Could it kill you or make you sick? They don’t necessarily know. And the guys who buy it from them and their customers are not going to trust painted bark.

The project has been an enormous success. Not a single tree we’ve painted has been stripped. We went from bark stripping being the number one threat to Newlands Forest to it currently hardly being a threat at all. 

DP: What is Table Mountain National Park doing about it?

WB: SANParks do what they can, but the park is very difficult to police. You’ve got a metropole with 4.5 million people around this little indigenous forest. There’s no fence. In it is a product that a large part of that population wants. And when Parks find the guys and they get charged, they often don’t get prosecuted because it’s considered such a low-level crime. Where does it sit in relation to murder and rape?

I’d like to see the money generated by Table Mountain National Park employed more efficiently. Some park rangers really go the extra mile and I’d like to see them well funded. At the same time, the park is enjoyed by thousands of citizens every week. There’s almost an entitlement that goes with that. 

I don’t want to step on people’s toes, but I think public interest organisations need to step up and the public need to recognise that we have a responsibility. As users, we need to contribute to the park’s upkeep.

Of course, there are those who do. The Sugarbird Trust has little signs on the mountain with a Snapscan code and somebody contributed R50,000 the other day. And look at the amazing work that Friends of Table Mountain or Take Back Our Mountains does. Friends spent half a million rand last year repairing trails and this year we hope to do double or triple that amount — all public funding.

DP: Do you have a favourite tree?

WB: I have a soft spot for assegai, but also stinkwoods. Actually, I love the red alder as well, they’re beautiful. But, you know, the ecosystem as a whole is a beautiful thing. It’s not just about individual trees.

Boshoff is an actuary who spends more time on Excel spreadsheets than among trees. He has meetings up ahead and needs to go. He leads the way down along the deeply-incised Newlands River, sidestepping hurtling, happy dogs and their owners. He pats a large tree beside the path.

“Wild almond,” he says, “a descendent of Jan van Riebeek’s original hedge, maybe.”

It’s hard work caring for a forest, I say, just before we part ways. Why do you do it?

“I guess I care. I want future generations to be able to enjoy this place. I would love my daughters to be able to walk into Newlands Forest one day, look up at a 200-year-old indigenous tree and marvel at its beauty. I think it’s worth protecting.” DM
