Fire, Succulents and South Africa

Like the American West, Australia and elsewhere, Africa is having an increase in devastating wildfires. Numerous succulents are native to the continent, and in the south the climate is similar to that of coastal and southern California.

Recently I heard from Talfryn Harris, a fire manager in Johannesburg who was working on a presentation for their succulent society on the role of the plants in fire protection. “Last year we had very destructive fires on our south coast where many homes were lost,” he wrote. He asked permission to show my YouTube video, Do Succulents Catch Fire?
Of course I said yes, but added, “I don’t want to give the impression that succulents can serve as a wildfire barrier that guarantees a home won’t burn. Plants that store water in their leaves and are slow to catch fire serve merely as a way to lessen the threat. Succulents really do need to surround a house, as shown in my other wildfire video: Succulents as Firebreak. There are so many factors that come into play, wind especially. I compare myself to a meerkat, the way I watch the wind during fire season here in Southern CA.”
Later Mr. Harris sent me his PowerPoint presentation (below). It describes the impact that global climate change has on wildfire, gives practical tips for protecting homes, and explains why succulents are a good landscaping choice for at-risk areas.
He also suggested that “a useful fire-wise succulent that I would add for South Africa is Carpobrotus edulis (aka Mesembryanthemum edule) which is great as a fire-wise and medicinal succulent lawn.  However I believe it is invasive in Australia and California. The African people in the townships around Jo’burg call it ‘chips’ because of the resemblance to what you call french fries. One medicinal use is to infuse a flower in a jar of honey and then after 4 months use that for colds and sore throats. It is also a very useful remedy for the oral thrush that accompanies HIV/AIDS.”
I felt I had to inform him that when I was researching my article for the Los Angeles Times about how succulents helped protect the Schaefer house back in ’07, a fire fighter told me that dry plant material beneath carprobrotus leaves can smolder for days, causing flare-ups and endangering anyone who walks through it.
Have you wondered why wildfires are burning hotter than ever and causing unprecedented devastation? In his book, “Land on Fire: The New Reality of Wildfire in the West” (Timber Press), acclaimed nature writer Gary Ferguson explains why fire suppression and chronic drought have created a dire situation, and the ways nature responds in the aftermath of wildfire.
