Grassfires have lit up our city and black plumes of smoke have ascended over it too, but whether controlled or wild, these fires spark the debate of whether they are beneficial or not.
Imagine driving down the N1 highway when a white haze takes over the sky and obscures your line of vision. The car, truck or whatever in front of you an unrecognisable haze no matter how hard you squint. Hazards blink at double speed, a desperate safety warning that you are on the road too.
You can smell the scent of burnt grass, smoke filtering through your air vents. You try to close them, but it is too late, the car has already filled with dust and ash. A cough escapes as you wipe your watery eyes and then you see the flames engulfing the nature reserve you drive by every day. Bunnies hope, birds fly, and snakes slither away from the flames. You watch as the firemen throw water on the flames, get in their truck, and drive away.
Johannesburg’s Winter months have seen many grass fires blazing alongside highways and homes, but no one really understands if these fires are readying the ground for new life in Spring, or if they are random and just killing many species in their wake.
Sporadic fires and controlled fires look identical, with the only difference being the havoc they wreak.

Controlled burning of grasslands or velds are actually a common occurrence in Johannesburg and other parts of South Africa. Joburg City Parks says this acts as a firebreak so that if accidental fires do occur, they do not spread very far. However, they also act as an ecological resetter — fire removes dead matter from the ecosystem which could potentially house harmful insects, pests, weeds, or diseases.
Research says dead matter also holds onto nutrients that would otherwise be absorbed into the soil for other plants to use as food. The ash produced from grass fires can also act as a natural fertiliser for plant growth in the Spring as it contains vitamins and minerals like phosphorous, calcium, and potassium.
Examples of these sorts of fires can be seen in the black grass dressing Johannesburg’s velds. Many of us do not even realise a grass fire occurred because it was quick and controlled, but impactful.
Accidental fires, or uncontrolled fires, are not ecologically friendly as they just burn and burn until they are stopped — hopefully. They occur mostly near very dry grasslands, usually due to a lit cigarette being discarded or just bad luck. They sweep close to residential areas, cars, people, and anything else in its path.
Let us not forget the little creatures that never make it out alive like earthworms, spiders, ants, and other insects vital for aerating soil or biologically controlling pests. Bird nests also die in the blaze, including their chicks or eggs that were nestled inside.
An example of this would be the huge black cloud of smoke that covered Brickfield Road in Germiston on Saturday, August 10. What was meant to be a controlled burning of a large veld turned nasty when the wind swept the flames to a neighbouring plastic recycling plant. The smoke let off from these types of fires also contribute to air pollution as it contains harmful greenhouse gases. Bethany Augliere, a writer for Earth Magazine, says burning grass releases nitrogen pollution that harms air quality.
Another instance was on Sunday, August 11, when veld next to a busy main road between Bedfordview and Germiston was under a controlled burn but soon got carried away and closer towards boundary walls of residential homes. Because of the close proximity, this thick and polluted air was inhaled by humans and their pets which can have disastrous health implications. Firemen were told to keep the area on their radar to ensure the flames fizzled themselves out relatively soon, which they did.
Fire is a scary element, one that can burn anything in its path to the ground. As children, we were always told not to play with fire, lest our fingers get burnt. But then we watched phoenixes combust into a blaze on television screens, and saw a new creature emerge from the fire’s centre. So, is fire really just a killer or also a mother giving birth to new life?
