Up to 40 fires raged in the Table Mountain National Park (TMNP) from Sunday 18 April to Monday 19 April, investigation findings revealed at a media briefing on Thursday.
Fire investigator Rob Erasmus explained in detail that responses to quell the fire were conducted quickly, but due to humidity levels being below 20%, combined with an unseasonably warm day, any type of vegetation in the path of the fire acted as kindling to allow it to spread faster than firefighters could keep up.

To make matters more challenging, a change in wind speed and direction took place roughly 30 minutes after the first fire was reported to authorities.
“Each ember started a new fire. We’re talking 20 to 40 fires starting. Some amalgamated, others changed to make their own fire paths,” he said.
After progressing in a south-easterly direction, the fire moved with “rapid speed” towards Rhodes Memorial. He said within the space of 10 minutes, patrons at the Rhodes Memorial Tea Garden went from enjoying a late breakfast to being evacuated.

The fire then made its way across the N3 and continued to spread until around 11pm, when the wind direction changed again, pushing the blaze up Devil’s Peak and in the direction of the University of Cape Town, before burning back towards the city at the front of Devil’s Peak.

On Sunday night around 8.30pm, reports of another fire were received in the Vredehoek area. Authorities found three separate fires burning in the area, but it was found the distance between the morning and evening fires was too great for the two to have been connected.
On the Monday morning, fires raged in Vredehoek and were only contained by mid-afternoon.

Natural causes of the fires were ruled out due to there being no lightning in the area, no rockfalls and no spontaneously combusting vegetation.
A ditch was found close to where the morning fires started, but no evidence of human occupation was found. CCTV footage confirmed that from 6am no signs of human activity were found on the urban edge of the TMNP.
This also ruled out the fires being started accidentally or due to negligence.

Erasmus assured that firebreaks were in place and were regularly maintained.
“We have proof they were replaced and maintained,” he said.
Pine trees make fine kindling for fires, but Erasmus said these trees, although slowly being eradicated in some areas, would not be completely removed.
This is because the trees form “part of the park’s heritage”, as per UCT’s Heritage Park Framework.
However, ongoing efforts are in place to remove a number of exotic species such as bluegum and pine trees.

Fuel loads, which come in the form of alien invasive species or fynbos, are regarded by some as a dangerous catalyst that could increase the frequency of fires at TMNP.
However, alternative methods are being looked into, with some vegetation dangerously close to homes and the park’s urban edge.

Erasmus said the mill burnt down very quickly due to embers landing on the roof of the structure. The loss, although regrettable, was not able to be avoided.

UCT’s campus has thrived as a mini forest for many years without incident and, until the most recent fires, this was never a problem.
However, because of low humidity rates, any ember flung into the air was likely to cause a fire.
Erasmus explained that when the fire spread to UCT, thick smoke was observed. Within this smoke “hundreds if not thousands” of embers were floating around, sparking new fires across the campus at the same time.
“A lot of the fires were not observed initially because of smoke.”
