The fires could spread in any direction and we don’t want to lose further lives."Hanekom emphasised the necessity of respecting the potential impact of fires on the wildland urban and commercial agriculture interface, as a serious build-up of invasive alien plant invasions increases the risk of fire damage. "Very interestingly, from above it is clear that indigenous forests have not been at risk as alien invasive have been," he said."As climate change takes hold with longer, hotter periods, the risk just intensifies. We need to reduce that risk."
