Between 2009 and 2018, the number of acres burned and the number of wildfires has been trending up, according to data provided by Cal Fire.

Scott McLean, a spokesman for Cal Fire, attributed the trend to at least three factors — drought conditions, weather and an increase in population.

“It’s just an accumulation of a whole bunch of pieces and parts,” he said.
