Why Worse Wildfires? Part 2
Figure 1 Managing forest ground fuels
Why worse wildfires? The short answer is more humans cause more wildfire ignitions in altered landscapes. Since 1970, California’s population doubled, adding 20 million people. As more human habitat was developed, the increasingly disturbed landscape quickly became covered in easily ignitable invasive grasses (see part 1). To protect human habitat, fires were suppressed and ground fuels increased. Development also expanded a vulnerable electric grid. Furthermore, more people increased the probability of careless fires and more innocent accidents. And sadly, a larger population added more arsonists.
