Wildfires are up by 50% from 2012 to 2018 in the California area where Orange, Riverside, San Bernardino and Los Angeles counties come together, when compared to the previous 97 years, according to a study by Hills for Everyone.

The technical consultant for the nonprofit, Melanie Schlotterbeck, told ABC 7 the study, 104 Years of Wildfire History Near Chino Hills State Park, showed the land staff at the organization worked to protect was slowly burning away.

“Of the 151 wildfires that we have documentation for, only two of them were caused by lightning strikes,” Schlotterbeck said.

The rest were human-caused, according to the data the organization said it collected from fire agencies and newspaper records.

Schlotterbeck, said it first published wildfire statistics for the area for 1914 through 2011, “but what we realized was with the 2017 and 2018 fires that happened across the state of California, we really should be understanding what has happened here again locally.”
