The Idaho Department of Lands hopes its recent crackdown on suspects of human-caused fires will spark residents to take notice and caution and ultimately reduce the blazes. Nearly 80 percent of wildland fires last year on state, private and federal lands protected by IDL — 224 of the 282 incidents — were human-caused. That trend has caused IDL to have a renewed focus on finding the culprits, holding them accountable and recovering taxpayer funds used to fight the fires, said Sharla Arledge, IDL spokeswoman.
