Investigators examining the cause of the Killarney wildfires, which devastated thousands of acres in the national park earlier this year, believe the fires were started accidentally.

More than €21,000 was spent by the National Parks and Wildfire Service (NPWS) on private aerial support to contain the three-day fire, which devastated the southwestern section of the park in April.
