This indicator measures the area burned each year by wildfires, based on records of fires since 1919 from the Wildfire Management Branch of the BC Ministry of Forests, Lands and Natural Resource Operations. The area burned from year to year is highly variable and is closely correlated with both temperature and precipitation (Utzig, Boulanger & Holt, 2011). Therefore, data have been analysed using a ten year moving average which measures the average area burned over the previous ten years.
