In BC, almost 40% of the wildfires that started between 2015 and 2024 were sparked by people — our campfires, our infrastructure, our vehicles. To avoid preventable fires, officials ban campfires, restrict the use of heavy machinery and sometimes prohibit the use of off-road vehicles. But before making those decisions, they need to determine just how bad the fire danger is in the first place. …The billboards, with their green, yellow, orange and red markers that denote different fire danger levels. …Forest fire danger rating research began in Canada in the 1920s with studies in experimental plots to investigate the moisture content and flammability of forest fuels — everything from the fine needles and twigs that litter the forest floor to the deeper organic layers below. Over time, researchers incorporated that work into a series of scientific models now used across Canada and around the world to estimate wildfire danger and fire behaviour.
