The Junior Forest Wardens (JFW) is a Canadian volunteer-led organization focussed on developing a wildlife and wildlands conservation ethic in youth.  The organization is almost a hundred years old.  It began in the 1920s, when a group of boys reported a forest fire to a local forest ranger in the province of British Columbia.  The magazine “Forest and Outdoors”, which was published by the Canadian Forestry Association (CFA), devoted a section to the activities, interests, and education of children.  When a story was published in 1929 about how two boys discovered a small forest fire on Snug Cove on Bowen Island in British Columbia and assisted a Ranger in putting it out, an interest in this type of assistance grew.  In the publicity that followed this incident, boys across the province wrote to find out what they could do to help in similar ways.  As a result of this, Charles Wilkinson, a member of the Canadian Forestry Association in the region, formed the Junior Fire Warden program as a vehicle for teaching boys about forest protection.
