UNIVERSITY PARK, Pa. — Francis Alvaré, a Penn State forest ecosystem management major with a minor in military studies, assisted the National Guard's forestry department in a series of prescribed fires on training facilities as part of an independent study program in the spring of 2017.
Alvaré, a senior from Havertown, Pennsylvania, discovered the program by asking faculty in the Department of Ecosystem Science and Management about opportunities to fulfill the independent study requirement for his major. Like many forestry enthusiasts, he enjoys spending time outdoors, and also had developed an interest in firefighting.
"I joke that I wanted to be a forestry major because it's like being a professional Boy Scout," he said. "My dad was a College of Agricultural Sciences student, and I had friends I could ask about the curriculum, which helped me decide what to major in."
Associate Professor of Forest Ecology Margot Kaye, who teaches Forest Fire Management and Ecology, and Brent Harding, a senior forester within the college, connected Alvaré with forest program managers at the Department of Military and Veterans Affairs Bureau of Environmental Management, Forest Management Section at Indiantown Gap. The organization is made up of a group of civilians who help the National Guard maintain its ranges and training lands, including ranges for tanks, artillery, long-range weaponry and aircraft weaponry.
By periodically conducting prescribed fires within "burn units," specific areas with distinct characteristics that burn in a certain way, the National Guard is able to prevent the start and spread of more serious fires on and around its training facilities.
"Our objective is to safely burn the areas they train on to keep the understory or grasses to a manageable level, so they don't interfere with sight lines, and to keep the fuel bed (the amount of flammable material in the form of grass, brush, timber and slash) to a minimum, so that if a tracer round shot from a weapon starts a fire, for example, they can contain it until they're done with their exercises and then put it out," Alvaré explained.
During these prescribed fires, the "burn boss" is in charge, assigning personnel to positions on a firing and a holding team. The firing team ignites designated areas with a drip torch, which dispenses a mixture of flaming fuel around the "line of black," the perimeter around the burn area that acts as a buffer zone to prevent the fire from escaping containment. The team then lights the head fire, the main fire that spreads quickly through the grass, leaf litter and other overgrowth.
