Jennifer Barnes, NPS-Alaska Fire Ecologist and Eric Miller, BLM-Alaska Fire Ecologist talk about duff moisture sampling in Alaska: why we do it, its history, and comparing field results of destructive sampling and oven drying to weather-generated Duff Moisture Code and Drought Code of the Canadian Forest Fire Danger Rating System. They show data gathered by an intensive interagency collaboration around the state. The Alaska experience with duff moisture and fire differs in some important respects from the Canadian and Alaska has more trouble interpreting DC because of effects of regional differences in duff thickness over a vast area and permafrost, among other things.
