Comparing Jack Pine Slash and Forest Floor Moisture Contents and National Fire Danger Rating System Predictions

摘要

Relations between certain slash and forest floor moisture contents and the applicable estimated timelag fuel moistures of the National Fire Danger Rating System were investigated for 1-year-old jack pine fuel types in northeastern Minnesota and central Lower Michigan. Only approximate estimates of actual fuel moisture are possible for the relations determined, thus emphasizing the need for on-site measurements when fuel moisture may be critical.
