Fire Management Considerations
Some managers believe that prescribed fire may be a useful silvicultural tool for managing red spruce on some sites. On such sites, the exposed mineral soil must have plentiful moisture, soil temperatures must be moderate, and competition must be minimal . In general, however, fires in red spruce habitat are of little silvicultural value . Slash burning following logging kills advance reproduction and creates rank postfire vegetation that delays any new seedling establishment . The fire management plan for Acadia National Park, Maine, dictates the suppression of natural fires. Prescribed fires may be used on occasion to reduce fuels . Patterson and others  estimated fuel loadings for a number of stands in Acadia National Park that contained red spruce. They concluded that fire exclusion was probably resulting in increased fuel loads. Alexander  compiled slash fuel indices for red spruce and compared actual fire spread, intensity, and slash and organic layer depletions with those predicted by the Canadian Forest Fire Danger Rating System. Freeman and others  developed equations to determine average crown weight per tree as a function of tree height and diameter for use in a method to predict slash weight after logging red spruce.
