FUEL REDUCTION EFFECTIVENESS:
– “Fuel Treatments and Fire Severity: A Meta-Analysis” – “Thinning treatments have demonstrated the greatest reductions in wildfire severity, but only by those treatments that produce substantial changes to canopy fuels, shift the diameter distribution towards larger trees, and are followed by broadcast burning or other means of removal. Until the residual activity fuels are disposed, they will largely offset much of the hazard reduction benefit achieved from opening the canopy. … Modifications in fire behavior achieved within a single treated stand, however significant, are unlikely to change the total area burned by a large wildfire, aid fire control efforts, or impact the distribution of severities across a landscape (Finney and others 2003). Fuel treatment effectiveness ultimately depends on the cumulative impact of a treatment regime applied across landscapes and maintained through time.”
–> Note: This cessation of treatments is what resulted from the 80-90% reduction in NF harvest levels. This cessation is a primary factor in the increase in wildfire (documented repeatedly in other posts on NCFP) acres burned since the harvest reduction policy was instituted after 1990 at the behest of those opposed to sound forest management – it’s called shooting yourself in the intestines.
–> Note: This is a combined statistical analysis of various controlled experiments wherein the model referred to is the normal statistical model used to test a hypothesis for significance of the independent variables.
