Download or read book Woody Fuel and Duff Consumption by Prescribed Fire in Northern Idaho Mixed Conifer Logging Slash written by and published by . This book was released on 1991 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental burns were conducted on 36 plots in mixed conifer logging slash in northern Idaho to investigate consumption of duff and woody fuel. Prescribed fires were conducted in spring and fall, in YUM (yarded unmerchantable material) and non-YUM clearcuts and seedtree cuts. Preburn and postburn fuel loadings were measured, and fuel moistures were sampled shortly before burning. Preburn duff depth ranged from 1.2 to 2.6 inches. Preburn woody fuel loadings ranged from 28 to 86 tons/acre. Sixty-four percent of the duff was consumed. Most of the small woody fuel was consumed, along with an average of 15.5 tons/acre of large woody fuel. Postburn mineral soil exposure averaged 66 percent. Residual loading of large woody fuel averaged 31 tons/acre. Methods for predicting duff and woody fuel consumption are reported. For predicting percentage of duff reduced, the best independent variables were shallow duff moisture content and unit average diameter reduction of large woody material. For predicting duff depth reduction, the best independent variables were average duff moisture content and preburn duff depth. Diameter reduction of large woody fuel was best predicted using moisture content and average preburn diameter as independent variables. Guidelines are included for fire prescription development. These include recommendations for amounts of fuel to retain and to consume and discussion of tradeoffs in setting fire objectives. Equations are presented for computing moisture contents.

Download or read book Postfire Mortality of Ponderosa Pine and Douglas fir written by James F. Fowler and published by . This book was released on 2004 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: This review focused on the primary literature that described, modeled, or predicted the probability of postfire mortality in ponderosa pine (Pinus ponderosa) and Douglas-fir (Pseudotsuga menziesii). The methods and measurements that were used to predict postfire tree death tended to fall into two general categories: those focusing on measuring important aspects of fire behavior, the indirect but ultimate cause of mortality; and those focusing on tissue damage due to fire, the direct effect of fire on plant organs. Of the methods reviewed in this paper, crown scorch volume was the most effective, easiest to use, and most popular measurement in predicting postfire mortality in both conifer species. In addition to this direct measure of foliage damage, several studies showed the importance and utility of adding a measurement of stem (bole) damage. There is no clear method of choice for this, but direct assessment of cambium condition near the tree base is widely used in Douglas-fir. Only two ponderosa pine studies directly measured fine root biomass changes due to fire, but they did not use these measurements to predict postfire mortality. Indirect measures of fire behavior such as ground char classes may be the most practical choice for measuring root damage. This review did not find clear postfire survivability differences between the two species. The literature also does not show a consistent use of terminology; we propose a standard set of terms and their definitions.
