Book Woody Fuel and Duff Consumption by Prescribed Fire in Northern Idaho Mixed Conifer Logging Slash

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.

Reinhardt and published by Forgotten Books. This book was released on 2017-11-18 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Woody Fuel and Duff Consumption by Prescribed Fire in Northern Idaho Mixed Conifer Logging Slash Because of these considerations, managers at tempt to remove specified amounts of fuel and also retain desired amounts of residual organic material. Consumption of fuels and retention of organic material can be described in several ways. Duff consumption is often described as depth reduction, percentage depth reduction, and percentage mineral soil exposure. For evaluating smoke emissions and nutrient capital, depth reduction is the appropriate expression because it describes actual amounts and can be converted to weight if duff bulk density is known. Percentage duff reduction is commonly used to describe fire prescription targets. It must be applied to preburn depth or loading to estimate actual amounts of duff removed or retained. Per centage mineral soil exposure relates to regenera tion potential, seedbed quality, and vulnerability to erosion. Objectives and constraints of prescribed fire can often be expressed as desired or acceptable levels of percentage mineral soil exposure. Consumption of woody fuel is often described as percentage of preburn fuel quantities consumed, especially for evaluating prescribed fire effects and designing fire prescriptions. It may be pre dicted initially as average diameter reduction of woody pieces and then converted to percentage volume reduction or fuel loading reduction.

Book Predicting Duff Consumption From Prescribed Burns on Conifer Clearcuts in Western Oregon and Western Washington Classic Reprint

Download or read book Predicting Duff Consumption From Prescribed Burns on Conifer Clearcuts in Western Oregon and Western Washington Classic Reprint written by Susan N. Little and published by Forgotten Books. This book was released on 2018-09-15 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Predicting Duff Consumption From Prescribed Burns on Conifer Clearcuts in Western Oregon and Western Washington The amount of duff consumed during a prescribed burn depends on the moisture profile of the duff and on the amount and duration of heat from the burning woody fuel. Duff will burn independently of heat provided by burning woody fuel at a moisture content of 30 percent (shearer The amount of heat needed to draw off moisture to that level depends, of course, on how wet the duff is before ignition. If a dry layer exists on the surface, it may reduce heat penetration in the duff pro file, and duff consumption will be dependent on fire duration.

Book Wildland Fuel Fundamentals and Applications

Download or read book Wildland Fuel Fundamentals and Applications written by Robert E. Keane and published by Springer. This book was released on 2014-11-04 with total page 195 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new era in wildland fuel sciences is now evolving in such a way that fire scientists and managers need a comprehensive understanding of fuels ecology and science to fully understand fire effects and behavior on diverse ecosystem and landscape characteristics. This is a reference book on wildland fuel science; a book that describes fuels and their application in land management. There has never been a comprehensive book on wildland fuels; most wildland fuel information was put into wildland fire science and management books as separate chapters and sections. This book is the first to highlight wildland fuels and treat them as a natural resource rather than a fire behavior input. Moreover, there has never been a comprehensive description of fuels and their ecology, measurement, and description under one reference; most wildland fuel information is scattered across diverse and unrelated venues from combustion science to fire ecology to carbon dynamics. The literature and data for wildland fuel science has never been synthesized into one reference; most studies were done for diverse and unique objectives. This book is the first to link the disparate fields of ecology, wildland fire, and carbon to describe fuel science. This just deals with the science and ecology of wildland fuels, not fuels management. However, since expensive fuel treatments are being planned in fire dominated landscapes across the world to minimize fire damage to people, property and ecosystems, it is incredibly important that people understand wildland fuels to develop more effective fuel management activities.

Book The Photoload Sampling Technique

Download or read book The Photoload Sampling Technique written by Robert E. Keane and published by . This book was released on 2007 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire managers need better estimates of fuel loading so they can more accurately predict the potential fire behavior and effects of alternative fuel and ecosystem restoration treatments. This report presents a new fuel sampling method, called the photoload sampling technique, to quickly and accurately estimate loadings for six common surface fuel components (1 hr, 10 hr, 100 hr, and 1000 hr downed dead woody, shrub, and herbaceous fuels). This technique involves visually comparing fuel conditions in the field with photoload sequences to estimate fuel loadings. Photoload sequences are a series of downward-looking and close-up oblique photographs depicting a sequence of graduated fuel loadings of synthetic fuelbeds for each of the six fuel components. This report contains a set of photoload sequences that describe the range of fuel component loadings for common forest conditions in the northern Rocky Mountains of Montana, USA to estimate fuel loading in the field. A companion publication (RMRS-RP-61CD) details the methods used to create the photoload sequences and presents a comprehensive evaluation of the technique.
