Download or read book Economic Efficiency of Fire Management Programs at Six National Forests written by Dennis L. Schweitzer and published by . This book was released on 1982 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two components of fire management programs were analyzed at these Forests: Francis Marion (South Carolina), Huron-Manistee (Michigan), San Bernardino (California), Tonto (Arizona), and Deschutes and Willamette (Oregon). Initial attack and aviation operations were evaluated by the criterion of minimizing the program cost plus the net value change of resource outputs and structures resulting from fire (C + NVC). Four alternative program or budget levels were investigated at each forest for each of 3 years of varying fire severity. The program levels ranged from +20 percent below the 1979 funding level to 40 percent above that level. The most economically efficient levels were -20 percent at four forests, +20 percent at one forest, and +40 percent at another forest. Results suggested that increased fire year severity may not mean that a higher program level is more efficient. Commercial timber and structural losses contributed most to net value change, which was a small percent of the C + NVC in most of the years evaluated.

Available in PDF, EPUB and Kindle. Book excerpt: In a 1964-1967 study on the Challenge Experimental Forest, seedfall was evaluated in 2-, 5-, and 10-acre circular clearcuttings. During the 4 years, 10 seed crops, ranging from light to bumper, were produced by ponderosa pine. white fir, Douglas-fir, and incense cedar. Seedfall ranged from 76 to 40,691 sound seed per acre (188 to 100,547/ha) for a single species in a given year. From 89 to 100 percent of each species' seed fell within an area 1 1/2 times the height of the average dominant tree. Overall, seed distribution was highly variable.

Download or read book Wildland Fire Management Economics written by Jennifer Beverly and published by . This book was released on 1994 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Provides a general overview of recent research related to wildland fire economics and decision support systems. After an introduction, section two describes the general evolution of concepts and approaches relative to wildfire economics in its historical context. Section three summarizes a major state of the art review of wildland fire management by Baumgartner and Simard, 1982. Section four updates that work with an overview of selected research and analysis conducted since 1982. Section five synthesizes the material discussed in the previous sections, and section six is an annotated bibliography of 26 studies and reports selected to represent the spectrum of issues in fire economics which have been provided in the literature since 1982. The final section contains a more complete listing of citations obtained through an electronic search of the TREE CD database.

Book excerpt: Data that represent average worst fire weather for a particular area are used to index daily fire danger; however, they do not account for different locations or diurnal weather changes that significantly affect fire behavior potential. To study the effects that selected changes in weather databases have on computed fire behavior parameters, weather data for the northern Rocky Mountains were treated as probability distributions, then used in computer simulation to estimate distributions of rate-of-spread (ROS) and fireline intensity (FLI). Sensitivity of ROS and FLl to weather input changes was analyzed by varying the source and amount of weather data, and diurnally adjusting temperature and relative humidity. In eight representative cases, a minimum amount of data produced the lowest cumulative probabilities of ROS and FLl, and data from a higher elevation produced the highest values. For long-term planning, within the region studied, a small subset of weather data distributions was adequate for estimating probabilistic distributions of ROS and FLI. Joint probabilities of ROS and FLI differed substantially among test cases. Fire behavior values obtained with observed data were higher than those obtained with diurnally adjusted data. The simulation techniques used are appropriate for use in long-term fire management planning models.
