This book was released on 2001 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire managers are increasingly concerned about the threat of crown fires, yet only now are quantitative methods for assessing crown fire hazard being developed. Links among existing mathematical models of fire behavior are used to develop two indices of crown fire hazard-the Torching Index and Crowning Index. These indices can be used to ordinate different forest stands by their relative susceptibility to crown fire and to compare the effectiveness of crown fire mitigation treatments. The coupled model was used to simulate the wide range of fire behavior possible in a forest stand, from a low-intensity surface fire to a high-intensity active crown fire, for the purpose of comparing potential fire behavior. The hazard indices and behavior simulations incorporate the effects of surface fuel characteristics, dead and live fuel moistures (surface and crown), slope steepness, canopy base height, canopy bulk density, and wind reduction by the canopy. Example simulations are for western Montana Pinus ponderosa and Pinus contorta stands. Although some of the models presented here have had limited testing or restricted geographic applicability, the concepts will apply to models for other regions and new models with greater geographic applicability.

Book excerpt: Fire managers are increasingly concerned about the threat of crown fires (CF), yet only now are quantitative methods for assessing CF hazard being developed. Links among existing mathematical models of fire behavior are used to develop two indices of CF hazard -- the Torching Index & Crowning Index. These indices can be used to coordinate different forest stands by their relative susceptibility to CF & to compare the effective. of CF mitigation treat. The coupled model was used to simulate the wide range of fire behavior possible in a forest stand for the purpose of comparing potential fire behavior. The concepts will apply to models for other regions & new models.

Book Synopsis Optimum Timeframes for Detecting Songbird Vocalizations in the Black Hills by : Todd R. Mills
Download or read book Optimum Timeframes for Detecting Songbird Vocalizations in the Black Hills written by Todd R. Mills and published by . This book was released on 2000 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: Birds are indicators of vegetation structure and ecological conditions. The singing activity of birds declines during late-morning periods, which can affect estimates of abundance and conclusions regarding vegetative conditions indexed by birds. Therefore, it is important to quantify periods of bird activity so biologists can plan studies. We determined hourly detections from singing males of 22 nongame bird species in ponderosa pine, quaking aspen, and grassland vegetation types in the Black Hills of South Dakota. Detections of 12 of 22 species differed among 1-hr intervals after sunrise. Detections of yellowrumped warblers, Townsend's solitaires, red-breasted nuthatches, western tanagers, and American robins decreased on count-episodes more than 4 hrs after sunrise. Detections of dusky flycatchers declined on count-episodes more than 3 hrs after sunrise and detections of black-capped chickadees were greatest during the first hour after sunrise and declined afterward. Detections of many other species from songs or calls decreased on count-episodes more than 5 hrs after sunrise. We recommend that bird counts in the Black Hills be completed within 4 hrs after sunrise so estimates of bird abundance are not affected by reduced singing among males.

Book Synopsis A Strategic Assessment of Crown Fire Hazard in Montana by :
Download or read book A Strategic Assessment of Crown Fire Hazard in Montana written by and published by . This book was released on 2004 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: Estimates of crown fire hazard are presented for existing forest conditions in Montana by density class, structural class, forest type, and landownership. Three hazard reduction treatments were evaluated for their effectiveness in treating historically fire-adapted forests (ponderosa pine (Pinus ponderosa Dougl. ex Laws.), Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), dry mixed conifer) that rate high/moderate for fire hazard. Comprehensive restoration treatments that address density, structure, and species composition of high-hazard forests are significantly more effective at reducing hazard than thin-from below approaches that remove smaller trees only. Trees removed as a byproduct of the restoration treatment yielded net revenues averaging over $600 per acre, whereas the thin-from-below approach would require an out-of-pocket expenditure of over $600 per acre. Posttreatment conditions were projected forward 30 years and reevaluated for hazard. Projections revealed that effectiveness of all treatments diminished over time; however, forests receiving the comprehensive restoration treatment remained substantially lower hazard 30 years after treatment than they would have had they received the alternative treatments.
Book Synopsis Vegetation of the Glacier Lakes Ecosystem Experiments Site by : Claudia M. Regan
Download or read book Vegetation of the Glacier Lakes Ecosystem Experiments Site written by Claudia M. Regan and published by . This book was released on 1998 with total page 546 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vegetation at the Glacier Lakes Ecosystem Experiment Site, a 600 ha research site at 3200 to 3500 m elevation in the Snowy Range of southeastern Wyoming, was categorized and described from an intensive sampling of species abundances. A total of 304 vascular plant taxa were identified through collection and herbarium documentation. Plots with tree species were separated from those without tree species for ordination and classification analyses. Detrended correspondence analysis was used to order plots along major axes of composition variation, which are inferred moisture and topographic gradients. Cluster analysis was used to categorize plots based on composition similarity. The resulting groups were named according to species dominants. We identified and described in detail 4 meadow, 4 thicket or scrub, 3 krummholz, and 2 forest plant associations.
Book Synopsis Modelling, Monitoring and Management of Forest Fires II by : G. Perona
Download or read book Modelling, Monitoring and Management of Forest Fires II written by G. Perona and published by WIT Press. This book was released on 2010 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: As in the past, future forest fire scenarios are impacted by climatic trends and changes in climatic extremes, as well as by anthropic pressure. It is to be expected that future trends, especially in the Mediterranean regions, will certainly lead to an increasing impact of human pressure on the natural environment, due to increases in tourism and to the enlargement of urban residential areas invading the countryside. Forecasting the effects of both factors (climatic and anthropic) and separating their effects on forest fires frequencies may be particularly difficult, but is essential to improve our knowledge of forest fire occurrence probability and to better organize prevention and fighting activities. At the same time, estimation of the possible increase of fire risk over coming years is important, taking into account also the diverse fire prone environments present in the Mediterranean as well as many other areas (mountain slopes, coastal zones, large islands, etc). This book contains peer-reviewed papers presented at the Second International Conference on Modelling, Monitoring and Management of Forest Fires held in Kos, Greece, in 2010. The papers covered important topics in the field of prevention and fighting of forest fires, including: Computational Methods and Experiments; Air Quality and Health Risk Models; Detection, Monitoring and Response Systems; Decision Support Systems; Resource Optimization; Risk Assessment and Vulnerability Assessment.
