Characterizing the Jack Pine-black Spruce Fuel Complex of the International Crown Fire Modelling Experiment (ICFME)


Book Description

This report describes in detail the various sampling methods & techniques used in quantifying the ground, surface, ladder, and crown or canopy fuel characteristics of the jack pine & black spruce forest in the primary plots of the International Crown Fire Modelling Experiment, located about 50 kilometres north-east of Fort Providence, Northwest Territories. The approach involved both general sampling in the study area as a whole and the use of a systematic grid structure for the experimental plots that were to be burned. New data & information on the fuel properties of northern forests were acquired as part of this process. Detailed descriptions & summaries of the char of the forest floor, dead-down woody surface fuels by roundwood diameter size class, understory canopy ladder fuel, and overstory crown fuel for each of the primary plots are presented in tabular & graph form. Representative values for the fuel complex represented by the study area forest cover type are also given.

Ecological Silvicultural Systems


Book Description

ECOLOGICAL SILVICULTURAL SYSTEMS Unleash the natural power and adaptability of forests with this cutting-edge guide For generations, silvicultural systems have focused largely on models whose primary objective is the production of timber, leading to drastically simplified forests with reduced ecological richness, diversity, and complexity. Ecological silviculture, by contrast, focuses on producing and maintaining forests with “all their parts”—, that is, with the diversity and flexibility to respond and adapt to global changes. Ecological silviculture seeks to emulate natural development models and sustain healthy forests serving multiple values and goals. Ecological Silvicultural Systems provides a comprehensive introduction to these approaches and their benefits tailored to diverse types of forests, designed for forest management professionals. It provides a series of exemplary models for ecological silviculture and surveys the resulting forest ecosystems. The result is a text that meets the needs of professionals in forestry and natural resource management with an eye towards sustaining healthy forest ecosystems, adapting them to climate change, protecting them from invasive species, and responding to changing market forces. Ecological Silvicultural Systems readers will also find: Detailed treatment of forest ecosystems in North America, Europe, South America, and Australia A broad field of contributors with decades of combined expertise on multiple continents Discussion of pine woodlands; temperate hardwood forests, boreal forests, temperate rainforests, and more Ecological Silvicultural Systems is a useful reference for professional foresters, wildlife habitat managers, restoration ecologists, and undergraduate and graduate students in any of these fields.




Wildland Fire Behaviour


Book Description

Wildland fires have an irreplaceable role in sustaining many of our forests, shrublands and grasslands. They can be used as controlled burns or occur as free-burning wildfires, and can sometimes be dangerous and destructive to fauna, human communities and natural resources. Through scientific understanding of their behaviour, we can develop the tools to reliably use and manage fires across landscapes in ways that are compatible with the constraints of modern society while benefiting the ecosystems. The science of wildland fire is incomplete, however. Even the simplest fire behaviours – how fast they spread, how long they burn and how large they get – arise from a dynamical system of physical processes interacting in unexplored ways with heterogeneous biological, ecological and meteorological factors across many scales of time and space. The physics of heat transfer, combustion and ignition, for example, operate in all fires at millimetre and millisecond scales but wildfires can become conflagrations that burn for months and exceed millions of hectares. Wildland Fire Behaviour: Dynamics, Principles and Processes examines what is known and unknown about wildfire behaviours. The authors introduce fire as a dynamical system along with traditional steady-state concepts. They then break down the system into its primary physical components, describe how they depend upon environmental factors, and explore system dynamics by constructing and exercising a nonlinear model. The limits of modelling and knowledge are discussed throughout but emphasised by review of large fire behaviours. Advancing knowledge of fire behaviours will require a multidisciplinary approach and rely on quality measurements from experimental research, as covered in the final chapters.




Large Outdoor Fire Dynamics


Book Description

Large Outdoor Fire Dynamics provides the essential knowledge for the hazard evaluation of large outdoor fires, including wildland, WUI (wildland-urban interface), and urban fires. The spread of outdoor fires can be viewed as a successive occurrence of physical and chemical processes – solid fuel combustion, heat transfer to surrounding combustibles, and ignition of heated combustibles – which are explained herein. Engineering equations frequently used in practical hazard analyses are derived and then integrated to implement a computational code predicting fire spread among discretely distributed combustibles. This code facilitates learning the procedure of hazard evaluation for large outdoor fires. Chapters cover underlying assumptions for analyzing fire spread behavior in large outdoor fires, namely, wind conditions near the ground surface and fundamentals of heat transfer; the physical mechanism of fire spread in and between combustibles, specifically focusing on fire plumes (both reacting and non-reacting) and firebrand dispersal; and the spatial modeling of 3D objects and developing the computational framework for predicting fire spread. The book is ideal for engineers, researchers, and graduate students in fire safety as well as mechanical engineering, civil engineering, disaster management, safety engineering, and planning. Companion source codes are available online.




Fire on Earth


Book Description

Earth is the only planet known to have fire. The reason is both simple and profound: fire exists because Earth is the only planet to possess life as we know it. Fire is an expression of life on Earth and an index of life’s history. Few processes are as integral, unique, or ancient. Fire on Earth puts fire in its rightful place as an integral part of the study of geology, biology, human history, physics, and global chemistry. Fire is ubiquitous in various forms throughout Earth, and belongs as part of formal inquiries about our world. In recent years fire literature has multiplied exponentially; dedicated journals exist and half a dozen international conferences are held annually. A host of formal sciences, or programs announcing interdisciplinary intentions, are willing to consider fire. Wildfire also appears routinely in media reporting. This full-colour text, containing over 250 illustrations of fire in all contexts, is designed to provide a synthesis of contemporary thinking; bringing together the most powerful concepts and disciplinary voices to examine, in an international setting, why planetary fire exists, how it works, and why it looks the way it does today. Students, lecturers, researchers and professionals interested in the physical, ecological and historical characteristics of fire will find this book, and accompanying web-based material, essential reading for undergraduate and postgraduate courses in all related disciplines, for general interest and for providing an interdisciplinary foundation for further study. A comprehensive approach to the history, behaviour and ecological effects of fire on earth Timely introduction to this important subject, with relevance for global climate change, biodiversity loss and the evolution of human culture. Provides a foundation for the interdisciplinary field of Fire Research Authored by an international team of leading experts in the field Associated website provides additional resources







From Fires to Oceans: Dynamics of Fire-Derived Organic Matter in Terrestrial and Aquatic Ecosystems


Book Description

Fire-derived organic matter, also known as pyrogenic carbon (PyC), is ubiquitous on Earth. It can be found in soils, sediments, water and air. In this wide range of environments, fire-derived organic matter, represents a key component of the organic matter pool, and, in many cases, the largest identifiable group of organic compounds. PyC is also one of the most persistent organic matter fractions in the ecosystems, and its study is, therefore, particularly relevant for the global carbon cycle. From its production during vegetation fires to its transfer into soils, sediments and waters, PyC goes through different transformations, both abiotic and biotic. Contrary to early assumptions, PyC is not inert and interacts strongly with the environment: evidence of microbial decomposition, oxidation patterns and interactions with minerals have been described in different matrices. PyC travels across these different environments and it is modified chemically and physically, but remains persistent. This Research Topic explores important questions in our understanding of fire-derived organic matter, from the characterization and quantification of PyC components, to the transformation and mobilization processes taking place on terrestrial and aquatic ecosystems. The studies compiled here provide novel and, often, unexpected results. They all answer some of the questions posed and, more importantly, provide scope for many more.




Fire Phenomena and the Earth System


Book Description

Fire plays a key role in Earth system processes. Wildfires influence the carbon cycle and the nutrient balance of our planet, and may even play a role in regulating the oxygen content of our atmosphere. The evolutionary history of plants has been intimately tied to fire and this in part explains the distribution of our ecosystems and their ability to withstand the effects of natural fires today. Fire Phenomena and the Earth System brings together the various subdisciplines within fire science to provide a synthesis of our understanding of the role of wildfire in the Earth system. The book shows how knowledge of fire phenomena and the nature of combustion of natural fuels can be used to understand modern wildfires, interpret fire events in the geological record and to understand the role of fire in a variety of Earth system processes. By bringing together chapters written by leading international researchers from a range of geological, environmental, chemical and engineering disciplines, the book will stimulate the exchange of ideas and knowledge across these subject areas. Fire Phenomena and the Earth System provides a truly interdisciplinary guide that can inform us about Earth’s past, present and beyond. Readership: Advanced students and researchers across a wide range of earth, environmental and life sciences, including biogeochemistry, paleoclimatology, atmospheric science, palaeontology and paleoecology, combustion science, ecology and forestry.
