The interactions of forest fires and air-flow are highly nonlinear. The heat and moisture supplied through the burning of ground and canopy fuel during a forest fire create extreme levels of buoyancy forcing. The horizontal gradients of buoyancy produce vortices, or fire whirls, of tornado strength. For these reasons, foresters, ecologists, land managers, geographers, and environmental scientists are interested in the behavior and ecological effects of fires. This book will be the first to focus on the chemistry and physics of fire as it relates to the ways in which fire behaves and the impacts it has on ecosystem function. This book concerns the different aspects of forest fires, the impact of fire on both forest resources (e.g. forest cover) and communities that use different forest functions. Therefore, forest fires have their environmental, economic and social consequences, and none of them is less important. Forest fires can be caused by both natural forces and anthropogenic factors, and in the latter case, it is extremely . Jul 04, · Forest Fires forestry Because the major economic importance of the forest lies in wood and wood products, forestry has been chiefly concerned with timber management, especially reforestation, maintenance of the extant forest stands at prime condition, and fire control.
Even before the myth of Prometheus, fire played a crucial ecological role around the world. Numerous plant communities depend on fire to generate species diversity in both time and space. Without fire such ecosystems would become sterile monocultures. Recent efforts to prohibit fire in fire dependent communities have contributed to more intense and more damaging fires.3/5(1). A forest fire is an uncontrolled fire in a forest or area of woodland. It can wreak havoc across large area, pose a threat to the forest wealth seriously disturbing the bio-diversity, ecology and the environment of a region. Forest fire can cause by natural or human activities. Interagency Standards for Fire and Fire Aviation Operations Interagency Standards for Fire and Fire Aviation Operations- single PDF file.

Oct 25, · Wildfires thin forest canopies and undergrowth, allowing sunlight to reach the forest floor and a new generation of seedlings to grow. In fact, some species of trees, like sequoias, rely on fire. Forest fires are large uncontrolled fires that take place in the forest. Some of the fiercest fires occur in the forest because there is so much fuel (trees) to burn. Forest fires are a type of wildfire. Other types of wildfires include grass fires, brush fires, and hill fires. Major Causes of Forest Fires. Wildfires. A raging wildfire can be a major disaster, costing lives and destroying homes. But fires in nature can help as well as harm, clearing forests of dead trees and allowing young plants to grow. Breathtaking photos highlight this surprising look at fire's part in maintaining the balance of nature.5/5(1). Forest fires prediction combines weather factors, terrain, dryness of flammable items, types of flammable items, and ignition sources to analyze and predict the combustion risks of flammable items in the forest. Forest fire prediction has developed rapidly in various countries in the world since its inception in the s.
