Assistant Fire Management Officer, Eldorado National Forest, Placerville, Calif.; Soil Scientist, Pacific Southwest Forest and Range Experiment Station, Forest Service, U.S. Department of Agriculture, Glendora, Calif. Abstract: The use of prescribed fire in the chaparral could reduce the incidence and impacts of severe wildfires and enhance watershed resources. This paper describes the operatio...

Forest fire-potential is natural disaster that breaks out strongly , destructs largely and is difficult to dispose and rescue, its destructive power has a serious threat to the security of society and human living environment, moreover, it does greatly damage to natural ecological environment. Therefore, the study on forest fire prediction and prevention is a main job. In fact, it is complicate...

Forest fires have major impact on ecosystems and greatly impact the amount of greenhouse gases and aerosols in the atmosphere. This paper presents an overview in the forest fire detection, emission estimation, and fire risk prediction in China using satellite imagery, climate data, and various simulation models over the past three decades. Since the 1980s, remotely-sensed data acquired by many ...

Although forest fires are commonly accepted as a natural part of the ecosystem, frequent forest fires present great challenges to fire managers. In this research, ‘Fire Area Simulator’ has been used to simulate and study forest fire behaviour. Once the predicted perimeters were generated and compared to those shown in postmortem aerial infrared images, partial agreement was observed for the dir...

Wireless sensor network have a broad range of applications in the category of environmental monitoring. In this paper, the problem of forest fire is considered and a comprehensive framework is proposed for the use of wireless sensor networks for real-time forest fire detection and monitoring. The wireless sensor network unlike that of traditional approaches, can easily forecast forest fires bef...

Fire modeling is used to understand and to predict possible fire behavior without getting burned. Fire models are used in different aspect of fire management. The increase in the number of forest fires in the last few years has forced governments to take precautions. Beside prevention, early intervention is also very important in fire fighting. If the fire fighters know where the fire will be i...

Lightning fire is the dominant natural disturbance of the western mixedwood boreal forest of North America. We quantified the independent effects of weather and forest composition on lightning fire initiation (a detected and recorded fire start) patterns in Alberta, Canada, to demonstrate how these biotic and abiotic components contribute to ecosystem dynamics in the mixedwood boreal forest. We...

This paper presents a summary of the forest fire reports in the insular Caribbean derived from both management reports and an analysis of publicly available Moderate Resolution Imaging Spectrodiometer (MODIS) satellite active fire products from the region. A vast difference between the amount of fires reported by land managers and fire points in the MODIS Fire Information for Resource Managemen...

Fire-dependent pine forests in the Caribbean Basin cover extensive areas in the coastal plain of the Caribbean Sea and Gulf of Mexico and on several islands in the Bahamas Archipelago, Cuba, Hispaniola, and the Honduran Bay islands. These forests are high in conservation value but, unfortunately, remain mostly unprotected. Moreover, even though they are fire dependent, the use of fire for fores...
