Once vital to fire prevention and detection, most of the Black Hills National Forest historic lookout towers now serve primarily as hiking destinations. The first crude lookout structures were built at Custer Peak and Harney Peak in 1911. Since that time, more than 20 towers have been constructed in the area. The first lookout towers were built of wood, most replaced by steel or stone. The Civilian Conservation Corps was instrumental in constructing fire towers during the 1930s and 1940s. One of the most famous and architecturally and aesthetically valued towers is the Harney Peak Fire Lookout–situated on the highest point east of the Rocky Mountains. Harney Peak is among a number of Black Hills towers listed on the National Historic Lookout Register. Over 200 vintage images tell the story of not only the historic fire towers but those who manned them. Perched atop high peaks in remote locations, fire lookout personnel spent countless hours scanning the forest, pinpointing dangers, often experiencing the powerful wrath of lightning strong enough to jolt them off their lightning stools.

Remote sensing has been widely used in active forest fire detection; however there are some limitations in the operational contextual algorithms. These algorithms are greatly affected by clouds and different land cover types such as land and water with inherent temperatures. This book, therefore, provides a new multi-temporal threshold algorithm for near real-time forest fire detection using geostationary satellites, supplemental to the existing algorithms. This algorithm is based on temperature in IR3.9 channel and the difference between IR3.9 and IR10.8 channels. The multi-temporal threshold algorithm proved to have higher fire detection rate (50%) as compared to MSG FIR-G (3.7%) when ground data from Portugal was used for validation. This superiority was also confirmed over Southern Africa when MODIS fire product was used for validation. This analysis shows the possibility of manipulating the temporal domain of geostationary satellites in monitoring highly temporal environmental phenomenon. This algorithm could be especially useful to professionals in forest fire management, or anyone else who may be interested in applying geostationary satellites in environmental monitoring.

A forest fire is any uncontrolled, non-structure fire that occurs in the wilderness. Wildlife behavior is often complex and variably dependent on factors such as fuel type, moisture content in the fuel, humidity, wind speed, topology, geographic location and ambient temperature. Weather patterns, such as heat waves droughts can also have a dramatic impact on the onset and outcome of wildfires. Fire is sometimes essential for forest regeneration, however, it often destroys forests and has dire social and economic consequences. This book looks at the underlying causes of forest fires, their ecological effects and preventive strategies.1982nd Edition

Tran Van Nao (Editor) The last decade has witnessed a seriously increasing incidence of forest fires in many countries. Substantial economic and ecological losses have been incurred, although the estimation of total damage This has been due to the lack assessment has often been inaccurate. of standardized methods for collecting data on fire occurrence and area burnt, as well as information such as the value of the vegetation destroyed and restoration costs, and the implications for recreation, tourism and other social activities. The Mediterranean region was initially considered one of the most vulnerable to forest fires because of its' dry climate and strong winds. No region is immune to forest fires, however, and damage has been especially severe in areas where pine is the predominant species. Although forest fires are normally considered a national problem, they become an international one when they occur in border area forests or when the ecological impacts are felt over long distances. The potential for forest fires exists in every country -unless it is a complete desert - and for this reason, there is a need to promote better understanding of the fires, and closer cooperation between countries in controlling them.
