Important Note! It is not the intention of this writer to teach researchers and others how to climb into the forest canopy. This article is intended as a means of acquainting those who may already be exploring the forest canopy with the idea that there are available techniques for climbing of which they may be unaware, or of which they may be aware but not utilizing. Those wishing to climb into...
Forest fires are one of the most important factors that threaten the ecological balance in the countries that are affected by the Mediterranean climate such as Turkey. Forests, that constitute 1⁄4 of the total area of our country, are in great danger of fire, especially during summer period. In 74,294 forest fires, we lost 1,630,000 hectares of forest area since 1937. This area is three times l...
To ensure remote sensing MODIS hotspot (also known as active fire products or hotspots) quality and precision in forest fire control and management in Thailand, an increased level of confidence is needed. Accuracy assessment of MODIS hotspots utilizing field survey data validation is described. A quantitative evaluation of MODIS hotspot products has been carried out since the 2007 forest fire s...

Mauricio Acuna, Cristian Palma, Wenbin Cui, David Martell *, Andres Weintraub Universidad de Chile, Santiago “Integrated timber harvest and fire management planning” Harvest planners often consider potential fire losses and timber production plans can influence fire management but mo...
Fire and insects are natural disturbance agents in many forest ecosystems, often interacting to affect succession, nutrient cycling, and forest species composition. We review literature pertaining to effects of fire-insect interactions on ecological succession, use of prescribed fire for insect pest control, and effects of fire on insect diversity from northern and boreal forests in North Ameri...
The forest-savanna ecotone may be very sharp in fire-prone areas. Fire and competition for light play key roles in its maintenance, as forest and savanna tree seedlings are quickly excluded from the other ecosystem. We hypothesized a tradeoff between seedling traits linked to fire resistance and to competition for light to explain these exclusions. We compared growth- and survival-related trait...
The Pacific fisher (Martes pennanti) is a rare forest carnivore strongly associated with dense, old forest with high canopy cover for denning and resting. The Sierra Nevada population is very small, genetically distinct, and isolated. Mixed-severity wildland fire is assumed to be a potentially greater threat than logging, and land managers are conducting large-scale forest thinning operations u...
Forest fire is a common disturbance factor, especially in boreal forests. The detection of forest disturbance and monitoring of post-fire forest recovery are crucial to both ecological research and forest management. The Greater Hinggan Mountain area of China is rich in forest resources, but also has a high incidence of forest fires. After the most serious forest fire in the history of P. R. Ch...
Forests play a critical role in sustaining the human environment. Most forest fires not only destroy the natural environment and ecological balance, but also seriously threaten the security of life and property. The early discovery and forecasting of forest fires are both urgent and necessary for forest fire control. This article explores the possible applications of Spatio-temporal Data Mining...
Forest fire or wild land fire causes adverse ecological, economic and social effects worldwide. Globally, forest fires are considered as one of the major drivers of climate change having deleterious impacts on the earth and environment as studies reveal their significance in producing large amounts of trace gases and aerosol particles, which play a pivotal role in tropospheric chemistry and cli...
