Abstract
A specialist on the fire hazard in larch forest in permafrost areas of the Evenki Autonomous Okrug of East Siberia's Krasnoyarsk Kray examines the conditions leading to extreme fire outbreaks in the okrug, the periodicity of such extreme seasons, and the frequency and spatial distribution of blazes that result. Special attention is focused on how the information obtained can be used to increase the effectiveness of firefighting efforts by optimizing the allocation of firefighting resources and concentrating efforts in most important areas. An initial emphasis is on understanding why certain seasons are more hazardous than others, followed by an assessment of the expected frequency of such periods and the locations most likely to be adversely affected.
