The increasing risks associated with forest fire emergency situations in forests necessitate exploring ways to enhance both overall forest fire protection and, in particular, fire-protection arrangements. Considering the specific features of forests of different purposes, including restrictions on logging in protection forests, one of the relevant tasks is a differentiated analysis of fire risks within such forests. Unlike production and forest reserves, protection forests — and especially specially protected forest areas — are usually spatially fragmented. The use of traditional information on forest fire locations, obtained from regional dispatch services based on aerial and ground observations, is hindered by the low accuracy of fire ignition coordinates (particularly in earlier years). The accumulation of large volumes of well-structured data from Earth remote sensing via space observations, independent of the human factor, has made it possible to obtain unique information for the comparative assessment of the share of forest fires occurring in forests of different purposes. It should be noted that geographically referenced data on the purpose of forests in the Russian Federation had previously not been available to the scientific community, and such a study at the national scale is being conducted for the first time. Because the costs of most fire-protection measures depend on area, an indicator such as fire-risk density (the share of forest fires occurring within a given area divided by the area of that territory) can be used at the planning stage to rationally allocate available resources among forests of different purposes. Recent trends show that this indicator in protection forests is significantly higher than in other categories (on average four times higher than in production forests and ten times higher than in forest reserves), although it has been decreasing at an average rate of –4 % per year. The corresponding increase in forest reserves is minor, though it is growing faster (+20 % per year) compared to production forests (+9 % per year). The results obtained in this study may be used to develop a scientifically grounded system of fire-protection arrangements and forest-fire prevention measures in forests of various purposes.
