Abstract
Based on expeditionary work in the period 2003–2018 we compile a map of linden forests locations in the Jewish Autonomous Region (JAR). An inventory map of forest fires was created using data on forest fire registration of the Forest Management Department of the JAR Government for 2017–2020. The number, area, and configuration of the burned areas were determined by superimposing of these maps. The analysis of fire-damaged forests shows that during the study period fires were observed in all forest formation with linden. Their total number was 174. The most of fires (33%) noted in 2018 and the fewest (15%) – in 2017. The average annual number of fires in 2017–2020 was 44. The largest area affected by the pyrogenic factor was observed in 2018. The smallest area (7.5%) of linden forests were fire-transformed in 2020. The average area of one fire is 653 hectares. This corresponds to 64% of the total fire-affected area in the studied vegetation formations. The black birch and oak park-type forests, sometimes with linden, larch, with silverspike-and-forbs cover and forbs-and-pinegrass meadows were most affected by fire. We analyzed the spatial distribution of the fire-damaged forests and established its main patterns as well as identified the areas of repeated burnout. In the most of the JAR linden forests fires have a one-time character. Local areas are subject to multiple burnout; the causes of their high multiple ignition require further study. In this regard, forest fires is a factor that significantly contributes to the reduction of the honey-bearing lands of the JAR.
