Catastrophic forest fires in 2010 affected about half of the largely anthropogenically transformed territory of the Kerzhensky Nature Reserve. As a result of many years of research, it has been established that the flora of the part of the reserve affected by fires includes at least 320 plant species and is distinguished by a smaller proportion of alien species than the flora of the entire reserve. Some species were recorded in areas affected by fires only in the first two years after the fire; several species found before 2010 were not recorded after the fire. As much as 15 species are reported to be potentially invasive.
