Vascular plant species of Turukhansky Raion and Evenkiysky Raion (Krasnoyarsk krai, Russia)

This paper presents the first inventory of vascular plant species occurring in the Turukhansky and Evenkiysky municipal districts (raions) of Krasnoyarsk Krai, Russia. The checklist was compiled from published sources, observations from the iNaturalist platform, and herbarium materials, primarily collected within the Central Siberian Biosphere Nature Reserve, Tunguska Nature Reserve, and, partly, the Putorana Nature Reserve, as well as adjacent areas. Both native and alien (adventive) species are included, with the latter comprising 76 species, reflecting the comparatively low level of anthropogenic disturbance in the region. The checklist also identifies species occurring at the northernmost or southernmost limits of their distribution in the study area. It includes 60 species listed in the Red Data Book of Krasnoyarsk Krai, seven of which are also included in the Red Data Book of the Russian Federation. In total, 1,316 species (including 13 hybrids) belonging to 383 genera and 88 families have been recorded across the two raions, including 771 species in Turukhansky and 1,171 in Evenkiysky. The higher species richness of the Evenkiysky Raion is associated with its substantially larger area (nearly four times that of Turukhansky) and its more complex landscape structure, comprising both lowland and mountainous terrain and, consequently, supporting a greater diversity of vegetation.
