Year: 2019, Number: 4, Pages: 5-21

In article the history of studying of flora of the reserve is briefly stated and results of repeated inventory of flora of vascular plants of the considered territory are presented. The basis for the inventory was the herbarium materials of the authors collected on the territory of the reserve in 2009 – 2016. According to the results of the inventory, the species composition of the reserve flora was identified, numbering 741 species of vascular plants from 330 genera and 94 families. It was established that for the period from 1986–2016, the flora of the reserve was replenished with 106 species of vascular plants (91 native and 15 alien), including 6 rare species – Asplenium ruta-muraria, Carex conspissata, Cypripedium ventricosum, Iris laevigata, Gastrolychnis saxatilis, Listera savatieri and 4 endemic species Aquilegia barykinae, Calamagrostis amurensis, Eritrichium jacuticum and Taraxacum woroschilovii, 2 of which – Taraxacum woroschilovii and Aquilegia barykinae are narrow local endemics of the Tukuringra ridge. The growth in the territory of the reserve of 4 species of vascular plants was not confirmed by modern collections – Dimorphostemon pectinatus, Lamium barbatum, Poa reverdattoi and Viola mauritii. The revealed changes in specific structure of flora of the reserve are connected with expansion of northern border of the reserve in 1986, the introduction of alien species on the southern border of the reserve (highway Zeya city – Zolotaya Gora village) and also the influence of the Zeyskaya hydroelectric power station reservoir on vegetation of a coastal zone.
