Abstract
The data were taken both from the literature and from research under natural conditions. Stabilization of a list of rare and disappearing species of the Ukraine dendroflora and establishment of their category were included. Present-day studies should involve the protection efficiency for certain species and the extent of their habitats under protection. Certain species have disappeared from a number of physicogeographical zones of the Ukraine. Organization of protection for locus classicus of certain plants was discussed.
