摘要

A form for a register of populations of rare and endangered plant species is given. The special form consisting of 19 items is worked out to characterize the populations. A characteristic of the species composition and populations listed in the register is given. The register includes 70 local populations of 38 species, composed of 88 coenopopulations. 20 species are endemic to the Urals, 8 species are relict, 8 species are endangered due to transformation of their habitats, 7 species are ornamental, and 3 species are medical. 2 species were included in the Red Data Book of the RSFSR (1988), and 24 species in the Red Data Book of the Middle Urals (1996). 82 of 88 coenopopulations were referred to as standard, and 6 as control ones.
