The current state of coenotic populations of rare and endangered species of
Uzbekistan Helichrysum maracandicum is given. The range of species distribution
is broad. The article contains 12 cenopopulations of Helichrysum
maracandicum in Uzbekistan, which have considerable healing properties.
During the researches, no censorship marks were recorded in any cenopopulation.
Approximately, 1, 5, 11 censorpopulations were found to be close
to optimal conditions. This indicates that adequate amounts of precipitation
in these areas throughout the year have a positive impact on the growth and
development of the plant. Most of the cenopopulations were transmitted to
younger and transient states.
