SPECIES COMPOSITION OF WEEDS IN THE VICINITY OF THE CITY OF PETROPAVLOVSK

Abstract

The paper deals with the distribution of weeds in the vicinity of the city of Petropavlovsk. The studied biotopes were selected based on the geographical location of the city. Each biotope is characterized by climate, soil, and anthropogenic factors. The total species composition was found to be 26 out of 337 studied specimens. In this work, special attention is paid to finding out the reasons for the active spread of weeds, relative to the territory. The number of species and their percentage ratio in the context of each biotope are determined, as well as the analysis is made and the reasons for the growth of certain representatives are established. Many of the weeds are found in several biotopes at the same time. Thus, the bird Highlander is noted in all the biotopes studied by us. Collected 31 copies or 9 % of the total. Levkovy jaundice from the Cabbage family was recorded in the Meshchansky forest and on the territory of the village of Solnechny with a total number of 23 specimens or 7%. The specified family was represented only by this representative.
