Analysis of the invasive activity of Cotoneaster lucidus Schlecht. in the Kalinovsky forest park in Yekaterinburg

Abstract

The article is devoted to a comprehensive analysis of Cotoneaster lucidus Schlecht. in the forest park area of Yekaterinburg (Russia) based on population (age and vitality structure) and organismal parameters (morphometric indicators). The purpose of the study is to analyze the invasive activity of Cotoneaster lucidus Schlecht. in the Kalinovsky Forest Park in Yekaterinburg. Plants in the habitat are presented in the form of geoxyl bush. In the Age structure, two periods have been identified - pregenerative and generative, and six ontogenetic states. All habitats are at the stage of colonization, exclusively in forb pine forests with a canopy density of 0.6-0.7. The main route of penetration of the brilliant cotoneaster into the Kalinovsky Forest Park is artificial plantings along the paths, near equipped recreation areas. Its spread was facilitated by the presence of edible, long-lasting fruits on the shoots, which provided food for many species of birds. The established features indicate the high potential of the species and successful naturalization.
