Comprehensive analysis of the state of habitats of Cotoneaster lucidus Schlecht. in the Malo-Istoksky forest park in Yekaterinburg

Abstract

The article is devoted to a comprehensive analysis of Cotoneaster lucidus Schlecht. in the forest park area of the city of Yekaterinburg (Russia) based on population (age and vitality structure) and organismal parameters (morphometric indicators). The purpose of the study is to analyze the features of the ontogenetic and vitality structure of seven habitats of the brilliant cotoneaster Cotoneaster lucidus Schlecht in the Malo-Istoksky forest park of the city of 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 three ontogenetic states. All habitats are young and are in the stage of settlement, exclusively in forb pine forests with a canopy density of 0.3-0.6. The main route of penetration of the brilliant cotoneaster into the Malo-Istoksky 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. © The Authors, published by EDP Sciences.
