Abstract

Invasions of alien species have become a global problem worldwide. Our paper presents the results of the study of the chorology of the invasive species Ambrosia artemisiifolia L. within the Right-Bank Forest-Steppe of Ukraine (RBFSU). We identified 13 new growth areas in the study area. These studies cover the observation and recording of the phenological behaviour of this species during 2020-2021. Although phenological observations are mainly carried out on cultivated plants, the data obtained as a result of the study is an important resource for preparing an invasive species control plan. Based on the indicators of temperature fluctuations, drought tolerance, light tolerance, relation to soil fertility, reproduction and shoot regeneration of A. artemisiifolia, a scoring method was proposed using the coefficient of complex adaptive potential (CCAP). However, our work is a pioneering study aimed at counteracting the spread of alien plants.
