PHYSOCARPUS OPULIFOLIUS (L.) MAXIM. (ROSACEAE) ON THE LEFT BANK OF UKRAINE: DISTRIBUTION, ECOLOGICAL AND COENOTIC PECULIARITIES

Abstract

The article summarizes the data on the distribution of the alien species Physocarpus opulifolius (L.) Maxim. on the territory of the Left Bank of Ukraine. It is established that the species is common cultivated and partly escaped in this region. The author found 29 locations of Physocarpus opulifolius in the Forest and Forest-Steppe zones (three – within Kyiv city, 12 – in Kyiv region, 10 – in Poltava region, two – in Sumy region, two – in Cherkasy region and the one – in Chernihiv region). In other hand the species has not been found in the wild in Kharkiv, Dnipropetrovsk and Donetsk regions, as well as in the Steppe zone in general. The author indicated all known localities of Physocarpus opulifolius (except for cultural places of distribution) on the Left Bank of Ukraine, supplementing his findings with the data from literature sources. Based on the analysis of original geobotanical releves it was found that Physocarpus opulifolius rarely occurs as a concomitant species in three associations: Salicetum capreae Schreier 1955 (alliance Sambuco-Salicion capreae Tüxen & Neumann ex Oberdorfer 1957 from the order Sambucetalia racemosae Oberdorfer ex Doing 1962 and the class Urtico-Sambucetea Doing 1962), Chelidonio-Pinetum sylvestris (Gorelov 1997) Davydov 2019 (alliance Balloto nigrae-Robinion pseudoacaciae Hadač & Sofron 1980 from the order Chelidonio-Robinietalia pseudoacaciae Jurko ex Hadač & Sofron 1980 and the class Robinietea Jurko ex Hadač & Sofron 1980) and Impatienti parviflorae-Robinietum Sofron 1967 (alliance Chelidonio-Robinion pseudoacaciae Jurko ex Vitková 2013 from the order Chelidonio-Robinietalia pseudoacaciae and the class Robinietea). The author also describes shrub communities with Physocarpus opulifolius as a diagnostic and dominant species to new association Elymo repenti-Physocarpetum opulifolii Davydov, belonging to the class Robinietea.
