SYNTAXONOMY OF ANTROPOGENIC FOREST COMMUNITIES OF THE LEFT BANK FOREST-STEPPE OF UKRAINE

Abstract

Results of the phytosociological research of antropogenic forest communities of the Left Bank Forest-Steppe of Ukraine were summarized in this paper. Author found that the names Robinietea pseudoacaciae Jurko ex Hadač & Sofron 1980 and Chelidonio majoris-Robinietalia pseudoacaciae Jurko ex Hadač & Sofron 1980 widely accepted by various authors were invalidly published in 1980 so both these names have been validated to preserve their current use. The class Robinietea pseudoacaciae Jurko ex Davydov cl. nov. includes the one order Chelidonio majoris-Robinietalia pseudoacaciae Jurko ex Davydov ord. nov., two alliances (Balloto-nigrae-Robinion pseudoacaciae and Chelidonio majoris-Robinion pseudoacaciae) and six associations. Three associations are new: the first of them is Chelidonio majoris-Pinetum sylvestris (Gorelov 1997) ass. nova et stat. nov., the name in a new rank proposed for previously descibed subassociation Chelidonio-Robinietum pinetosum sylvestris Gorelov 1997 (the vegetation of pine forest plantations), the second one is Elymo repentis-Robinietum pseudoacaciae ass. nova, the correct name against invalidly published name Elytrigio repentis-Robinietum pseudoacaciae Smetana 2002, the third association is Poo angustifoliae-Fraxinetum pennsylvanicae ass. nova including for the vegetation of forest plantations dominated by Fraxinus penssylvanica. Nomenclatural types, original publications, data about chorology and ecology of studied communities are indicated for all syntaxa.
