The results of vegetation classification of protective forest stands in the southern and central regions of the Rostov region using the method are presented J. Baun-Blaquet. The syntaxonomy is based on 75 complete geobotanical descriptions obtained during route surveys of the territory. As a result, 7 associations were identified, including 3 new ones: Padello mahaleb-Fraxinetum excelsioris - unites communities of protective and priovrazhy protective forest plantations (ZLN) in the southern districts of the Rostov region, with dominants in the first tree tier Fraxinus excelsioris and Padellus mahaleb - in the shrubby, as part of the Chelidonio majoris-Robinion pseudoacaciae; Elytrigio repentis-Ulmetum minoris - communities of ZLN bordering the bayrach forests of the southern and central regions of the Don region, the first tree tier is dominated by Ulmus minor, a sodominant in the herbage of Elytrigia repens; Elytrigio repentis-Fraxinetum excelsioris - communities of wide (up to 40 m) ZLN along federal highways, shore-strengthening ZLN of the central and southern regions of the studied region. The peculiarity of the last two associations is the predominance of natural flora species in the stand, however, all the described communities artificially created plantings in the 60-70s, they are attributed to the alliance Chelidonio majoris-Acerion negundi. Validation of the alliance Chelidonio majoris-Acerion negundi and association Chelidonio majoris-Aceretum negundi was also carried out.
