A classification system of the Colchic spruce-fir forests (the Western Caucasus) was developed using the Brawn-Blanquet method. Two new associations Dryopterido caucasicae–Abietetum nordmannianae ass. nov., Pruno laucerasi–Abietetum nordmannianae ass. nov. and new alliance Dryopterido caucasicae–Abietion nordmannianae all. nov. were proposed after the comparative syntaxonomic analysis of dark coniferous forests from the Euxine province. Diagnostic species of the alliance are Acer pseudoplatanus, Actaea spicata, Athyrium filix-femina, Dentaria bulbifera, Dryopteris carthusiana, D. filix-mas, Fagus orientalis, Geranium robertianum, Gymnocarpium dryopteris, Impatiens noli-tangere, Oxalis acetosella, Paris incompleta, Polystichum aculeatum, Ranunculus grandiflorus, Rubus caucasicus, Salvia glutinosa, Symphytum grandiflorum. All described Colchic associations and alliance were placed in the order Abieti nordmannianae– Piceetalia orientalis Coban et Willner 2019 and the class Asaro europaeai–Abietetea sibiricae Ermakov et al. in Willner et al. 2016 uniting West Palearctic dark coniferous subnemoral forests from Europe, Asia Minor, Southern Urals and Western Siberia.

Ермаков Н.Б., Плугатарь Ю.В., Лейба В.Д. Леса Abies nordmanniana и Picea orientalis из Колхидского региона (Западный Кавказ) и новая концепция классификации эвксинских темнохвойных лесов в системе Брауна-Бланке. Классификационная система елово-пихтовых лесов Колхиды (Западный Кавказ) разработана с использованием метода Браун-Бланке. Две новые ассоциации: Dryopterido caucasicae–Abietetum nordmannianae ass. nov., Pruno laucerasi–Abietetum nordmannianae ass. nov., и новый союз Dryopterido caucasicae–Abietion nordmannianae all. nov. предложены в результате сравнительного синтаксономического анализа темнохвойных лесов Эвксинской провинции. Диагностические виды союза: Acer pseudoplatanus, Actaea spicata, Athyrium filix-femina, Dentaria bulbifera, Dryopteris carthusiana, D. filix-mas, Fagus orientalis, Geranium robertianum, Gymnocarpium dryopteris, Impatiens noli-tangere, Oxalis acetosella, Paris incompleta, Polystichum aculeatum, Ranunculus grandiflorus, Rubus caucasicus, Salvia glutinosa, Symphytum grandiflorum. Все описанные колхидские ассоциации и союзы отнесены к порядку Abieti nordmannianae–Piceetalia orientalis Coban et Willner 2019 и классу Asaro europaei–Abietetea sibiricae Ermakov et al. in Willner et al. 2016, объединяющему темнохвойные субнеморальные леса Западной Палеарктики (Европы, Малой Азии, Южного Урала и Западной Сибири).
