The annotated list of mosses
of the Caucasian Reserve is published here for the first time. Moss flora
includes 332 species and 6 varieties of 45 families and 137 genera; 4 species
are new for Caucasus and 1 species – Hookeria lucens is new for Russia.
The Caucasian Reserve occupies the North and South macroslopes of the Western
Caucasus (36°45'–40°50'N, 43°30' – 44°05'E; 400 – 3360 m alt., area – 2816 sq.
km). The mountain massifs are formed by granites, shales and calcareous rocks
(limestones). The conspect includes habitat preferences for each species.
Abbreviations are used to show the occurrences of species in three geobotanic
regions: I – Sochi region (southern macroslope of Caucasus Range, faced to
Black Sea), II – Maikop region (northern macroslope of Caucasus, basin of
Belaya River); III – Labinsk region (northern macroslope, basin of the Laba
River) (Fig. 1). Also abbreviations refer to mountain belts as follow: MF –
middle mountain forest belt (broad-leaved forests at 400–800 m alt.); UF –
upper mountain forest belt (mixed coniferous—broad-leaved forests at 700–2000 m
alt.); SAF – subalpine forest belt (open birch and beech woodlands, pine and
maple forests at 1800–2200 m alt.); SA – subalpine belt, Rhododendron shrubs,
subalpine meadows and mires, at 1800–2400 m alt.); A – alpine belt (alpine
meadows and lichen heaths, mound and rock plant aggregations, 2200–3000 m alt);
the occurrence of species is abbreviated as follow: Un – unique; R – rare; Sp –
sporadic; Fr – frequently; Com – common.
