Abstract

The vegetation of the tundras and meadows of middle and lower reaches of the Anabar River represented by 4 classes, 8 associations and 3 subassociations of ecological-fl oristic classification. Seven associations and all subassociation described for the first time. A wide variety and large areas are occupied by the association of class LoiseleurioVac cinietea . Communities are part of polygonal tundra-bogs complexes, which are typical for flat watersheds (associations: Carici concolorisHylocomietum splendentis ass. nova hoc loco, ass. Pedicularido oederiAulacomnietum turgidi ass. nova hoc loco). Communities also occupy gentle slopes of the watershed hills (ass. Alectorio nigricantisDiapen sietum obovatae ass. nova hoc loco). Less diverse are snow meadows ( Eutremo edwardsiiSanionietum uncinatae ass. nova hoc loco and Saxifrago tenuisSalicetum polaris ass. nova hoc loco) and dryas tundras (ass. Rhytidio rugosiDry adetum punctatae Matveyeva 1998 ass. Rhodiolo roseaeAstragaletum alpini ass. nova hoc loco). Described a new alliance Carici concolorisAulacomnion turgidi. We put it in the class LoiseleurioVaccinietea . Communities of this alliance are stages of formation of the moss tundras from grassy bogs as a result of a cryogenic swelling of soil.
