Abstract
The diversity of tundras and floodplain meadows in the northern part of Anabar plateau are revealed. It is represented by 5 associations and 3 subassociations, belonging to the 3 classes of eco-fl oristic classification. All associations (except one) and subassociations are described for the first time. The largest areas are occupied by swamped tundras (ass. Dryado incisae-Tomentypnetum nitensis ) and confined to the flattened parts of mountain terraces. Convex parts of the relief are characteristic for dryas tundras. In the upper part of goltsy altitudinal zone dominates dryas-lichen tundras (subass. Rhytidio rugosi - Dryadetum punctatae caricetosum misandrae ). Dryas crenulata tundras (аss. Carici melanocarpae - Dryadetum crenulatae ) dominate in the middle and lower parts of this zone. Meadow vegetation Anabar river floodplain is represented by two associations - Zigadeno sibirici-San guisorbetum offi cinalis and Lino perennis-Veronicetum longifoliae .
