Nearly half of these species - 415 (42.96%) occur frequently and in large quantities. 59 species (6.11%) occur frequently or are common species in the Danube Delta. 345 (35.71%) rare species have been found in large quantities. 137 (14.18%) species occur rarely with a small number, and 10 (1.04%) have been found in less than ten locations.

With a height of several hundred meters Kiliyskaya Danube Delta looks boundless with the expanse of the common reed Phragmites australis. Inland waters for the most part are covered with water chestnut floating communities, white lily Nymphaea alba, yellow capsule Nuphar lutea, and bolototsvetnika schitolistogo Nymphoides peltata. Along the edge of the shore towns and ordinary watercourses strip air-water vegetation of trostnoka ordinary Phragmites australis, Typha uzkolistogo Typha angustifolia, Typha broad-T. latifolia, Sparganium erectum direct ezhegolovnika etc.
The vegetation in the area is different depending on the location of the site since the DBR is expansive and includes coastal areas, river channels and other variations. The northern part of the reserve is dominated by marsh, saline marsh and meadow vegetation types. The south is made up mostly of large areas of trees and shrubs, water and marsh. The east hosts large populations of psammophytic halophytic, and the west, mostly swamp forest.
The vegetation of the reserve is a holistic natural complex represented by communities of different types of organizations that are genetically different from each other: water, marsh, meadow, and forest. They are formed and developed under the influence of natural and anthropogenic processes in the Danube Delta. The main factors determining their location and spatial relationship, is the hydrological regime of the Danube and the nature of the interaction of the Danube waterways and the sea.
The vegetation of the reserve can be divided into four main territorial complexes that are associated with the historical and spatial development of the territory. This plavnevo-littoral complex secondary mouth of the Danube Delta Kilia, arenas Zhebriyanskoy ridge plavnevy Stentsovsko-Zhebriyanovskih marshes and meadow marsh islands Ermakova. This has resulted in reservoir Sasyk becoming the most impoverished in the floristically aquatic ecosystem.
Species richness of ecotopes are not directly based on their areas of the reserve. So, in wetland ecosystems, which represent about 70% of the territory, they are growing only 68 types of bog species (sixth in total), with 50 species growing on non-saline marshes, and 18 - in saline.
The first place is occupied by the species richness of synanthropic species - 363 (including adventive) species, however, the reserve area occupied by them are small (about 2%), and mostly abandoned land of gardens and three islands - Islands Ermakov, and Shabosh Prorvin that have undergone the greatest changes due to human activity. Changes in the natural state of these islands is primarily due to human activities, with shipping and its attendant manifestations - the dumping of dredging soil on the coastal ecosystems of the islands.
Grassland ecotopes represent the largest number of native species of plants - 288, among which, 234 species are characteristic of freshwater meadows, and 54 for saline. By area, this group of ecotypes is only the third place (7%) after the marsh and water.
Third place for the kinds of ecotopes steppe (139). The area of the steppe vegetation in the reserve iws the lowest (less than 1%). It is fourth in the number of species and the area occupied by sand spread ecotopes (about 5%). In fifth place are water ecotopes (69 species). However, by footprint (about 20%), they are second only to the marsh. A smaller number of species are salt licks and salt . Forest ecotopes in the Danube Delta consists of 23 species of trees and shrubs. The area occupied by them are almost identical. However, forest Zhebriyanskoy strands -an artificial ecosystem where Crimean pine plantations dominated. Forests on the islands priustevyh areas consist primarily of native species of white willow and brittle, and of spits - out of the bushes (buckthorn, Loja, tamarisk, etc.).
Background plants must also distribute the habitat.

The largest area with flooded vegetation are long smoother sections of Phragmites australis, Schoenoplectus lacustris L., Typha angustifolia, Carex riparia, C. extensa, C. distans, C. otrubae Podp., C. acutiformis, Calystegia sepium (L.) R. Br., Salix cinerea, etc., and continuously flooded areas - Phragmites australis, Carex elata All., C. pseudocyperus L., C. acuta L., C. vesicaria L., Typha angustifolia, T. latifolia L., Glyceria maxima (C. Hartm.) Holmb., Acorus calamus, etc.
Aquatic vegetation in different types of the water reserve are different depending on the influence of the sea (salinity) and the speed of the water flow. The largest area is occupied by fresh water, in which the background species are Sparganium erectum, L. Nymphaea alba, Nuphar lutea (L.) Smith, Trapa natans, Stratiotes aloides L., Salvinia natans, Hydrocharis morsus-ranae, Spirodela polyrrhiza, Lemna minor, Ceratophyllum demersum L., Myriophyllum spicatum L. Potamogeton nodosus Poir., Potamogeton crispus L., Potamogeton perfoliatus L. and others. Brackish water species are include Ceratophyllum demersum, Potamogeton pectinatus L., Zannichellia palustris, Z. pedunculata Reichenb.
Most important though are the seaside tumors, namely new coastal sandy islands and open waters and shallow waters around the islands. These are areas in which there are processes of speciation and morphogenesis. This area has the highest concentration of live organisms during migration, breeding, spawning and nursery areas.
