Wildlife of
Rostovskaja oblast'

Pontic-Caspian steppe landscapes: feather-grass and fescue steppe, dry forb-rich grasslands, and disturbed steppe on fertile black soils; much is now cropland with remnant steppe patches and ravine/gully grasslands.

Dominant biome across most of the oblast (roughly ~70-85%), especially away from major river floodplains and the coast.

Large lowland river systems and reservoirs centered on the Don River (including the lower Don reach), tributaries, channels, oxbows, and major impoundments such as the Tsimlyansk Reservoir; supports fish migration routes and floodplain waters.

Linear network throughout; highest density along the Don and major tributaries/reservoirs (~5-10% as water and immediate riparian zone, but ecologically influential beyond its area).

Floodplain wetlands and deltaic reedbeds (Don delta), seasonally inundated meadows, oxbow marshes, and brackish/saline wetlands in lowlands; critical for waterbirds and nursery habitats for fish.

Patchy but extensive in the lower Don floodplain and delta and around lowland basins (~3-8%, locally much higher near the delta).

Northeastern Sea of Azov coastal waters and nearshore shallows, including brackish conditions influenced by river discharge; supports coastal lagoons, nearshore feeding areas for birds, and fisheries.

Limited to the Azov coastline and nearshore zone of the oblast (small proportion of total area, ~1-3% including nearshore waters).

Scattered riparian broadleaf stands, floodplain woods, and planted shelterbelts/forest strips within an otherwise open steppe matrix; natural forests are largely confined to moister river valleys and ravines and gullies.

Minor and fragmented (~1-5%), concentrated along river floodplains, ravines, and planted windbreak networks.

Feather-grass (Stipa) and fescue steppe remnants, ravine/gully grasslands, and dry forb meadows; many intact patches persist in protected areas and less-plowed gullies.

Secondary grasslands on abandoned fields and pastures, plus meadow-steppe transitions on moister soils; often a mosaic with shrubs and weedy species.

Shrubby ravines and steppe gullies with hawthorn/rose and other shrubs, forming refugia and corridors in agricultural landscapes.

Extensive croplands on fertile black soils (grain, sunflower and other field crops) dominating the steppe; high habitat conversion with field margins and shelterbelts providing limited structure.

Lower Don River and tributaries with channels, backwaters, and oxbows; key migration and spawning corridor for fishes and a major ecological backbone of the oblast.

Large reservoirs and lake-like expansions (notably Tsimlyansk Reservoir) plus smaller lowland lakes and coastal lagoons; variable salinity in some basins.

Floodplain wet meadows, reedbeds and sedge wetlands, seasonally flooded depressions, and delta wetlands in the lower Don system.

Reed and cattail marshes in the Don delta and floodplain oxbows; important breeding/stopover habitat for waterbirds.

Don delta/estuarine mixing zone where freshwater inputs meet brackish Azov conditions, creating productive nursery habitats and dynamic sediment channels.

Low, shallow Azov coast with brackish lagoons and coastal wetlands; sensitive to water-level and salinity changes.

Sandy and shell beaches/spits along the Sea of Azov shoreline, often adjacent to lagoons and reedbeds.

Shallow Azov seafloor with soft sediments (sand/silt) supporting benthic invertebrate communities that underpin coastal food webs.

Small patches of floodplain broadleaf woods (e.g., willow-poplar and other riparian deciduous stands) along riverbanks and in moist depressions.

Highly fragmented natural and planted tree cover including riparian forests, shelterbelts, and small groves; provides nesting/roosting sites and windbreak structure in open landscapes.

Rostov-on-Don and other cities/industrial areas with riverfront habitats, parks, and altered shorelines.

Peri-urban country-house plots, garden plots, and low-density settlements forming a gradient of disturbed greenspace along river terraces and transport corridors.
