- Underwater landscape
A complex of aquatic and wetland vegetation and no less diverse fauna develops in the Kalchik River and its tributaries. The organisms that live in the river have adapted to their habitat. The bottom of the river is silty with sandy shoals, consisting of granite chips. The main ecological groups of organisms in water bodies are plankton and benthos in the form of phyto – and zoobenthos. The hydrofauna is represented by freshwater fauna. Of the higher aquatic plants, the Kalchik River is characterized by reed, cattail, horn-leaved plants, and duckweed near the banks.

- Threats to ecology
The upper and middle reaches of Kalchik is polluted by salts washed away from agricultural territories, in the lower reaches of the Mariupol household wastewater. An increased content of oil products and non-volatile phenols is observed in water.
Water salinity increases from source to mouth. Near the mouth, mineralization reaches 2.5 g/l.
