The "Kovalivski Plavni" hydrological reserve has been established in the Olshanska community of Mykolaiv Oblast. Covering an area of 394 hectares east of the village of Kovalivka, this valuable wetland ecosystem—home to unique flora and fauna—will now be protected under the territory’s nature reserve status.
This was reported by the Ukrainian Nature Conservation Group (UNCG).
To protect the floodplains of the Southern Bug River from human interference, the Olshanska community initiated the creation of the reserve back in 2024. At the request of UNCG, the Mykolaiv Regional Council supported this initiative with its decision.

Uniqueness of the area
The new reserve contains floodplain lands in the Southern Bug valley and serves as an important wetland area.
According to the UNCG, several rare species of higher aquatic vegetation have been discovered here. In particular, these include natural communities of yellow water lilies and white water lilies – both listed in the Green Book of Ukraine.
Among the diverse plant life of the “Kovalivski Floodplains,” conservationists also found floating salvinia, a species of fern that is rather rare in southern Ukraine.
The floodplain ecosystem, with its characteristic vegetation, attracts typical wetland bird species, including several rare representatives.
“Some of the animal species found here are included in the Red Data Book of Ukraine, the regional red list, and the Bern Convention,” the Ukrainian Nature Conservation Group reported.
EcoPolitic previously covered the preparation of a government decree intended to protect Ukraine’s marshes and peatlands from destruction due to intensive land use.
