Dniprovsko-Orilskyi Nature Reserve, Nature reserve in Dnipropetrovsk Oblast, Ukraine

Dniprovsko-Orilskyi Nature Reserve is a protected area spanning wetlands, floodplain forests, and sandy steppes across the Dnieper and Oril river valleys in Dnipropetrovsk Oblast. The reserve covers approximately 3.8 thousand hectares with landscapes shaped by water and seasonal flooding patterns.

The reserve was created in 1990 by combining two earlier protected sites: the zoological sanctuary at Taromski Plavni and the ornithological refuge at Obukhivski. This merger established a larger continuous zone for safeguarding the river floodplains and their wildlife.

The reserve's name links the Dnieper River and the Oril, whose old channel, the Protovcha, forms the floodplain it protects. Its oak groves of black maple are listed in Ukraine's Green Book, and the floodplain is the only protected area of its kind in Dnipropetrovsk Oblast.

The reserve is a strict nature reserve: mass recreation, construction, hunting and fishing are prohibited, so visits are tied to scientific study rather than tourism. Its 3,766 hectares lie in Dnipro Raion, with a 50-metre buffer along the Dnieper Reservoir and a 3,125-hectare protected zone. The directorate sits in the research building on the Obukhivka settlement council territory.

The reserve's bird list grew from 171 species recorded in the Russian-language survey to 196 species across 1991–2021, grouped into six ecological complexes: wetland, forest, meadow, synanthropic, steppe and forest-edge scrub. The 50-metre buffer along the Dnieper Reservoir adds 3,125 hectares to the 3,766-hectare core.
