It includes one of the largest and richest carp fishpond complex in Croatia overgrown with lush wetland vegetation, as well as wet pastures and ponds along Sava River. These wetland habitats are ornithologically the most valuable part of the area. The prevailing habitat is intensively used arable land.
The most valuable forest habitat is here the alluvial oak forest Mrsunjski lug. The area is important for breeding and wintering of waterbirds and the most important stop-over site of Cranes.
