The IBA extends c.40 km from north to south and comprises mudflats in the Huang He (Yellow River) in Heyang County. The Huang He river channel is becoming wider in this region, because of reduced flow rate and increased sedimentation. This has resulted in the extensive growth of reedbeds in the area, which are favourable breeding habitats for waterbirds.
