Yakima River Delta Wildlife Nature Area

Latitude, Longitude: 46.246469, -119.255605

The unit is mainly river floodplain land supporting extensive stands of woody riparian growth, most of which is Russian olive (E. angustifolia). Recently wildlife habitat on the southeastern portions of this unit was developed and improved. This included the clearing of Russian olive, seeding of food plots, providing a vehicle control and parking, installing signs, and developing a 1½-mile nature trail. Future development will include additional tree clearing, seeding, vehicle control, and parking areas.
