MAVLake/Obion countiesDyer Co.Tipton Co.Shelby Co.

Location:  Lauderdale County is bordered to the north by Dyer County, to the east by Crockett and Haywood counties, to the south by Tipton County, and to the west by Mississippi County, Arkansas. Within the county, the Mississippi River travels 46.7 river miles (river miles 820.0 - 773.3).
Physiographic Area:  PIF 05 (Mississippi Alluvial Valley); BCR 26 (Mississippi Alluvial Valley)

Description:  The MAV in Lauderdale County from the Dyer County line angles southwest up to around a 12-mile path that narrows to a tip at the Tipton County line at the mouth of the Hatchie River. Public wildlife lands within the MAV in Lauderdale County total around 51,495 acres--Chickasaw Wildlife Management Area (25,006), Cold Creek Refuge (2,018),  John Tully Wildlife Management Area (12,493), Lauderdale Refuge (657), Lower Hatchie National Wildlife Refuge (9,451), and Sunk Lake State Natural Area (1,870). The Lauderdale Refuge lies within the East Gulf Coast Plain, but is included with the MAV because of its close proximity to it. There are no sizeable towns within the MAV in Lauderdale County. Ripley is the county seat.

Ornithological Importance:  A significant portion of the MAV in Lauderdale County is under wildlife management. Included here are the federally and Tennessee endangered Least Tern with one major nesting colony--Nebraska Point Dikes (see Lauderdale County summary below and Least Tern Surveys in the Mississippi River for a state-wide summary); raptors including the In Need of Management in Tennessee Mississippi Kite; bottomland species among them the In Need of Management in Tennessee Cerulean Warbler; one of the largest blocks of bottomland hardwood forest in Tennessee; wading birds by the hundreds; shorebirds by the hundreds; waterfowl by the tens of thousands; and neotropical migrants and wintering species. Documentation is contained in Chickasaw NWR, Lauderdale Refuge, Lower Hatchie NWR,  the Least Tern sites, and the notes below.
