Grand Rivers Corridor

The Grand Rivers Corridor encompasses more than 513,000 acres in the watersheds of the Cumberland.


Why the Conservancy Selected This Site

The Grand Rivers Corridor encompasses more than 513,000 acres in the watersheds of the Cumberland and Tennessee Rivers below their dams at Land Between the Lakes. This includes all of Livingston County and parts of Caldwell, Crittendon, Lyon, Marshall and McCracken Counties.

Important systems in the area include aquatic assemblages of the Cumberland and Tennessee Rivers, sloughs and emergent wetlands, bottomland forest, oak flatwoods, forested ravines, non-hydric oak savannah, native grasslands and xeric glade communities. There are a number of rare federally threatened or endangered plant and animal species present.

Threats

Current land use in the area is largely agricultural with 60% open land, 34% forested and 6% developed -- but urban development represents a growing threat to its biodiversity. Other threats include lack of fire management in both woodland and grassland systems, poorly planned silvicultural activities, wetland alteration, and runoff that is degrading water quality.

Our Conservation Strategy

Conservation targets for the area include rare or declining species listed above in glades, prairies, grasslands, wetlands, water, and karst areas and cave systems. 

What the Conservancy Has Done/Is Doing

The Nature Conservancy is working with representatives from Quail Unlimited, the Kentucky Division of Forestry, Kentucky Department of Fish and Wildlife Resources, and the Nature Resources Conservation Service. Working with numerous private landowners and local governments will be extremely important. Westvaco is recognized as a large landowner in the area and a potential conservation partner for this landscape.
