Ouachita Mountains
The Ouachita Mountains dominate the landscape of west-central Arkansas. Unlike the dissected plateaus of the Ozarks, they are composed primarily of highly folded and fractured rocks that form east-west trending ridges and valleys. There are several geologic subregions within the Ouachitas, but in general they are made up of alternating exposures of sandstones and shale, and have little of the limestone influence that characterizes the Ozarks. Consequently, the numerous spring and seep wetlands in the Ouachitas support different plant communities than most Ozark wetlands in similar settings. As in the Ozarks, many wetlands of the Ouachitas have been affected by agriculture and development.

Representatives of all of the wetland classes occur within the Ouachitas. Read more about Wetland Classification, or find information on specific wetland classes that occur in the Ouachita Wetland Planning Region:
