Which of the 7 ecoregions of Arkansas is the smallest in size?

Crowley's Ridge is the smallest ecoregion in Arkansas, characterized by its unique geological features and vegetation compared to the surrounding regions. This ridge is a prominent uplift that runs approximately 200 miles across the state, primarily in the eastern part of Arkansas.

In contrast, other ecoregions such as the Ouachita Mountains and the Arkansas River Valley are significantly larger in terms of land area. The Ouachita Mountains extend through the west-central part of the state and are known for their rugged terrain and mountainous landscapes, while the Arkansas River Valley encompasses a broad area surrounding the Arkansas River, featuring a mixture of agricultural land and forested areas.

The Mississippi Alluvial Plain, also larger than Crowley's Ridge, is defined by its vast, flat, and fertile land formed by the sediments deposited by the Mississippi River. Each ecoregion offers distinctive environmental characteristics, but Crowley's Ridge stands out as the smallest in size among them, making it significant from both ecological and geographical perspectives.
