Herpetofaunal Biogeography of the Ouachita Region

  The diversity of herpetofauna (amphibians & reptiles) of the Ouachita region is quite interesting and unique.  The geological history, climate and weather, along with it's location (primarily as part of the Southeast, but with influences from the Southwest and Great Plains) provides for a wide biogeographical mix of species.  Also, because the region developed differently geologically than the larger ecoregions around it, allowed for endemic species to evolve.

Amphibians & Reptiles
of Lake Ouachita (Garland & Montgomery Counties), Arkansas

  Amphibians & reptiles are some of the most interesting and important animals in Arkansas.  They play vital roles in ecosystems & consume many insects, and harmful crop pests & rodents.  These unique animals have been part of the natural history of the State for thousands of years, but many species are now disappearing from the landscape of Arkansas.

Helpful Reminders: It is important to know that all native animals and plants are protected on U.S. Army Corps of Engineers & U.S. Forest Service public lands in the Lake Ouachita region.  Additionally, a number of rare and endangered species occur in the area.  Observe and appreciate animals from a distance, but please do not harass or try to capture them.  Trying to capture or feed wildlife can be harmful to both you and the animal.  Many animals lose their fear of humans when people feed them, which can lead to dangerous encounters.  Safely observing or photographing animals ensures their survival.  Public lands are some of the few remaining relatively undisturbed areas in Arkansas that provide habitat and homes for many species.  For more information, visit our website below.  Please do your part to preserve and protect the awesome, natural biodiversity of Arkansas!

(Above) Aquatic salamanders of Lake Ouachita.

Aquatic salamanders are some of the most unique and interesting species in the Southeast & Arkansas.  These odd looking salamanders are aquatic permanent larvae that have lost the ability to transform into adults.  They possess external gills or gill slits and are often stream-lined or adapted for an aquatic life.  Many people may mistake them for freshwater eels.  They are carnivorous and consume live prey & reach a size of 4-42+ inches.  At least four species are found in Arkansas, with three occurring in the Lake Ouachita region.
