Trend Data Atchafalaya Occupancy Monitoring VES/VOC: Acris blanchardi, Anaxyrus fowleri, Gastrophryne carolinensis, Hyla chrysoscelis, Hyla cinerea, Hyla squirella, Incilius nebulifer, Lithobates catesbeianus, Lithobates clamitans, Lithobates grylio, Lithobates sphenocephalus, Pseudacris crucifer, Pseudacris fouquettei ( American Bullfrog, Blanchard's Cricket Frog, Cope's Gray Treefrog, Eastern Narrow-mouthed Toad, Fowler's Toad, Green Frog, Green Tree Frog, Pig Frog, Southern Leopard Frog, Spring Peeper, Squirrel Treefrog)
Location: Boat Sites South of I-10 ; Boat Sites South of I-10
The primary goal here is to accomplish long-term monitoring of the diverse anuran assemblage in this large bottomland hardwood area using visual encounter surveys with concurrent vocalization surveys. Additional research questions centered on the effects of changes in hydrology will also be addressed.

Location: Below Saltwater Barrier ; Below Saltwater Barrier
The goal of this study is to monitor anuran occupancy using standard protocols while also recording salinities, as this area is below a saltwater barrier on the Neches River and is susceptible to saltwater encroachment during tropical storm surges or periods of drought, which may impact anuran occupancy. We also added 20 sites north of the saltwater barrier as reference sites in 2012.
