Canoes were used at night to spotlight and listen for anurans along four stretches of the Rio Grande in Big Bend National Park, Texas. Temporal and spatial variation in amphibian counts and species richness, as well as relationships between amphibian counts and environmental variables, in addition to amphibian-habitat associations along the banks of the Rio Grande were explored. Seven anuran species were documented, with Rio Grande leopard frogs (Rana berlandieri) making up 96% of the visual counts. The number of species detected varied on average by 37% across monthly and nightly surveys
