Some amphibian species can escape, such as Pseudacris crucifer and P. cinereus . However, due to logistical constraints, we did not use this method. In fact, the drift fences held up well, and only some minor repairs using a staple gun and duct tape were necessary. In conclusion, the most efficient and effective method for locating amphibians in terrestrial habitats is pitfall arrays. Although installation is labor-intensive, once installed these provide the best means for trapping many species of amphibians.
Materials can be inexpensive and still reliable.
It is recommended that some method of searching be conducted with the trapping to increase the number of species recorded. Quadrat searching is best, because it disrupts less habitat and is better standardized than time-constrained searching. Integrating anuran amphibian species into environmental assessment programs.
