Amphibian survey wraps up

An 8-month amphibian survey of the Las Vegas Wash and Clark County Nature Preserve concluded in October.

The survey identified two anuran species, the Woodhouse’s toad, native to Southern Nevada, and the American bullfrog, an invasive species.

Surveys were conducted by two biologists scanning appropriate habitats with spotlights at night. Although both species were identified during surveys of both areas, toads were the most common species found across revegetation areas along the Wash and bullfrogs were the most common species found in the streams and ponds of the Nature Preserve.
