Woodhouse’s Toad Returns to Las Vegas Springs Preserve After Six Decades

Core Event: First Documented Sighting in Nearly 65 Years
A lone adult male Woodhouse’s Toad was captured on a trail-camera image in the Cienega wetland of the Springs Preserve. The photograph, taken in late June 2024, marks the first recorded appearance of the species on the 180-acre property since the original Las Vegas Springs dried up around 1962.
Background & Context: From Artesian Springs to Urban Wetland
The Springs Preserve sits atop the historic Las Vegas Springs, a network of artesian springs that sustained Indigenous peoples for millennia and later supplied water to early ranchers, the San Pedro, Los Angeles and Salt Lake Railroad, and the town that became Las Vegas in 1911. Intensive groundwater pumping in the mid-20th century caused the springs to run dry, eliminating the natural wetland ecosystem and its native amphibians, including the Las Vegas dace and the Vegas Valley leopard frog.
Key Figure: Senior Preserve Zoologist Katrina Smith
Katrina Smith, senior preserve zoologist, oversees the weekly review of wildlife-camera footage and routine amphibian surveys. Her team’s monitoring program enabled the unexpected detection of the toad, which otherwise would have gone unnoticed.
Data & Statistics: Species Range and Historical Shifts
Woodhouse’s Toad is common throughout Southern Nevada and the broader Southwest, favoring still-water habitats and feeding on spiders and insects. Its adaptability has allowed it to travel farther from permanent water than many other frogs, helping the species thrive despite regional water loss. In the Las Vegas Valley, Woodhouse’s Toads have displaced or hybridized with Arizona Toads, effectively replacing the latter since about 1976.
Why It Matters: Ecological Significance of an “Early Colonist”
Preserve officials describe the toad as a “possible early colonist,” suggesting the sighting could signal the re-establishment of amphibian life in a historically wet environment. Such a return may indicate improving habitat conditions or new migration pathways, both of which are valuable indicators for conservation planning in arid urban settings.
Official Statements & Responses
The Springs Preserve issued a statement calling the appearance “a big moment in local wildlife history.” Staff will continue routine surveillance with existing cameras and surveys but have no plans to expand monitoring efforts. The preserve emphasizes that the single male sighting does not confirm a breeding population.
Criticism & Opposition: Uncertainty Over Population Viability
Scientists caution that a solitary male does not prove a sustainable return. Without evidence of females or repeated calls, the toad could be an isolated visitor rather than the founder of a new population.
Conflicting Reports & Gaps
The toad’s route to the preserve remains unknown. Smith suggests possible travel through the Alta storm channel, which carries urban runoff into the Cienega, or overland movement across the Las Vegas Valley. No additional individuals have been recorded despite ongoing camera monitoring.
Verbatim Quotes
- “This appearance by our forlorn frog friend marks a big moment in local wildlife history,” — Springs Preserve officials
- “We wouldn’t have even known if it didn’t show up on my wildlife camera,” — Katrina Smith, Senior Preserve Zoologist
- “It’d be very rare for a visitor to see that toad on the property,” — Katrina Smith
- “It’s hard to say,” — Katrina Smith, when asked whether more Woodhouse’s toads could appear
What’s Next: Continued Observation
The preserve will maintain its existing wildlife-camera network and conduct routine amphibian surveys throughout the season, watching for additional calls or sightings that could clarify whether the toad represents the start of a returning population.
