Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Introduced predators such as bullfrogs could destroy this species. Damage to habitat caused by livestock is also a great threat. Burning the marshes surrounding the springs or changing the flow of the water channels would destroy the toad’s only habitat.
