Rio Grande Leopard Frog
Lithobates berlandieri · also called Rio Grande leopard frogs
Along an irrigation canal cutting through otherwise dry Texas borderland, a Rio Grande leopard frog thrives in water most native wetland species would never encounter, an adaptability to artificial habitat that has kept the species common across a genuinely arid range.
Overview
The Rio Grande leopard frog, Lithobates berlandieri, is a warm-tolerant frog native to wetland and desert-edge habitat across the Rio Grande Valley of Texas and adjacent northern Mexico. Its comfort with artificial water sources and unusually high tolerance for arid conditions make it one of the more adaptable leopard frogs in the southwestern borderlands.
A frog that made peace with irrigation
Where many amphibians struggle in agricultural landscapes, the Rio Grande leopard frog has instead embraced canals and stock tanks as genuine substitutes for natural wetlands, a flexibility that has kept the species thriving across dry country most other frogs would avoid entirely.
Status
Least Concern — widespread and common across suitable wetland and artificial water habitat throughout the Rio Grande Valley and adjacent borderlands.
Rio Grande Leopard Frog: common questions
How does the Rio Grande leopard frog survive in such dry country?
A Rio Grande leopard frog tolerates warmer and more arid conditions than several other leopard frog species, and it readily uses artificial water sources such as irrigation canals, stock tanks, and drainage ditches, habitats that have helped the species remain common even across otherwise dry borderland landscapes.
Is the Rio Grande leopard frog easy to tell apart from other leopard frogs?
Not always — the Rio Grande leopard frog belongs to a broader cluster of similar-looking North American leopard frog species, and visual identification alone can be unreliable within this group, making range and call often more useful than appearance for confirming which species is present.
Does the Rio Grande leopard frog need permanent water to breed?
No, a Rio Grande leopard frog breeds in both permanent and temporary water bodies, an adaptability well suited to the unpredictable rainfall patterns typical of its arid borderland range.
Where does the Rio Grande leopard frog live?
The Rio Grande leopard frog is native to wetland and desert-edge habitat across the Rio Grande Valley of Texas and adjacent northern Mexico, readily using both natural and artificial water sources.
