Fewer than 10 populations of Oregon spotted frogs remain in the wild across North America, with the largest concentration found in the Williamson River drainage of south-central Oregon.
- 06
Oregon spotted frogs require permanent water bodies with minimal disturbance, making them extremely vulnerable to habitat loss from wetland drainage and urban development across their remaining range.
- 05
Male Oregon spotted frogs produce distinctive clicking and chirping vocalizations during breeding season to attract females to suitable breeding sites.
- 04
A single Oregon spotted frog can live up to 9 years in captivity, making longevity studies crucial for conservation breeding programs.
- 03
Bright red coloring on the belly and underside of Oregon spotted frogs serves as a warning to predators of their toxic skin secretions.
- 02
Aquatic vegetation in breeding ponds allows Oregon spotted frogs to lay up to 1,500 eggs per female during their spring spawning season.
