It is a medium-sized aquatic frog endemic to the Pacific Northwest and historically well distributed in the Puget Trough/Willamette Valley province and the Cascade Mountains of south-central Washington and Oregon.

[4] As tadpoles, their back and tail musculature are brown and lack dark spotting, while the belly is a creamy white or aluminum color.

[4] The Oregon spotted frog's reproduction is strictly aquatic and their late winter breeding season is brief, less than four weeks in duration.

Males call quietly during the day or night from the vicinity of traditional oviposition sites, places where females lay their eggs in communal piles.

Though egg masses are occasionally laid singly, communal oviposition sites usually comprise the majority of the annual reproductive output.

[4] Once fertilized, the eggs of the Oregon spotted frog begin to enter the larval stage of their development very quickly.

Its decline has also been linked to areas inhabited by the introduced bullfrog and related to loss and degradation of breeding habitat such as may result from dam construction, alteration of drainage patterns, dewatering due to urban and agricultural use of water, excessive livestock grazing, and other human activities that reduce or eliminate lentic shallow water.

[1] Several organizations associated with the NW Zoo and Aquarium Alliance[13] are working on recovery projects for the Oregon spotted frog.

[18] School groups are also involved in enhancing habitat for the Oregon spotted frog by managing canarygrass and bullfrogs.

[19] On April 15th, 2024, Canada Post released a stamp with an Oregon spotted frog to attract public attention to these amphibians.
