The Oregon spotted frog is now rare. Bullfrogs were brought into Washington and other western states to be farmed for culinary purposes. Bullfrogs, though, are probably not the only cause of declining populations of spotted frogs. The means for conservation of remaining populations of spotted frogs are not readily apparent. If nonindigenous species are the primary problem, some spotted frog populations remain vulnerable.
Scientists continue to discover bullfrogs in new localities in Washington and Oregon.
Habitat alterations from human activities also continue in most areas.
