The Northern Red-legged Frog lives in the Pacific Northwest. They breed from January to March depending on how far north they are located. The farther north they are, the later they breed. Egg masses from the frogs number between 300 and 5000 eggs. The eggs hatch in about a week into tadpoles. The tadpoles take 3 to 7 months to fully undergo metamorphosis. Some of the tadpoles take until the next spring to turn into frogs. Adult frogs can live up to 10 years.

The International Union for the Conservation of Nature (IUCN) Red List assesses the Northern Red-legged Frog as Least Concern with Extinction. The frog has a good sized range and a large population.
