The Northern Pacific Tree Frog (Pseudacris Regilla) is a common sight to many in Humboldt County. Despite their name, these small frogs actually prefer to live in moist, low vegetation near freshwater sources. You can find them all around the Arcata Marsh during the wet season. In drier areas, they will hibernate in a damp area until their preferred habitat returns.
Most Northern Pacific Tree Frogs are green with a black stripe across their eye, but some are a mottled brown color. Their distinctive “rrribbit” call is a one of the most common frog calls around here. So if you hear frogs croaking away at night, it’s probably these guys!
Fun Fact: Hibernating Pacific Tree Frogs were some of the few vertebrates that survived the explosion of Mt. St. Helens.
