Ashfall, Amphibian Survivors



Many frogs and toads survived the ashfall because they were sheltered. They were underground, beneath logs, in muddy lake bottoms or in rock crevices.

Frogs and toads were more likely to survive because they breed often, and live in a variety of environments during their various life stages.

Some long-toed salamanders (Ambystoma macrodactylum) survived because they were below ground or under the bark of rotten logs.

Olympic salamander (Rhyacotriton olympicus) adults survived in rock crevices along stream sides. Young stream dwelling salamanders perished in ash-smothered stream bottoms.

Cascade frogs (Rana cascadae) survived the ashfall deposits. At that time of year, they were hibernating in the muddy bottoms of lakes.
