The Nature of Phenology 4/20/24: Vernal Pools

Producers: Hazel Stark & Joe Horn
Host: Hazel Stark

They form in depressions in the forest floor and are large enough to last for a few months, but small enough that they tend to dry out by mid-summer. As a result, vernal pools have no fish in them. This lack of a key predator population makes them a perfect place for amphibians to breed.
