During the hot, dry summer months, vernal pools lie brown and barren among the grasslands. Birds, mammals and insects come to the pools to feed on the seeds and bulbs of vernal pool plants. While they are there, other species feed on them.

The sun-baked bottoms of the vernal pools hold the eggs, cysts and seeds that will give life to the next generation. The winter rain awakens them, restarting the cycle each year.

Meet Christopher Rogers, Invertebrate Zoologist

Christopher Rogers is an Invertebrate Zoologist, which is a scientist who studies animals without backbones. Specifically, he studies the invertebrates that live in vernal pools. He has travelled all over the world looking for new species in new places.

Patient, little bees

Solitary Bees generally only collect pollen and nectar from a single species of plant (or from a few closely-related plants). Researchers have discovered that vernal pool Solitary Bees can hibernate underground for up to four years, waiting for the 2-3 weeks when their host plant is in bloom.
