During the wet phase, the Mather Field Vernal Pools in the Illa
M. Collin Preserve host dozens of species of aquatic
invertebrates. Half of them have not even been named yet!
Watching and wondering about them draws us deeper into their
ancient, mysterious world. Bigger critters who eat them come to
the pools to dine: frogs, snakes, shore birds, wading birds, and
more. If you want to meet them, along with their famous pool
mates the Fairy Shrimp and Tadpole Shrimp, join us for a Critter
Walk!
