Distribution and Ecology of Vernal Pools

December 14, 2023 @ 7:30 pm - 8:30 pm

Kaleidoscopes were a favorite holiday gift for children many years ago. They displayed a quickly and constantly changing series of brilliantly colored patterns. The metaphor works for California’s vernal pool landscapes.

Carol Witham will help us to explore the short-lived, weird-looking, fascinating fauna that evolved millions of years ago, and dazzling swaths of tens of thousands of tiny flowers that change from week to week through a two- to- three month “season”.

This tour of California vernal pools will answer questions such as “what makes a vernal pool” and “why are they found almost nowhere but California” plus explore vernal pools from throughout the state.

Carol Witham is a self-taught vernal pool ecologist and has been studying that ecosystem for over three decades. She is a private consultant specializing rare plants and animals of vernal pools plus their management. Carol is author of Field Guide to the Vernal Pools of Mather Field, Sacramento County and co-editor of Jepson Prairie Preserve Handbook, 3rd Edition. She is also very active in vernal pool conservation advocacy and education.

Carol is currently the treasurer for the Sacramento Valley Chapter and a member of the state board of directors of CNPS. In the past she has served in several leadership roles within the statewide organization including president, vice-president and treasurer.
