The ExperTalk Series is a great way for members of the community to learn more about topics related to Bolsa Chica, such as local plants and wildlife, restoration practices, nutrient cycling within wetlands, and Native American history! Our ExperTalk series also provide presentations on current day issues relating to environmental conservation and other relative ecology topics such as drought-tolerant landscaping and local biodiversity of zooplankton.

Upcoming ExperTalk Events:

The Geologic History of Southern California by Eric Cathcart, M.S.

Description: California is renowned throughout the world for our biological diversity, but the geologic history of the region is just as fascinating as our plant and animal life. The geology of California is highly complex, with numerous mountain ranges, substantial and historically intense tectonic activity, and rich natural resources that have made the state a mining hotspot. But what exactly happened all those millions of years ago that shaped California as it is today? To find out, join the Conservancy and Eric Cathcart as he describes the very unique conditions that created the geologic wonders of Southern California.

Speaker Biography: Eric Cathcart, M.S. is a professor of environmental and ocean sciences at the University of San Diego. Cathcart earned his Masters of Science from USD in 1996, and is also a licensed California Professional Geologist, as well as an environmental consultant. In terms of scholarly work, Cathcart has published multiple reports and articles for government regulatory agencies and professional journals, with the majority of his work focused on isotope geochemistry, micropaleontology, sedimentology, hydrology, and metal contamination, among others. Currently, Cathcart is researching the geogenic concentrations of metals in formations throughout San Diego County, which will be utilized by local government, researchers and regulatory agencies to establish background and health risk-based thresholds for remediation of contaminated properties. Cathcart is also actively involved with community science education and outreach, and is involved with organizations like SeaCamp, Ocean Discovery Institute, and Tecolote Canyon Natural Park and Nature Center.

Duration: approx. 1 hour Suggested Donation: $5.00 per participant*

Expert Talk Series “Penquin Etiquette (and other things I learned in Antarctica” with Chris Epting | April 22, 2018

Synopsis: Expanding our reach to bring you topics on ocean connectivity, award-winning author Chris Epting returned on Earth Day 2018 to enthrall you with stories about an unforgettable trip he and his then teenage daughter took to a little-known place called Snow Hill Island in Antarctica, where he observed and studied Emperor Penguins, a unique and challenging adventure. In the talk, Epting explores ecologic connections between creatures of the deep icy southern hemisphere and our wetland ecosystems, and why it is important to protect and preserve our natural habitats.


Expert Talk Series “The Camping Trip that Changed America” - Teddy Roosevelt and John Muir in Yosemite” with Chris Epting | March 15, 2018

Synopsis: In 1903, President Theodore Roosevelt embarked on his first visit to California. Before leaving, he reached out to naturalist John Muir with a special favor: to act as the president’s tour guide in Yosemite. That became what many refer to as “The Camping Trip that Changed America.” Join author Chris Epting for a presentation on how that fateful three-day trip helped to shape the destiny of Yosemite and the National Park system.


ExperTalk Series "Hidden Wetlands History: The Bolsa Chica Gun Club" with Chris Epting | January 24, 2018

Synopsis: Established at the turn of the 20th century, the Bolsa Chica Gun Club was the most elaborate and exclusive of all Orange County hunting clubs. Both mythical and controversial, it even played a part in World War II before being left to disintegrate for decades after. What was is it like there? What really went on there? What effects did it have on the environment? Author/journalist Chris Epting will tell the story using little-seen images, documents and even a rare film clip, after leading a walking tour to the site for further discussion.


ExperTalk Series “Sharks, the Myth of the Monster" with Jim Serpa | July 27, 2017

Synopsis: The shark, the myth, the legend. Sharks have existed for millions of years and are generally misunderstood and demonized. For many years they have been dwindling in numbers; some have been pushed to near extinction, in part due to human hostility, illegal fishing and hunting for fins and teeth. People think sharks are vicious creatures, overlooking the fact that we have invaded their waters. Researchers are utilizing tagging and satellite technology to better understand these amazing, yet misconceived ocean animals to piece together their unknown behavior and migratory patterns. Many have been spotted off California’s coast, shutting down beaches and raising public concerns. To learn more about these animals, join the Conservancy and Mr. Jim Serpa as he sheds the light on these widely misunderstood creatures.
