Portia Halbert is an Environmental Scientist with the Santa Cruz District of California State Parks. For 16 years she has been part of a resource management team who works to manage parkland and restore habitat in the 70,000 acres of Parks in Santa Cruz and San Mateo counties. Her experience is based on a wide variety of things she has had the opportunity to do such as restoration using heavy equipment for earthmoving, planting and maintaining large areas with native plants, refining the work on invasive exotic plants and incorporating early detection and rapid response, and working with sensitive species such as the California red-legged frog and San Francisco garter snake. As a last and personal favorite, she is also a member the statewide burn crew, helping to reintroduce fire to the landscape; through this work she has discovered that everyone is a closeted pyromaniac. In her consulting business she conducts inland surveys for the marbled murrelet, and eradicates non-native plant species. She is a member of the California Invasive Plant Council.

Master of Science, Ecology, Rutgers University
Certified Wildlife Biologist, TWS (formerly, see note below about TWS)

Steve is the owner of Steven Singer Environmental and Ecological Services, a local environmental consulting business that specializes in forest biology, old-growth redwood ecosystems, and inland habitat management for the Marbled Murrelet, an endangered seabird. He is the co-editor of the Marbled Murrelet Landscape Management Plan for the Santa Cruz Mountains (Zone 6). His pioneering research on the nesting ecology of the Marbled Murrelet has been partially recounted in the book, Rare Bird, by Maria Ruth. He continues to monitor murrelet numbers locally and is a member of the Marbled Murrelet Technical Committee of the Pacific Seabird Group. Formerly, he also consulted in wildland soil conservation work, which included road removal, trail design, repair of logged-over lands, channel stabilization, and gully control. Steve was the first person to formulate successful treatment methods for the abundant gullies found on sodic subsoils in coastal San Mateo County. For many years he was an adjunct faculty member at Cabrillo College where he taught a Soil Conservation class.  Steve is a Research Associate for the Santa Cruz City Museum of Natural History, and a member of the Cooper Ornithological Society, the Pacific Seabird Group, and the California Native Plant Society. He is a former member of the Wildlife Society but discontinued his membership when that organization betrayed its membership and its own stated goals by supporting the wildlife policies of the Trump administration.

Jerry Smith is a retired former Associate Professor of Biological Sciences at San Jose State University, where he taught Aquatic Ecology, Fisheries Management, and Conservation Biology. Since 1972 he has conducted research on the distribution and ecology of freshwater fishes in the central coast of California. Since 1984 most of his fish studies have been concerned with stream and estuarine ecology of steelhead, coho salmon, and tidewater goby. He served on the federal recovery team for the threatened delta smelt (San Francisco Bay Delta – native fishes), the state restoration team for the endangered coho salmon, and on the federal recovery team for the threatened coastal Chinook and steelhead, and endangered coho salmon. Since 1995 he and his students have conducted detailed studies of California red-legged frogs and western pond turtles at Waddell Creek in Santa Cruz County and Coyote Creek in Santa Clara County. Dr. Smith has been the major advisor for 21 master's degree theses on: stream and estuarine invertebrate ecology; steelhead, red-legged frog, foothill yellow-legged frog, and western pond turtle ecology; and steelhead, tidewater goby, and spotted owl genetics.
