CDFW Conservation Lecture Series
The CDFW Habitat Conservation Planning Branch is pleased to announce the Conservation Lecture Series. The lecture series is designed to deliver the most current scientific information about species that are of conservation concern.
Below is a list of lectures and speakers for CDFW’s Conservation Lecture Series. Lectures are open to anyone who is interested in participating. Participants may attend in-person or remotely via WebEx. Please be sure to register for each class. Lectures are recorded and posted for those unable to attend the day of the event. Scroll down to see recordings of past lectures.
California Red-Legged Frog – September 9, 1:00-3:00 pm. Presented by Jeff Alvarez
Biologist, Jeff Alvarez, has been working with sympatric populations of California tiger salamanders and California red-legged frogs for nearly 20 years. These apparently disparate species have many similarities and differences, yet aquatic and upland management techniques that support one species appear to support the other. Since the range of red-legged frogs and tiger salamanders overlap over a large area in California, species' management can impact or benefit both species. Jeff will present a lecture that includes discussion about the benefits of grazing, silt and vegetation removal, ground squirrel management, as well as habitat associations, rate of sympatry, inter-annual variability in observed breeding, and more, time permitting.

Townsend’s Big-Eared Bat – October 7, 1:00-3:00 pm. Presented by Dr. Dave Johnston
The Townsend’s big-eared bat is a candidate species under the California Endangered Species Act. Dr. Dave Johnston, an Associate Ecologist and Bat Biologist at H.T. Harvey & Associates has worked with bats since 1992.

Rearing Salmon in the Yolo Bypass – August 25, 2014. Presented by Carson Jeffres
Carson Jeffres, field and laboratory director for the UC Davis Center for Watershed Science, will discuss recent research on use of harvested rice fields as potential salmon nurseries. Frequently inundated large floodplains are functionally extinct in the Central Valley; many of the ecological benefits have been lost to riverine species. Since 2012 Jeffres has been studying whether flooded post-harvest rice fields can act as a surrogate for this lost habitat. Jeffres found that juvenile Chinook salmon on flooded rice fields grow at some of the fastest freshwater growth rates (.95mm/day) of juvenile salmon ever found in California. This talk will focus on what makes this surrogate floodplain productive and how inter-annual variation in weather dictates when and where conditions are suitable for the rearing juvenile Chinook salmon.

White Abalone – July 22, 2014. Presented by Dr. Kristin Aquilino
In 2001, white abalone became the first marine invertebrate to be federally listed as endangered, after intense over fishing in the 1970s severely depleted their population. Enhancement of the wild population through captive propagation was identified as the primary avenue for reversing the population's current trajectory toward extinction. In 2012, the Bodega Marine Laboratory celebrated the first instance of captive white abalone reproduction in nearly a decade, and small successes in captive reproduction have continued. Dr. Aquilino will discuss overcoming challenges in broodstock reproductive conditioning and increasing the survival of newly settled animals, which will help accelerate captive propagation and the recovery of wild white abalone populations.

Amargosa Vole – June 9, 2014. Presented by Dr. Janet Foley and Dr. Robert Klinger
The Amargosa vole is an endangered species with the possibility of extinction without immediate and on-going recovery actions. The presenters discuss population dynamics, habitat selection, occupancy patterns, and relationship of water to the distribution of the vole's habitat.

Desert Tortoise – May 22, 2014. Presented by Dr. Becky Jones
Rebecca Jones has been working with CDFW in the desert area since 1992 and is the Department lead for desert tortoise. In her presentation, Becky will be discussing desert tortoise biology, populations, threats, translocation and permitting.

Shasta Crayfish – April 29, 2014. Presented by Dr. Maria Ellis
Dr. Ellis has been studying the ecology of aquatic species in northeastern California since 1990. She wrote the Shasta crayfish draft recovery plan for CDFW and assisted USFWS in the preparation of the final recovery plan for the Shasta crayfish. Dr. Ellis helped to develop a Safe Harbor Agreement for Shasta Crayfish. In her presentation, Dr. Ellis discusses the ecology of the species, threats, and management activities that encourage recovery of the species and restoration of its habitat.

California Tiger Salamander – April 28, 2014. Presented by Dr. Chris Searcy
Dr. Searcy presents an overview of the natural history of this species. Dr. Searcy addresses seasonal activity and responses to weather patterns as well as migration distances and density distribution throughout the habitat. Dr. Searcy describes his most recent study results on hybridization with the invasive barred tiger salamander.

Alameda Striped Racer – April 24, 2014. Presented by Karen Swaim
Karen Swaim presents current scientific information on Alameda striped racer. Her lecture focuses on the life history of the species, including biology, habitat use, and behavior. Karen addresses conservation and management issues.
Cactus Wren – April 17, 2014. Presented by Dr. Kristine Preston
The coastal cactus wren has declined precipitously in southern California over the last twenty years as a result of habitat loss and fragmentation due to urbanization and catastrophic wildfires. Dr. Preston discusses results of a regional collaborative partnership that has worked to address key questions critical to developing effective management actions to halt the wren’s decline.

Sierra Nevada and Sacramento Valley Red Foxes – April 11, 2014. Presented by Dr. Ben Sacks
Dr. Sacks discusses research on Sierra Nevada red fox and the Sacramento Valley red fox. Historically, Sierra Nevada red fox were present throughout the subalpine zone of the Sierra Nevada range in California but over the last century, their abundance and distribution have declined dramatically. The Sacramento Valley red fox was recently shown to be a second native subspecies confined to the northern Central Valley. Dr. Sacks presents findings on biogeography, ecology, and conservation issues in the context of previous and ongoing research.

Yellow Starthistle – March 17, 2014. Presented by Dr. Joseph DiTomaso
Dr. DiTomaso discusses the life history of yellow starthistle, an invasive weed, including the biology of the plant, why it is a problem, and how it affects the landscape. Dr. DiTomaso discusses management strategies including herbicides, burning, and hand removal and how these strategies can be best applied to minimize non-target species damage. Dr. DiTomaso includes an overview of Integrated Pest Management (IPM) strategies that can be used to address yellow starthistle.
