Chapter Board Members


Kiersten Abarca

Kiersten obtained a B.S. in Biology from California Lutheran University in 2014. She then continued into the zoological field as a rehabilitation volunteer and Docent at the California Living Museum (CALM). In 2016 she was hired as an animal keeper for CALM primarily working with the collection raptors and ambassador animals, while continuing to participate in their rehabilitation and outreach centers. In 2018 Kiersten accepted a position at the Fresno Chaffee Zoo, continuing her work with birds as a primary bird keeper. During her time as a zookeeper, she was introduced to a variety of wildlife organizations, each having their role to play in conservation efforts. This led to an increased passion for learning more about how she could personally contribute to wildlife conservation. Currently Kiersten works as a biological consultant with McCormick Biological, Inc., and is pursuing an education in wildlife management.


Kacy Twist

Kacy is a Bakersfield native who graduated from CSUB where she obtained a BS in Biology. She started her career in biology as a consultant, first at QuadKnopf and then McCormick Biological, Inc., working almost exclusively on developments and energy projects such as wind, solar, co-generation plants, and oil and gas. After 13 years at McCormick Biological, Inc., she transitioned into working at Chevron as a Natural Resource Advisor in the Health, Environmental, and Safety department. In her role at Chevron, Kacy advises on threatened and endangered species compliance, conservation and natural resource protections, CESA/ESA permitting, spill response, emerging legs and regs, and everything else that goes along with being the only resident biologist in Chevron’s San Joaquin Valley Business Unit. In addition, she has assisted the Endangered Species Recovery Program staff to gain access to Chevron lands in support of San Joaquin kit fox urban sarcoptic mange camera surveys and their San Joaquin kit fox Coalinga study. She provides access for researchers to conduct multi-year surveys for Temblor legless lizard throughout the species range, and provides Tejon Indian Tribe staff access to Lokern lands in support of recent inventory surveys. Her recent focus has been coordinating eDNA work for the Temblor legless lizard through collaboration with Chevron scientists, researchers, and university and private genome labs. This will be Kacy’s second time serving as president for the Chapter!

Past President

Rainey Davis

Rainey Davis’s passion for wildlife stems from a very young age, where her common hobbies were picking up lizards, frogs, and even snails to bring home as pets. She has taken that passion for wildlife and turned it into a career as a Biology Consultant with McCormick Biological, Inc. She earned her B.S. in Biology in 2018 from CSU, Bakersfield. She has participated in volunteering opportunities with the Endangered Species Recovery Program since 2011 and volunteered with the California Living Museum from 2013-2016. Rainey has been an active member of the San Joaquin Valley Chapter for the last few years and has assisted with the Natural Communities Conference annual photo competition for the past couple years.


Julie Vance

At the California Department of Fish and Wildlife, Julie manages regulatory programs for activities proposed in CDFW’s Central Region, which includes the San Joaquin Valley, as well as in the Kern County portion of the Mohave Desert and San Benito, Monterey, and San Luis Obispo Counties. She has been at CDFW for the past 10 years, and prior to that time she worked for the Department of Water Resources (DWR) out of the Fresno Office. At DWR she spent much of her time conducting surveys for rare southern San Joaquin Valley species, such as blunt-nosed leopard lizard, kangaroo rats, San Joaquin kit fox, burrowing owl, and Swainson’s hawk. She has lived in the San Joaquin Valley (Fresno) since elementary school. She attended Fresno City College and CSU Fresno, where she obtained a BS in Ecology (1996) and an MS in Biology (2000). Her thesis was entitled “Instream Movements of the California Newt in an Intermittent Central California Foothill Stream.” Since 2001, she has continued to study PIT-tagged newts at the McKenzie Preserve in her free time. She also spends personal time gardening, cooking, hiking, camping, beach combing, and playing with her two young boys.


Ryan Lopez

Ryan has been involved with The Wildlife Society for many years now, and is excited to help the San Joaquin Valley Chapter use its talent and resources for the benefit of the membership and our local environment. His involvement with local wildlife issues began in High School, continued as a Fresno State Presidents Scholar while receiving his bachelors and masters in Biology/Ecology, and continues today through his profession. During college, he worked in the Fresno State Forest Ecology lab on projects in the Sequoia National Park, the Sierra National Forest, and the foothills of Kern County. He worked with the NRCS mapping invasive vegetation on the Kaweah River, with the San Joaquin River Parkway as a canoe guide, completed over 600 hours of college level instruction for Fresno State and Fresno City College in science courses, and was an EPA Star-GRO Fellow from 2004-2006. After college he began work as a conservation biologist specializing in special status species surveys, mitigation development, entitlement, land acquisition, conservation budgeting and planning, and land management on multiple projects throughout California, as well as Oregon and Georgia. Ryan has been integrally involved with the permanent protection of ~40,000 acres of habitat for threatened and endangered species and habitat types. Ryan has experience with special status plants and animals including desert tortoise, vernal pool species, giant kangaroo rat, San Joaquin kit fox, salt marsh harvest mouse, and delta smelt, among others. Ryan currently works at the Natural Resources Group as a Senior Conservation Scientist.
