President-elect: Kim Klementowski

Kim Klementowski is the President-elect for the Southern California Chapter.  She is the Orange/Riverside Counties Regional Preserve Manager with the Center for Natural Lands Management, where she manages preserves set aside for threatened and endangered species.  Her work focuses on all aspects of conservation lands management, including weed control and habitat enhancement, surveys and population trends, and long-term vegetation monitoring, with emphasis on coastal California gnatcatcher, vernal pools and fairy shrimp, and burrowing owl.  After earning her master’s degree in Geography from CSU, Chico, Kim worked in various positions in the Lassen foothills, the Sonoran Desert, and San Clemente Island, before landing back in SoCal where she grew up.  When not working, she can be found rock climbing in the desert, snowboarding in the Sierras, or tearing apart her house for another DIY project.  She lives in Homeland with her partner Will and their “kids”, Jojin and Dalea.


Past-President: Wendy Loeffler

She obtained both a B.A. and M.A in Biology from California State University, Fullerton, where she studied the diets of locally nesting seabirds. Upon completion of her advanced degree, Ms. Loeffler entered the environmental consulting world. She worked first and briefly in Orange County, and then settled with RECON in San Diego over 20 years ago. She holds a recovery permit to study and survey for the coastal California gnatcatcher, fairy shrimp, and the Quino checkerspot butterfly. She has trained and conducted surveys for desert tortoise and flat-tailed horned lizard, as well as focused surveys for rare plants, sensitive riparian bird species, burrowing owls and other sensitive raptors, and assisted with mammal trapping, insect inventories, and pitfall trapping.

Ms. Loeffler has been involved with the local chapter for over 7 years, starting out as the membership chair and subsequently being appointed as the Interim President when the previous leadership stepped down. She looks forward to growing the local chapter and seeing the program expand to provide greater benefit to southern California wildlife biologists. Ms. Loeffler resides in La Mesa, California with her son Garrett.

She also studied geographic information systems at San Diego Mesa College. Her experience includes field surveys, biological monitoring, and technical report preparation for terrestrial biological resources in southern California. Her favorite part of her job is assisting with special-status species surveys for coastal California gnatcatcher, burrowing owl, least Bell’s vireo, light-footed Ridgway’s rail, desert tortoise, Quino checkerspot butterfly, and small mammals such as Mohave ground squirrel, San Bernardino kangaroo rat, giant kangaroo rat, Los Angeles pocket mouse, and Palm Springs pocket mouse. She currently also serves as the media communications committee chair sharing Chapter happenings and news on Facebook, LinkedIn, and Instagram.

Chapter Representative to TWS Western Section: Colleen Wisinski

Colleen Wisinski works at San Diego Zoo Wildlife Alliance as a Conservation Program Manager in Recovery Ecology, where she leads the burrowing owl recovery program. Colleen’s main research focus is the ecology and conservation of burrowing owls in Southern California, particularly of the breeding population of burrowing owls in San Diego County. She is responsible for overseeing the field team, managing and analyzing data, and working with partners, including conservation planning and making recommendations about management of the species to local land and wildlife managers. Using direct observations, remote cameras, GPS transmitters, and color banding, she and the team are learning about survival, reproduction, and movement of the owls in the region. The team also uses translocation and conservation breeding to help bolster the burrowing owl population. Colleen earned her bachelor’s degree in Biology and Spanish from the University of Wisconsin – Green Bay, and her master’s degree in Fish and Wildlife Management from Montana State University in Bozeman, where she examined survival and habitat use of greater sage-grouse in southwestern Montana. Colleen has also worked as a wildlife rehabilitator where she trained several raptors for educational purposes, and as a whooping crane tracker where she used radio and satellite telemetry to monitor a reintroduced population of cranes. She has been a member of The Wildlife Society since college and has served the Southern California Chapter in multiple capacities since 2015. Colleen loves that she gets to work outdoors and be creative to figure out how to answer research questions in the field. Her love for animals and nature grew from her time spent outdoors in the North Woods of Wisconsin.
