A picture of Rebecca L. Cull, Principal

Founding principal and ecologist Rebecca Cull follows tracks along the Sacramento River at the Mouth of Cottonwood Creek Wildlife Area.

Ms. Rebecca Cull is a founding principal and current president of Sustain Environmental. During her 30-year career, Rebecca has worked for small private firms, multimillion-dollar companies, universities, and state agencies in both business management and ecological studies. Her attention to detail, awareness of systems, and insight into animal behavior (humans included) make her an excellent project manager.

Rebecca’s specialties are designing, supervising and conducting ecological studies and developing adaptive management plans for monitoring and improving natural systems. Her reports are highly regarded by resource agency personnel and her astute assessments help reduce the need for prolonged environmental reviews under the California Environmental Quality Act (CEQA) and National Environmental Policy Act (NEPA). She has completed numerous projects requiring technical expertise in Endangered Species Act (ESA) Section 7 consults, Caltrans and Federal Highway Administration requirements and standards, wetlands permitting (US Army Corps of Engineers and California Department of Fish and Wildlife), and mitigation design and implementation. Well versed in federal and state survey protocols for listed and special-status wildlife species in the western United States, Rebecca has extensive field experience with raptors, terrestrial birds, small mammals, reptiles, amphibians, and vernal pool invertebrates.

Ms. Cull has managed and conducted environmental studies covering hundreds of miles for energy transmission and transportation projects that have crossed state lines as well as federal and private properties. She is particularly adept at tailoring work plans to meet the requirements of multiple jurisdictions. Years of supervising and working with field crews in remote areas, often under adverse conditions, have honed her ability to elicit cooperation and understanding from project personnel while meeting both permitting requirements and client needs.

A noted specialist in burrowing owls and Swainson’s hawks, Rebecca has conducted surveys, assisted with banding efforts, and participated in long-term monitoring of both species throughout northeastern and central California. An active member of the Burrowing Owl Consortium since 1992, Ms. Cull was a key participant in the development of the Burrowing Owl Survey Protocol and Mitigation Guidelines, informally adopted by the California Department of Fish and Game in 1995. She is the primary author of the “Status of Burrowing Owls in Northeastern California,” published in 2007.

Rebecca’s interest in sustainable living was piqued by her early childhood experiences and later travel to remote locations. An experienced coastal and blue water sailor, she was one of a four-person crew on the Unlikely VII during an eight-week oceanic passage from India to Israel that included ports of call in Oman, South Yemen and Sudan. More recent adventures took her on several trips to Kenya, and to French Polynesia. Wherever her journeys take her, she always brings a keen interest in the natural world and sensitivity to local cultures.

A picture of Kristina VanBlaricom

Field biologist and wildlife specialist Kristina VanBlaricom shows her grit counting black abalone on San Nicolas Island as part of a longitudinal study on population trends.

Ms. Kristina VanBlaricom began her lifework studying and handling wildlife in 1977 as part of a nascent effort by Monterey County SPCA to establish a Wildlife Rescue and Rehabilitation Center. The Wildlife Center quickly grew to become the only full-service wildlife rescue in Monterey County, taking in 2,000 animals a year as part of a working relationship with the then California Department of Fish and Game. Kristina worked directly under the Wildlife Center’s permitted biologist, developing highly technical skills and specialized knowledge in wildlife observation, behavior and handling. During her time there, she assisted in the capture, restraint, transport, and release of a wide array of wildlife, including mountain lions, sea otters, bobcats, coyotes, raccoons, opossums, weasels, rodents, eagles, hawks, owls, seabirds, and songbirds.

In 1984, as one of the few individuals with hands-on expertise in the care and handling of sea otters, Kristina was hired by the newly opened Monterey Bay Aquarium. She later became the Aquarium’s aviculturist and curator for its sandy shores exhibit and marine bird exhibit. The US Fish and Wildlife Service also retained Kristina’s services to assist with the translocation and reintroduction of sea otters to waters south of Monterey Bay. During this effort, Ms. VanBlaricom was recruited to assist in an ongoing USFWS/USGS longitudinal research study on endangered black abalone on San Nicolas Island. For the past 25 years, she has assisted with biannual abalone surveys, maintaining her naval security clearance for ecological studies on this westernmost Channel Island.

Ms. VanBlaricom is currently assisting Sustain with mortality counts at a wind farm in Rio Vista. Kristina’s broad experience with natural life cycles and predation, her familiarity with collateral damage to wildlife, and her respect for the role of science make her an invaluable addition to any project that requires both detachment and compassion.
