Ph.D. Sr. Marine Biologist and Associate

Dr. Kitting, earning his Biological Sciences B.S. at University of California and Ph.D. at Stanford University, has authored >35 widely cited, diverse ecological publications in reviewed scientific journals, plus numerous other reports, manuals, and published photographic illustrations.

His students have authored many additional publications. He also has been principal investigator on well over 20 major research grants (plus his renewals) at Cal State University East Bay, and completed other award-winning projects at NOAA, NASA and other agencies. He also is a founding Board Member of San Francisco Bay Wildlife Society, Charter member of Ward Creek Alliance, and recently has been a member of three other watershed organizations, including McNabney Marsh Advisory Committee, successfully managing a restored wastewater marsh in Martinez. He has long maintained active professional membership in Society of Wetlands Scientists, Coastal and Estuarine Research Federation (CERF), and American Fisheries Society (AFS) and their Chapters, and in over four related international ecological societies, where he presents new talks and posters several times each year at local and international conferences. He recently has served as president (elected for multiple terms) in two major scientific societies, including San Francisco Bay Wildlife Society, supporting US Fish and Wildlife Service Refuges along the West Coast. He also is a reviewer for major journals etc., and serves on two editorial boards of scientific journals. He also edited and wrote a chapter for the book Migration: Mechanisms and Adaptive Significance. Recently he was acknowledged for assistance to the National Marine Estuary Program through Louisiana State University, and locally.

Michael Bumgardner

Partnering Principal and Sr. Wildlife Biologist

Mr. Bumgardner partnering Principal of Bumgardner Biological Consulting, has a Bachelor of Science degree in Zoology from the University of California at Davis. He spent several years in the Joint Doctoral Program in Ecology at the University of California at Davis and San Diego State University.

Mr. Bumgardner has more than 24 years of experience in conducting biological assessments, studies, and inventories, and developing mitigation, restoration, conservation plans and strategies, and constraints analysis. His cliental includes State and Federal, natural gas and oil industry, reclamation districts, ski industry, mining industry, transportation agencies, Union Pacific Railroad, water, wastewater and power utilities, and building industry. He currently holds federal scientific take permits for California gnatcatcher, southwestern willow flycatcher, and California Ridgeway’s rail (permit number TE-785564-7), a federal scientific take permit for the California Tiger Salamander (permit number TE-785564-6), a California Department of Fish and Game scientific collector’s permit (No. 801214-01) and letter of agreement to conduct surveys for yellow-billed cuckoo, willow flycatcher, California gnatcatcher, California black rail, and California clapper rail.

Christopher Gray

Staff Terrestrial Ecologist

Mr. Gray obtained his BS in Biological Sciences from California State University Sacramento with emphasis in ecology and conservation. He has experience conducting protocol level surveys for special status species and is capable of identifying a range of organisms; birds, amphibians and reptiles, insects, and fish.

Mr. Gray has assisted Dr. Graening of CSU Sacramento for several years with cave research throughout California performing biological inventories. He has also worked for the Catalina Environmental Leadership Program on Catalina Island. During his time there he worked with college students, educating groups on terrestrial and aquatic ecology while stressing the importance of sustainability. Educating such diverse groups allowed Chris the opportunity to gain experience breaking down complex concepts in order to explain them more easily and in different ways to younger groups. His experience with GIS/GPS mapping allows him to assist clients in multiple fields. He has experience performing biological resource assessments for CEQA documentation and status species clearance surveys. QSP trained, Mr. Gray also provides SWPPP inspections.
