Dr. Spencer is a wildlife conservation biologist with over 35 years of professional experience in biological research and conservation planning. He specializes in the practical application of science to resources management, design and management of nature reserves, and recovery of endangered species. He has conducted numerous studies on rare and sensitive mammals, with particular focus on forest carnivores (martens and fishers) and endangered rodents (Pacific pocket mouse and Stephens’ kangaroo rat). Dr. Spencer has prepared habitat conservation plans (HCPs), habitat management plans (HMPs), and natural community conservation plans (NCCPs) for numerous sensitive species in California, including the first NCCP plan ever permitted (Poway Subarea NCCP/HCP). He also uses ecological expertise to guide large-scale efforts to conserve ecological connectivity and wildlife movement (such as the South Coast Missing Linkages Project and the California Essential Habitat Connectivity Project) as well as to restore and sustain resilient forest conditions in the face of changing climate and wildfire regimes (such as the Sierra Nevada Forest Resilience Initiative). Because he combines ecological research with real-world conservation planning experience, Dr. Spencer is often asked to lead science advisory processes for regional conservation and recovery plans, such as the California Desert Renewable Energy Conservation Plan and the Sacramento-San Joaquin Bay Delta Conservation Plan. He currently leads large teams working to conserve the endangered distinct population of fishers in the Sierra Nevada and the endangered Stephens’ kangaroo rat in southern California.
Heather joined CBI in August 2003. She is a landscape ecologist/GIS specialist whose work has focused on predicting effects of land management and landscape change on vertebrates with spatially explicit habitat, population, and connectivity models. She has over 10 years of experience in applied ecological GIS analysis and modeling. Heather graduated from Middlebury College with a B.A. in environmental studies, and received master’s degrees in biology from William Paterson University and geography from Oregon State University. Her recent work at CBI has focused on the conservation of fishers, martens, and other carnivores in the Sierra Nevada.
Alexandra Syphard is a research ecologist who investigates landscape change that results from the interplay between human and natural disturbances, especially wildfire, urban development, and climate change. She uses a variety of spatial analytical and modeling methods to investigate how change has occurred in the past, how it is likely to occur in the future, and what types of ecological impacts are likely to result. She also envisions how alternate management scenarios may differentially impact the biological and social integrity of different landscapes. Alexandra works on issues related to vegetation dynamics and wildfire in Mediterranean ecosystems; fire science and ecology; effects of multiple threats to native vegetation communities; biogeography and species distribution modeling; land use / land cover change; and the influence of humans on fire regimes.
Before joining CBI in 2007, Alexandra earned her PhD in Geography from San Diego State University and the University of California, Santa Barbara in 2005. Alexandra also received a BA in English from the University of Mary Washington, a Masters of Public Health at the Medical College of Virginia, and a Masters in Environmental Studies at Virginia Commonwealth University. She also completed a postdoctoral research fellowship in the Department of Forest Ecology & Management at the University of Wisconsin, Madison and a postdoctoral fellowship in the Department of Biology at San Diego State.
In her free time, Alexandra enjoys playing guitar, riding her Vespa scooter, running or practicing yoga, traveling to different countries, and drinking a good cup of coffee with her family and friends.
