Julia Bartens is a postdoctoral scholar at the University
of California and collaborates with the Urban Ecosystems and Social Dynamics Team of the USDA
Forest
Service’s Pacific Southwest Research Station in Davis, CA. She is mainly
involved with GIS and ecosystem service assessments. She received her PhD in
urban forestry and MS in urban horticulture, both from Virginia Tech. She has
published and reviewed scientific and technical publications, is an ISA
certified arborist, holds a graduate-level GIS certificate, and is a Tour des
Trees participant.
Dr. Greg McPherson is a Research Forester with the USDA Forest
Service’s Pacific Southwest Research Station located in Davis, CA. Greg grew up
under a canopy of American elm trees in Michigan. Despite attempts to save the
trees, all were lost to Dutch elm disease, and having felt the sting of that
loss he became a "green" accountant, developing new methods and tools
for quantifying the value of nature’s benefits from city trees. He works with a
team of 3 other scientists who measure and model effects of trees on energy
use, urban heat islands, air pollutant uptake, carbon sequestration, and
rainfall interception. Their research is helping justify investments in urban
forest planning and management. In 2000 Greg received the International
Society of Arboriculture’s (ISA) L.C. Chadwick Award for Research. Greg chairs
the ISA Tree Growth and Longevity Working Group and serves on the Science
Policy Advisory Committees of American Forests and the California Urban Forest
Council. He attended University of Michigan (BGS), Utah State University
(Masters in Landscape Architecture), and SUNY College of Environmental Science
and Forestry (Ph.D. Forestry).
Qingfu Xiao is a
scientist at the Department of Land, Air, and Water Resources, University of
California Davis and does joint research with the Urban Ecosystems and Social
Dynamics Program, PSW Research Station, USDA Forest Service. He studies urban
forest influences on urban hydrology, and measures and models urban
hydrological processes. He is also involved in mapping urban forests using GIS
and remote sensing.Qingfu received a
Bachelor's of Science degree in Computer Science from Huazhong University of
Science and Technology in the People's Republic of China and then received both
a Master's and a Ph.D. in Hydrologic Sciences from UC Davis. He enjoys bringing
Urban Forestry and Urban Hydrology together in his research.
Chunxia Wu received her MA degree in Agricultural
Engineering from Zhejiang University, China, and her PhD degree in Biosystems
Engineering from the University of Tennessee,Knoxville. She is a postdoctoral
researcher at the Department of Land Air and Water Resources at University of
California, Davis. Her research interests include RS/GIS spatial modeling, land
cover classification, and urban forestry studies.
