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 Howell, 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 scientists to 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 L.C. Chadwick Award for Research. Greg was a co-founder and Chair of the Tree Growth and Longevity Working Group and serves on the California Urban Forest Advisory 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).
