Kathleen Wolf is Research Social Scientist in the College of the Environment at the University of Washington. Wolf’s studies are based on the fundamental principles of environmental psychology; her professional mission is to discover, understand and communicate human behavior and benefits, as people experience nature in cities and towns. Her research into the human dimensions of open space, urban forestry, and natural systems explores the costs, benefits, and potential ecosystem services of nearby nature. Studies have included perceptions of urban forestry in retail and commercial districts, the integration of urban nature and transportation systems, the human health and wellness benefits associated with the experience of nature, and effective integration of science and policy through technology transfer. She has collaborated with the U.S. Forest Service Pacific NW Research Station to develop a program on urban natural resources stewardship, and is a research advisor to the TKF Foundation.
