Dynamics of Urban Forest Cover in the Age of Humans

This lecture is part of the monthly Castle Lecture Series hosted by the Smithsonian's Grand Challenges Consortia.

Dr. Andrew Johnston
National Air & Space Museum
November 19, 2013
Noon – 1:00pm EDT

Urban forests are increasingly of interest as urbanized populations grow and urban areas expand. The majority of humans globally now live in urban settlements and the urban population is growing faster than the total population. Urban ecosystems have become a focus of research, and better understanding of how tree cover is a variable land cover component of the urban environment will enhance knowledge of these ecosystems. Utilization of archival satellite remote sensing data provides an opportunity to understand historic changes in urban vegetation cover. New research has made reliable measurements of urban tree cover variability over decadal periods in large urban centers including the District of Columbia, and investigated linkages with spatial patterns of urban land use. These observations are providing new perspectives for the management of urban resources and in efforts to understand how human settlements play a role in ecosystem processes.
