Tree cover is an important element of the urban environments that play an increasingly larger role in ecosystem processes. Urban forests change as trees grow, die, and are replaced. Learn how satellite data is used to make reliable observations about urban tree cover variability and why it matters to urban residents, and explore how these same data are used to map changes in tree cover within the District of Columbia from 1984-2004.
Smithsonian's Stars lectures are suitable for ages 13 and up.
