Urban FIA is the permanent establishment of plots and annualized inventory of trees in community settings to provide information on the status and trends of urban trees and forests over time. In addition to the plot data, UFIA administers the Urban National Landowner Survey (research.fs.usda.gov/programs/nwos) in some cities. Urban Forest Stats is available through a partnership between the USDA Forest Service and Texas A&M Forest Service. Many of the estimates rely on i-Tree methods and processing (www.itreetools.org).
