Urban areas in the conterminous United States doubled in size between 1969 and 1994, and currently cover 3.5% of the total and area and contain more than 75% of the US population. Urban areas contain approximately 3.8 billion trees with an average tree canopy cover of 27%. The extent and variation of urban forests across the 48 states are explored to help build a better understanding of this significant national resource, Urbanization and urban forests are likely to be significant focus of urban forestry in the 21st century. Urban Forest Effects (UFORE0 model has been developed to quantify urban forest structure and selected functions based on field sampling of tree parameters.
