This report details how land cover and urbanization vary within the states of Arizona, Colorado, Idaho, Montana, Nevada, New Mexico, Utah, and Wyoming by community (incorporated and census designated places), county subdivision, and county. Specifically this report provides critical urban and community forest information for each state including human population characteristics and trends, changes in urban and community lands, tree canopy and impervious surface cover characteristics, distribution of land-cover classes, a relative comparison of urban and community forests among local government types, determination of priority areas for tree planting and a summary of urban tree benefits. Report information can improve the understanding, management, and planning of urban and community forests. The data from this report is reported for each state on the CD provided in the back of this book, and it may be accessed by state at: http://www.nrs.fs.fed.us/data/urban.
