BACKGROUND: Every city and town is obligated to maintain the safety of public trees along its streets and roads and in its parks. Where there are trees, there are problems and defects— some natural, some man-made. Limited municipal funding and tight eco- nomic times make it more important than ever that public officials and private con- sultants know how to prioritize tree care in the urban environment.
