Trees are listed alphabetically by family and then alphabetically by genera when more than one species was requested in the genus or when the genus comprised 100 or more of the total requests for the 2005 planting survey. Requests for 2000 are in regular text and the 2005 requests are bolded. Families are subtotaled in bold italics when there were two or more genera in them. When data were not collected in one survey but were in another, N/A is substituted for missing data.
