Tree species rankings based on publication rate (North America)

A ranking of North American tree species based on keyword searches of genus and species using Web of Science, AGRICOLA, and CAB Abstracts. A bibliographic analysis using three bibliographic databases was conducted to understand the importance of North American tree species in literature published since 1900 and since the development of the last Silvics of North America in the 1980s. The Silvics of North America is the most comprehensive guide to North American tree-like species containing about 200 of the 696 tree-like species found in the literature. Depending on the bibliographic database, over 100,000 to over 600,000 publications on the 696 plant species can be obtained. At least half of the publication records are from 1985 forward. The ranking in this database is based on the average rank of six bibliographic searches (three bibliographic databases and two time frames: 1900-2020 and 1985-2020).
