Visual Definitions on the Web
Welcome to our homepage. This page has been designed to aid people in their understanding of the basic terminology used in dichotomous keys and in tree anatomy. As residents of the Pacific Northwest, the terms and the plants we have concentrated on are those that are prominent in this area. This page was constructed as a term project for Forest Biology (BI 307) at the University of Oregon. The 22 identified species on this page correspond to the species that students of BI 307 class are required to know by sight. This page was also designed to assist students of Environmental Education (PEOL 453).
Hopefully this will act as a guide and a supplement to provide visual images and explainations that written definitions cannot. Good luck!
This page was constructed by Tony Leiserowitz, Shana Pennington and Indigo Teiwes under the advisory of Alan Dickman. If you have any questions or comments please contact Alan Dickman at adickman@oregon.uoregon.edu.
