Species Lost

This is a preliminary checklist of species lost from the central campus and arboretum area. The Source column indicates which sources had noted the species. (The 2024 update includes specimens noted in the faculty residential area when determining species status.)

Species to watch, i.e. species very rare on campus, are also noted. Sometimes campus lost a species but regained it years later; these cases are also noted.

• The checklist was created 28 May 2003 by John Rawlings, using the various sources noted in the Source legend below.
• The checklist was updated 28 July 2024 by Sairus Patel. The status of the species was noted by the colored indicators. TOS24 was added as a source reference in the legend. The latest accepted scientific names of some plants were noted. No additional plants were added to the list, however. For example, the last Picea orientalis specimen on campus was removed in early 2024, but since the species did not appear in historical sources used, it is not mentioned on this list.

Species status legend:
As of July 2024 survey (TOS24):
🔴 = Lost.
🟠 = To watch or rare (1 or 2 specimens).
🟢 = Had been indicated as lost or rare but has been replanted or found (3 or more specimens).
