In 2014 Dr. Terry presented two well-received public talks on the potential role of cultivation in the conservation of Lophophora williamsii.

"Authorized consumption without authorized cultivation: effects of the absence of regulatory structure in the conservation of Lophophora williamsii." 33rd IOS Congress, 8–11 April 2014, Tucson, Arizona.
[IOS talk abstract]
So far as we know the talk was not recorded. We are making available the presentation notes that were used as a basis for both talks. The IOS Congress was limited to 15 minutes with questions. The one at Toluca was longer and was in Spanish.

A number of errors were introduced into our chapter after both the authors and the editors had performed final proofing. It is otherwise a beautiful and interesting book.
And a suggestion for another valuable reference work:
“TAXONOMY of the CACTACEAE” by Joël Lodé presents a welcomed revision of Cactaceae. The two volume work is available at Cactus Adventurers.
An index of the recognized species and synonyms is available online as a free PDF. While it would be possible to link directly to that PDF we felt that our readers would benefit from having a link to the page containing that link as it also includes full details about the book Taxonomy of the Cactaceae, an image gallery of cactus seeds and information about Cactus Adventurers. https://cactus-aventures.com/pageweb_ENG.html
