We thank Nathan Hartley and Harrison Wallace for assistance in
the field during the locality verification efforts, as well as Mark
Olszewski, Matt Snyder, Andrew Bonsall, Cameron Andrews, and
Daniel Kral for work as student programming interns. We also
thank Kevin Faccenda for his assistance in curating student collections and for critically reviewing an earlier draft of this manuscript.
Chris Firestone provided helpful consultation regarding legal and
ethical restrictions on plant collecting. We also appreciate Beth
Roberts, our Biology Department Secretary, for securely keeping
anonymous student survey forms until after each semester was
complete. We appreciate support from a Millersville University Faculty Development Grant to CRH, as well as a PASSHE Research
Grant to NWH and CRH. Finally, we greatly appreciate Millersville
University and, most importantly, the generations of Millersville
Faculty for their stewardship of the Millersville University Biological Preserve and its predecessor, The Bush, in which a substantial
proportion of this research was conducted.

CRH and NWH conceived of and directed the design of NatureAtlas.org.
CRH was the course instructor responsible for the design, implementation
and grading of the plant collection projects and anonymous student surveys
reported on in this study. Both CRH and NWH were responsible for compiling
relevant statistics and for writing this article.
