The Ecology of the Red River in 1806:
Peter Custis and Early Southwestern
Natural History
DAN L. FLORES*
IN THE COURSE OF AN ADDRESS BEFORE THE PHILADELPHIA LINNAEAN
Society early in 1807, the eminent Pennsylvania professor of natural
history, Benjamin Smith Barton, alluded to the work of a pupil-
Dr. Peter Custis of Virginia-that had been conducted on the Red
River during the preceding year.? Barton did not consider it necessary
to remind this assemblage of northeastern scientists that the young
man whose western natural history survey he mentioned had been the
designated naturalist of President Thomas Jefferson's second major
exploring expedition into the Louisiana Purchase. Perhaps he did
realize, however, that some promotion was essential to prevent his stu-
dent's work from being obscured, even among scientists who ought to
have appreciated it. Already the more dramatic discoveries of Meri-
wether Lewis and William Clark, along with the administration's po-
litical embarrassment at the early abortion of the southwestern ex-
ploration, were combining with the limitations of Custis's work to
erase his important Red River study from American natural history.
The obscurity into which Custis's work soon fell has now prevailed
for more than a century and a half.
The story of Peter Custis's pioneering scientific work in the South-
west, performed nearly two decades before the expeditions of Thomas
Nuttall, Edwin James and Thomas Say, and Jean Louis Berlandier,
