The raw data used in the Sonoran Desert Plant Atlas is available in the form of fixed-width text data files. Each data file contains entries for only one species, and is named with the species code used in the Sonoran Plant Atlas project. In most cases, this species code is comprised of the first two letters each of the plants genus and species.
Links to the individual data files are organized alphabetically on separate index pages, which can be accessed through the links at the top and bottom of each Sonoran Plant Atlas page. Data codes and field positions used in the raw data files are explained on the Sonoran Plant Atlas Data Definitions page. There are over 2,700 individual data files, although a great number of these contain only a few data points.
The Sonoran Desert Plant Atlas can be ordered from The University of Arizona Press.
