"The Changing Mile, " originally published in 1965, was a benchmark
in ecological studies, demonstrating the prevalence of change in a
seemingly changeless place. Photographs made throughout the Sonoran
Desert region in the late 1800s and early 1900s were juxtaposed
with photographs of the same locations taken many decades later.
The nearly one hundred pairs of images revealed that climate has
played a strong role in initiating many changes in the region. This
new book updates the classic by adding recent photographs to the
original pairs, providing another three decades of data and showing
even more clearly the extent of change across the landscape. During
these same three decades, abundant information about climatic
variability, land use, and plant ecology has accumulated, making it
possible to determine causes of change with more confidence. Using
nearly two hundred additional triplicate sets of unpublished
photographs, "The Changing Mile Revisited" utilizes repeat
photographs selected from almost three hundred stations located in
southern Arizona, in the Pinacate region of Mexico, and along the
coast of the Gulf of California. Coarse photogrammetric analysis of
this enlarged photographic set shows the varied response of the
region's major plant species to the forces of change. The images
show vegetation across the entire region at sites ranging in
elevation from sea level to a mile above sea level. Some sites are
truly arid, while others are located above the desert in grassland
and woodland. Common names are used for most plants and animals
(with Latin equivalents in endnotes) to make the book more
accessible to non-technical readers. The original "Changing Mile"
was based upon a unique set of data that allowed the authors to
evaluate the extent and magnitude of vegetation change in a large
geographic region. By extending the original landmark study, "The
Changing Mile Revisited" will remain an indispensable reference for
all concerned with the fragile desert environment.
