Gentry's Rio Mayo Plants: The Tropical Deciduous Forest & Environs of Northwest Mexico (Southwest Center Series)

Summary: Hidden treasure
Review: I was given the opportunity to catalog Dr. Gentry's herbarium collection at the Desert Botanical Garden in 1987-88. I haven't seen the new edition mentioned here, but read the original work at the time I was cataloging his herbarium specimens. Through it, I was able to share his experience as an explorer in the spirit of John Wesley Powell, someone who knew that the American southwest is best delineated by watersheds, not along false lat/long lines. I met Dr. Gentry a couple of times, and remember the occasions well. Last time I saw him, when I was cataloging his collection, I overheard a conversation between him and a consultant for the Fort McDowell Indian Community. The consultant was asking about desert-adapted crop plants. Dr. Gentry went into great detail describing many desert plants suited to agriculture - tepary beans, jojoba, Lippia (Mexican oregano), agave, chiltepines, gum arabic, etc. I learned a lot just by eavesdropping. The consultant listened, but did not hear the words. He recommended that the Fort McDowell people plant cotton. Not because it was best suited to desert agriculture - far from that. They planted cotton because it needs vast quantities of water. They did not want the best desert-adapted crops. What they wanted, instead, was the best crop for wasting water, so that they could establish valid rights to the water. Worse, I watched them clear off vast acreages of mesquite forests to make room for the water-wasting cotton crop. The Hopi call this koyaanisqatsi. This book should help folks in southwestern north America realize that we have a bounteous resource, if we can only learn to use it.

Summary: Excellent reference book
Review: Located in a transition zone between the Sonoran Desert and the tropics,this region is well known for its biodiversity, thanks to a 1942 study by botanist Howard Scott Gentry. Revision of his classic work began before his death in 1993. For researchers, this is a must-read book. It provides a clear overview of botanical studies of the Rio Mayo, a contemporary view of the vegatation, excerpts from the original text and an annotated list of plants.
