The Pecan: A History of America's Native Nut
by James McWilliams
The University of Texas Press, 2013
ISBN 978-0-292-74916-0
Hardcover pp. 192
Crisply entertaining and chock-full of crunchy research by a food historian, this apparently delicious little book on America's native nut— (and isn't the cover charming?)— is a horror story.
It opens, as the darkest do, with a sunny scene of innocence. Clustered along river bottoms in what would one day become Texas, groves of pecan trees rained down their bounty for wildlife and indigenous peoples. For centuries, pecans were their superfood, dense with calories and nutrition. In the 16th century, Alvar Nuñez Cabeza de Vaca, the conquistador who shipwrecked en route to Florida and wandered west, found the Guadalupe River "a river of nuts"— although he had no word for them but "walnut." The name "pecan" dates from the late 18th century.

Farmers found wild pecans not only delicious as snacks for themselves, but good pig feed, and bags of them, easily gathered, could be sold in new markets in San Antonio, Galveston, and New Orleans. In the second half of the 19th century, Texas took the lead in pecan production, but not from formal orchards; for the most part, farmers gathered wild pecans.
How to sell more pecans? The market wanted uniformity, thin shells, and dense nut meats. Even the most magnificent pecan tree's seed, however, would not "come true," that is, bring forth a tree producing equivalent quality nuts. The solution was grafting. As early as 1822 one Abner Landrum detailed his own successful experiments with pecan grafting in the American Farmer. It seems no farmer bothered to emulate that experiment. The market for pecans was still marginal and, as McWilliams ventures, "it was simply more macho to run a ranch with cattle than to turn that land over to pecans."

For a time, farmers relied on wild pecans, resisting experts' advice to graft pecans, perhaps out of innate conservatism and a reluctance to becoming dependent on nurserymen. Attitudes soon changed. After a series of insect plagues in the last three decades of the 19th century decimated major cash crops, the USDA championed chemical insecticides that, "lo and behold, worked." Writes McWilliams, "The USDA was no oracle, but as pecan farmers recognized, history showed it could make life much easier for those who tilled the soil for a living. So long as they would listen." Listen they did.
The 20th century brought increasing industrialization in pecan production. After World War I, writes McWilliams, "pecan trees were becoming carefully managed commodities rather than natural aspects of the southern landscape." As for shelling, an important source of employment in San Antonio in the 30s, after some labor unrest, this was given over to machines.
In World War II the U.S. government gave the pecan industry a push, promoting the nuts as nutritious replacements for meat; and after imposing price ceilings to help promote consumer demand, buying up millions of pounds of surplus pecans (many fed to schoolchildren). By the late 1940s, pecans were no longer holiday treats or just for pralines, they were in everything from cakes to cookies to pies, even salads. McWilliams: "The aristocrat of nuts had become a commoner."
McWilliams brings the pecan through the rest of its 20th century history with mail order, frozen foods, processed foods, chain restaurants, granola, and ice cream; its oil extracted for lubricants in clocks and guns, its wood milled for basketball court flooring, its shells collected for mulch, barbecue chips, plywood, pesticides, and more. By 2011, when the author tours a Texan pecan farm, he is stuck with dark wonder:
"First, the entire operation is a streamlined model of mechanization. Vehicles designed to fit snugly between seemingly endless rows of perfectly aligned pecan trees spray pesticides, herbicides, and fungicides; they lay mulch, prune trees, apply fertiziler, and harvest nuts. Other machines disk the soil and smooth the turf between the trees so that fallen nuts do not elude harvest. At times helicopters are even brought in for the purpose of keeping frost from icing the nuts. Propane cannons are on hand to scare off crows. It occurred to me as we drove from orchard to orchard that there was nothing 'natural' about a contemporary pecan orchard. I was looking at a factory in the field."

The future of the pecan, a "chemically saturated activity," whether in the U.S. or China or elsewhere, looks grim. Arsenals of insecticides are increasingly necessary to combat aphids, beetles, weevils and more. These chemicals also threaten bees and other pollinators (and without them, our food supply as we know it may collapse). Plant diseases are also becoming increasingly resistant to chemical assault. The soil degrades. At some point— perhaps when China has become the top producer; perhaps when some insect or fungus has wiped out enough orchards; or in the wake of some ecological or economic jolt— it may become unprofitable to continue producing pecans in the U.S., the grafted and chemically attended ones for the mass market, that is. What then will have become of the now few stands of wild pecans? The good intentions of many decades—ye olde single-minded "economic development"— have brought this once thriving wild nut tree to a state of such fragility that, concludes McWilliams, "we may well lose yet another natural thread to the past."
