Fruit Detectives Search For Rare Kinds of Apples

An apple tree stands alone near the top of a hill. It produces the Arkansas Beauty, a fruit long believed to have disappeared from existence. Three years ago, plant experts E.J. Brandt and David Benscoter rediscovered it.

The men have found 13 long-lost apple varieties in an area once known as Oregon Territory in the northwestern United States.

Brandt and Benscoter, both retirees, lead a nonprofit called Lost Apple Project. They travel hundreds of kilometers in trucks and on foot to find orchards² planted by settlers more than a century ago.

The two are racing³ against time to keep the fruit from disappearing. The apple trees are old, and many are dying. Others are being ripped out for more wheat fields or housing developments.

"To me, this area is a goldmine," said Brandt, who has found two historical varieties in the state of Idaho. "I don't want it lost in time. I want to give back to the people so that they can enjoy what our forefathers⁵ did."

History

North America once had 17,000 named varieties of domesticated⁷ apples, but only about 4,000 remain. The Lost Apple Project believes settlers planted a few hundred varieties in their part of the Pacific Northwest alone.

The Homestead Act of 1862 gave 65 hectares to families who would improve the land and pay a small fee. These people planted orchards with enough variety to get them through the long winter. They planted apples that ripen⁸ from early spring until the first freeze.

Then, as now, people did not raise apples from seeds. People took cuttings taken from existing trees and then joined them with roots. The new trees do not have the genetic⁹ material that often makes "wild" apples unfit as food.

Genetic Diversity

Joanie Cooper is a plant scientist at the Temperate¹⁰ Orchard¹ Conservancy. She has helped identify many of the lost varieties found in northern Idaho and eastern Washington. The trees have value beyond their historic importance, she notes.

The trees could help genetic diversity among modern-day apple crops as climate change and disease take an increasing toll¹¹.

Cooper said, "You have to have varieties that can last, that can grow, produce fruit, survive the heat and maybe survive the cold winter, depending on where you are. I think that's critical."
