In this Oct. 30, 2019, photo, Joanie Cooper, of the Temperate Orchard Conservancy, compares a rare apple to a 1908 watercolor illustration of the same variety in a U.S. Department of Agriculture book, as she works in her lab in Molalla, Oregon. The apple is a Rhode Island Greening, a heritage variety that was once popular but has now become extremely rare in the U.S. Cooper and her colleagues have helped identify many of the 13 "lost" apple varieties that have been rediscovered in recent years by the Lost Apple Project in eastern Washington and northern Idaho.
