The designation “Heppner National Forest” does not correspond to any formally recognized unit of the United States National Forest system as documented by the U.S. Forest Service, the National Geographic Society, or other standard reference works. No federal legislation, administrative order, or official map identifies a national forest bearing this name.
The name “Heppner” is most commonly associated with the city of Heppner in Morrow County, Oregon, which was founded in the mid‑19th century and named after early settler Henry Heppner. The surrounding region includes portions of the Umatilla and Ochoco National Forests, but none of these forests have historically been designated as “Heppner National Forest.”
Given the absence of reliable sources confirming the existence of a national forest by this name, the term appears to be either a misnomer, a colloquial reference, or a mistaken conflation of the city of Heppner with nearby federally managed forest lands. Further verification from official forest‑service documents would be required to establish any formal status.
