Early U.S. Forest Service timber inventories began around 1907–1908. By 1911–1916, underestimation and unreliability were commonly known, by 1926 abandonment was suggested, and by the 1930s they were replaced by better methods. Hagmann et al. Comment (2018; “Hagmann et al.” hereafter) and other recent users of these data appeared unaware of this history and assumed these data were accurate, but these data had been documented for a century to be unreliable and to underestimate tree density and timber volume. There is no disagreement between Hagmann et al. and Baker and Hanson (2017; “B&H” hereafter) regarding most of the central findings of B&H, including this history, most of our corroboration of underestimation by early timber‐inventory data, and our documentation of omission of key available data in recent uses.
