Oregon Forestland Historic Vegetation circa 1850
Return to Forest Atlas main page
Oregon’s forest vegetation is constantly changing as a result of vegetation growth or decay, and natural disturbances such and insects and disease, fire, windstorms, floods, volcanic eruptions, and climate change.
Human alteration of Oregon’s forest predates European settlement, but has increased significantly over the past 150+ years of Oregon statehood. Science does not prescribe a “right” pattern of forest vegetation, but information about the condition of Oregon’s forests in the 19th Century can inform forest management and forest policies today.
