The Lost Forest, OR

The Lost Forest Research Natural Area (RNA) contains a remnant stand of an ancient ponderosa pine forest that existed thousands of years ago, when the climate was cooler and supported forest growth over a much larger area. Located over 40 miles from the nearest present day ponderosa forest, the Lost Forest survives on less than 10 inches of precipitation per year. Although ponderosa pine normally required at least 14 inches, the Lost Forest's unique sandy soils trap moisture close to the surface, providing a reservoir that compensates for the lack of rainfall. In order to prevent damage to tree roots and disturbance of the soils upon which the forest depends, OHV use is limited to roads and trails which are posted, "open."
