the management of ponderosa pine are reviewed; issues that likely will affect the future management of ponderosa pine systems are listed; and critical gaps in our understanding of ponderosa pine silviculture that may affect our management in the near term are identified.
Ponderosa pine forests are widely distributed in eastern Oregon, ranging in elevation from 2,500 to 6,000 feet. Ponderosa pine found in the Willamette valley is actually genetically very different than eastern Oregon ponderosa.
