An uneven-aged, understocked virgin forest of ponderosa pine (Pinus ponderosa Laws.) was partially harvested by group selection, improvement selection, and salvage cutting.

The conventional cutting systems suggested for the future will lead to even-aged stands where present stand structure will permit, and to group selection stands where present structure is many-aged.
