DescriptionSeed trees were selected in young-growth ponderosa pine to produce an estimated 25,000, 50,000, and 100,000 seeds per acre. A year after a good seed crop, ponderosa pine stocking in cutover plots was: 1,910, 4,020, and 4,820 seedlings per acre. Some additional regeneration of other species also occurred.
