    Description

    Young-growth ponderosa pine seed trees were evaluated in terms of seed production. Seed trees ranging from 3 to 9 per acre produced 5,000 to 35,000 seeds per acre in years of moderate and heavy cone crops. Seed-tree selection before harvesting by the seed-tree method of cutting must be keyed to evidence of past cone production to assure best seed production in the future.
