Increasing planting stock size by family selection in California ponderosa pine

Government Document
Transfer Guideline: Recommendation

California, USA

This paper describes family differences in 1- and 2-year nursery growth of ponderosa pine from natural stands in the northern Sierra Nevada. Wind-pollinated seed was obtained from 48 parent trees selected in eight stands. The stands sampled four geographic areas-three west and one east of the Sierra crest-to represent climates typical for ponderosa pine. In each area, one stand was selected on a fertile soil and the other on infertile ultramafic soil.
