Early Developmental Differences among Five Lodgepole Pine Provenances Planted on a Subalpine Site in Montana

摘要

Lodgepole pine seedlings from British Columbia, Washington, Idaho, and Utah were planted along with a local provenance on a high-elevation site in south-central Montana. After 7 years, survival rates were similar, but growth rankings among provenances have changed. Trees must grow above the winter snow level for a few more years before the performance of each provenance can be clearly characterized.
