Survival and Height Growth of Coastal and Interior Western White Pine Saplings in North Idaho

摘要

Western white pine saplings from the Olympic Peninsula of Washington and from north Idaho sources planted together in north Idaho did not differ in their survival rates. There has been no visual evidence of freezing injury to either group. At age 12, height of the coastal saplings generally falls within the height range for north Idaho saplings. The findings lend support to earlier results, which indicated that most of the variation in north Idaho white pines is found within, rather than between populations.
