Description: The Bureau of Land Management initiated a tree improvement program in 1965 to increase the volume of wood production from 1.9 million acres of public forests in western Oregon.  The plan called for 233 test plantations to select genetically superior parent trees and 4 seed tree orchards to produce genetically improved tree seed for reforestation programs on BLM lands.--Page [1].
