Cone and Seed Insects at Big Fork Tree Improvement Area.

摘要

Insects that feed on cones and seeds are common in our forests and can often become “pests” in seed orchards where high value seed is collected from genetically superior trees. Douglas-fir and western larch trees at Big Fork Tree Improvement Area (TIA) are now producing valuable seed for reforestation. Demand for seed from east side Douglas-fir and mid- and high elevation western larch is high and the Big Fork TIA is expected to provide seed for a large portion of western and central Montana.
