Propwash treatments from a low-flying Bell 47-G2 helicopter dislodged few spruce budworm larvae and pupae from host balsam-fir trees. After propwash treatments, both larval-pupal densities on branch samples and in drop-tray collections near the ground were not significantly different between treated and control plots. Significantly more larvae were found in the lower crowns of treated trees, possibly indicating a downward shift in the larval population due to treatment. Residual parasitized larvae was 15.9 percent on treated trees and 14.6 percent on control trees.

Reports average stumpage and roadside prices and their relative rates of change for timber and logs in New Hampshire for 1964 to 1983. Stumpage and roadside prices increased overall from 1964 to 1983. Roadside prices increased at a slower rate than stumpage prices. Real sawtimber prices increased for all species except hemlock during the period. Red oak prices increased at the greatest rate. Hardwood-pulpwood stumpage prices increased over the study period while spruceifir and other softwood- pulpwood stumpage prices decreased in real terms. For the 20- year period, harvest cost for...

Part 1 of 2.

Provides a regional prospective on resources, problems, and trends related to biomass harvesting in the Northeast.

Describes natural history profiles of New England wildlife species and their associations with forested and nonforested habitats. Provides a database that will enable forest managers or wildlife biologists to describe the species or groups to be found in a given habitat.

Contains 23 papers presented in six technical sessions on forestry research management planning and evaluation. Primary topics focus on nontraditional views and sources of information and emerging technologies affecting forestry research; methods for identifying research needs and strategies required for implementation; and research evaluation at the individual, program, and organizational levels.
