The mycorrhizal associations of western hemlock

Creator:: Kropp, Bradley Ray
Abstract:: Two objectives of this research were to identify fungi which are mycorrhizal with western hemlock and to examine the ecology of hemlock mycorrhizal fungi indigenous to outplanting sites. Another objective was to evaluate the effectiveness of mycorrhizal inoculation in improving the performance of outplanted hemlock seedlings. A list of over...

Genetic considerations in cloning western hemlock

Creator:: Foster, George Samuel
Abstract:: Using clones to regenerate a species new to clonal reforestation presents the forest manager with many problems. A number of interrelated and interdependent research and development activites are needed to answer these technical questions. Network diagraming was used for scheduling research activities and for indicating interdependencies among activities. The resultant...

Provenance variation in Western hemlock (Tsuga heterophylla (Raf.) Sarg.) seedlings

Creator:: Kuser, John E.
Abstract:: A range-wide sample of 221 provenances of western hemlock (Tsuga heterophylla (Raf.) Sarg.) showed much variation in several characteristics. Variation in seed weight was significant, but not correlated with seed source latitude, elevation, or distance from the ocean. Variation in the frequency of 4-cotyledon seedlings was significant at regional, provenance,...

Growth of western hemlock stands after precommercial thinning

Creator:: Dilworth, J. R. (John Richard), 1914- and Oregon State University. Forest Research Laboratory
Abstract:: Young western hemlock stands in the Coast Range of Oregon will contribute to the commercial timber supply of the region in the future, the extent of the contribution depending on environmental and cultural factors. The relative diameter and volume growth of crop-trees in the stands will be increased substantially by...

Logs as sites of tree regeneration in Picea sitchensis-Tsuga heterophylla forests of coastal Washington and Oregon

Creator:: Harmon, Mark E.
Abstract:: Logs are seedbeds for trees in many Picea sitchensis-Tsuga heterophylla forests of Washington and Oregon. Factors affecting this close association, including seed retention and seedling establishment on logs and successional changes in log characteristics, are explored In this study. Field and laboratory experiments indicated that competition with vegetation on the...

Carbohydrates in a thermomechanical pulp, a sulfite pulp, and a solvent sulfite pulp from western hemlock

Creator:: Ni, Hae-Rong
Abstract:: A thermomechanical pulp, a high yield sulfite pulp, and a high yield solvent sulfite pulp from western hemlock [Tsuga heterophylla (Raf.) Sarg.] wood were investigated to determine the amount of carbohydrate material present and to elucidate the structures of the carbohydrates. The effects of the three pulping processes, which were...

Factors affecting nitrogen nutrition of western hemlock

Creator:: Gill, Ranjit Singh
Abstract:: Preliminary fertilization trials with western hemlock have yielded responses which vary significantly from stand to stand, especially in areas near the Pacific Coast. Growth responses have varied from positive to negative in an erratic manner. Previous data did not permit validation of such hypotheses as, "the application of fertilizer to...

Biomass dynamics of dead Douglas-fir and western hemlock boles in mid-elevation forests of the Cascade Range

Creator:: Graham, Robin Lee Lambert
Abstract:: The rate and manner of bioniass loss from decomposing Douglas-fir and western hemlock boles in mid-elevation forests of the central Cascade Range were measured. Bole bark and wood were considered separately. Loss of bole wood due to respiration was measured by change in bole wood density. Loss of bole wood...

A stand management strategy for young western hemlock-Sitka spruce forests

Creator:: Kellogg, L. D. (Loren D.)
Abstract:: Western hemlock-Sitka spruce forests, where prior precommercial thinning has occurred, constitute one of the most productive young-growth management types along the Pacific Coast from Oregon to southeast Alaska. These stands are ready for a first commercial thinning entry, however, the costs and benefits of such entries and resulting impacts at...
