The effects of partial cutting on stand structure and growth, and forest plant communities of western hemlock-Sitka spruce stands in southeast Alaska

Creator:

Deal, Robert L.

Abstract:

This study evaluated the effects of partial cutting on stand structure and growth, patterns of conifer regeneration, stand mortality and disease, and understory plant diversity and abundance. Seventy-three 1/5 ha plots were established in 18 partially cut stands throughout southeast Alaska. These stands were partially cut 12 to 96 years...

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...

Sitka spruce and western hemlock regeneration after selective harvesting, Tongass National Forest, southeast Alaska

Creator:

Yount, Louise Simmons

Abstract:

The objectives of this study were to determine the species composition and density of natural conifer regeneration following selective logging in southeast Alaska. Therefore, we quantified the density and size of new cohort spruce and hemlock and current seedling bank in 17 selectively logged stands. All stands were in mixed...
