Abstract:
... With the move to intensive forest management to meet wood demand and to preserve the environment, southeast Alaska is experiencing a period of significant change in terms of wood characteristics or wood quality. In order to responsibly manage the young-growth stands, it is important to evaluate tree quality prior to harvest and understand the product and economic potential of the wood fiber in sta ...

Abstract:
... Poor growth of conifer regeneration occurred on sites formerly occupied by old-growth cedar-hemlock (CH) forests in coastal British Columbia, 5-8 years after clearcutting and slashburning. Symptoms included chlorotic foliage and growth check of Sitka spruce, western hemlock, western red cedar and amabilis fir, coincident with the expansion of the ericaceous shrub, salal, on the cutovers.

Abstract:
... Red alder (Alnus rubra Bong.) commonly dominates the overstory in managed riparian forests of the Pacific Northwest. Although it is assumed that competition with a dense shrub layer inhibits succession from hardwoods to shade-tolerant conifers within these forests, this assumption has not been explicitly tested. We hypothesized that seed availability rather than competitive interactions largely sh ...
