Structural development of late successional forests in the central Oregon Coast Range : abundance, dispersal, and growth of western hemlock (Tsuga heterophylla) regeneration

Creator:

Schrader, Barbara A.

Abstract:

Patterns of western hemlock regeneration were studied in relation to forest structural development and environment in the Oregon Coast Range. Density of western hemlock seedlings was examined across the climatic gradient from cool, moist coastal areas to the seasonally hot and dry Willamette Valley Margin. Seedling densities were most strongly...

Tree seedling establishment on heterogenous microsites in Douglas-fir forest canopy gaps

Creator:

Gray, Andrew N.

Abstract:

Tree seedling establishment and growth were studied in experimental canopy gaps to determine the effect of structural and environmental heterogeneity on species dynamics within mature and old-growth Douglas-fir forests in the Cascades of central Oregon and southern Washington. Factors examined included forest age, gap size, within-gap position. substrate, year of...
