Effect of seedbeds on germination and survival of Douglas-fir

Creator:

Hermann, Richard K., Chilcote, William W., and Oregon State University. Forest Research Laboratory

Abstract:

Germination and survival of Douglas-fir on seedbeds of unburned, lightly burned, and severely burned soil, charcoal, litter, and sawdust, exposed to 100, 75, and 25 percent of full light, were studied on a south-facing clearcutting in the Coast range of Oregon. Irrespective of exposure to light, germination was best on...

Survival of planted ponderosa pine in Southern Oregon

Creator:

Hermann, Richard K. and Oregon State University. Forest Research Laboratory

Abstract:

Planting techniques, size and age of seedlings, and protection against animals were investigated for their influence on survival of ponderosa pine at two sites in southern Oregon. Caging and mulching with paper were the most effective measures for reducing mortality. Preliminary trials prior to large-scale planting were recommended for determining...
