Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is one of the world's most important and valuable timber trees. Its natural distribution in North America resembles an inverted V with uneven sides. From the apex in British Columbia, the western half extends along the Pacific mountain ranges into California for about 2,200 km...

Creator:: Hermann, Richard K., Lavender, Denis P., Zaerr, Joe B., and Oregon State University. Forest Research Laboratory
Abstract:: Reforestation sometimes is delayed by planting seedlings that do not have high potential for survival. Several factors influence survival. Unstored Douglas-fir lifted and planted in early fall generally are increasingly harmed by moisture stress the farther south in the Douglas-fir region they are. Such early-lifted seedlings are harmed even more...

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...

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...

Resource Type:: Technical Report

Creator:: Hermann, Richard K., Lavender, Denis P., and Oregon State University. Forest Research Laboratory
Abstract:: "We describe a test procedure developed during growth room and field trials for which we processed hundreds of test lots of seedlings, mainly Douglas-fir (Pseudotsuga menziesii) and ponderosa pine (Pinus ponderosa), as well as lodgepole pine (Pinus contorta), Jeffrey pine (Pinus jeffreyi), and Sitka spruce (Picea sitchensis), noble fir (Abies...
