Evaluation of factors affecting natural reproduction of forest trees in central western Oregon

Creator:: Bever, Dale N.
Abstract:: This study was started in 1947 to investigate the value of various types and quantities of seed source in the establishment of reproduction on cutover land, and to determine the apparent effects of various man-made and natural factors upon the rate of restocking. The man-made and natural factors to be...

Buffer strip dynamics in the Western Oregon Cascades

Creator:: Sherwood, Kim
Abstract:: Although buffer strips have long been used as a protection tool when logging near streams, long-term studies investigating buffer strip dynamics are rare. Steinblums et al. (1984) inventoried 40 buffer strips 1 to 15 years old in the western Oregon Cascades beginning in the summer of 1975. Numerous site and...

Effects of maternal age on reproductive success in black rockfish, Sebastes melanops

Creator:: Bobko, Stephen J.
Abstract:: From 1996 through 1998 I collected mature female black rockfish off Oregon and examined ovaries and otoliths to estimate weekly, age-specific larval production. In all reproductive seasons, older black rockfish extruded larvae earlier in the season, followed by progressively younger fish. Each year, beginning in May, I collected young-of-the-year (YOY)...

Dry coniferous forests in the Western Oregon Cascades

Creator:: Means, Joseph E.
Abstract:: Pseudotsuga menziesii dominates the forests of the Pacific Northwest. But though it is dominat, Tsuaa heteroohylla or Abies amabilis is usually climax. Many researchers have studied Pseudotsuga on the widespread mesic sites where it is seral, but few have examined the relatively rare ecosystems in which Pseudotsuga or its associate...

Understanding names of Oregon trees

Creator:: Leavengood, Scott A. and Oregon State University. Extension Service
Abstract:: It’s little wonder that people are confused by tree names. Foresters and lay people often name a tree based on its physical appearance, the wood products industry may call the tree by another name based on the characteristics of the wood, and botanists name a tree based on its anatomical...

Factors affecting conifer regeneration and community structure after a wildfire in western Montana

Creator:: Toth, Barbara L.
Abstract:: A severe wildfire burned 454 hectares of a second-growth Douglas-fir forest in 1977 on a north-facing slope in Pattee Canyon, near Missoula, Montana. The slope was aerially seeded with a grass mixture, from which Dactylis glomerata established best. Community structure, conifer regeneration, and the impact of the seeded grass on...

A comparative study of temperate Chamaecyparis forests

Creator:: Hawk, Glenn M.
Abstract:: The objectives of this study include: (1) analysis of Chamaecyparis lawsoniana, C. taiwanensis, and C. formosensis forests including the structure, composition, and dynamics of plant communities and their environmental relationships; and (2) comparison of the temperate Chamaecyparis forests of Taiwan and the Pacific Northwest with emphasis on structural and successional...

Nursery, cold storage, and field studies on western conifers inoculated with spores of Pisolithus tinctorius

Creator:: Alvarez, Isabel Fernandez
Abstract:: Inoculations of white fir, Shasta red fir, Douglas fir and ponderosa pine with Pisolithus tinctorius spores when outplanted failed to produce P. tinctorius mycorrhizae at the end of the first growing season. In the third year a few P. tinctorius mycorrhizae were formed on white fir. Inoculations reduced seedling survival...
