Evaluation of factors associated with reforestation problems on severe sites in the Dead Indian area of southwestern Oregon

Creator:: Williamson, Denis M.
Abstract:: Reforestation of certain areas of southwestern Oregon has become a serious problem. Reforestation failures are evident in numerous clear-cut stands, but failures are also noted in various partially-cut stands. The Dead Indian Plateau, approximately twenty miles east of Ashland, Oregon, has many areas where this is evident. This study investigated...

The reproductive ecology of the pacific yew (Taxus brevifolia nutt.) under a range of overstory conditions in western Oregon

Creator:: DiFazio, Stephen P.
Abstract:: The influence of overstory openness on the reproductive ecology of Pacific yew (Taxus brevifolia Nutt.) was investigated on 4 sites in western Oregon over 2 years. The breeding system of T. brevifolia was found to deviate from pure dioecy under a broad range of canopy and site conditions. Production of...

Growth and reproductive ecology of Larix laricina in interior Alaska

Creator:: Brown, Kevin R.
Abstract:: Larix laricina in Alaska occurs on sites ranging from productive slopes and riverbottoms to wet bogs underlain by permafrost. It is largest on sites without permafrost, where it is associated with Picea glauca, but is much more common in bogs, where it occurs with Picea mariana. In this study, I...

Clearcutting prescriptions based on an environmental classification in the south Umpqua Basin

Creator:: Carkin, Richard E.
Abstract:: Land management techniques are numerous and well known, but knowledge of where and how to use these techniques is often inadequate. Silvicultural methods used by foresters in the Pacific Northwest exemplifies this quandary. Silviculture largely consists of applying standard techniques to various forest stands. Classical silvicultural techniques are not universally...

Thirty-five years of forest succession in southwest Oregon : vegetation response to three distinct logging treatments

Creator:: Arthur, Aaron Stone
Abstract:: This study examined patterns and controls on 35-years of forest succession following logging in the 236 ha South Umpqua Experimental Forest within the Umpqua National Forest in southwestern Oregon. Prior to logging, the overstory in all three watersheds (~50% cover) was composed of Douglas-fir (30-40% cover), grand fir (2 to...

The relation of soil characteristics to growth and distribution of Chamaecyparis lawsoniana and Thuja plicata in southwestern Oregon

Creator:: Imper, David Kimberly
Abstract:: Twelve plots at six sites in southwestern Oregon were studied to determine the degree to which various soil characteristics are related to the occurrence and growth of Chamaecyparis lawsoniana and Thuja plicata. Soil profiles and vegetation were described in each plot, and measurements were made of insolation, soil and litter...

Effects of release from suppression on hydraulic architecture, photosynthetic capacity and functional wood characteristics in Douglas-fir and western hemlock

Creator:: Renninger, Heidi
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), a shade intolerant species, and western hemlock (Tsuga heterophylla (Raf.) Sarg.), a shade tolerant species, were compared to learn more about the temporal pattern of release from suppression in both species, whether hydraulic architecture or photosynthetic capacity constrain release and how wood functional properties change...

The land-water interface : patterns of riparian vegetation and channel morphology in the Oregon Coast Range system

Creator:: Takahashi, Mayumi
Abstract:: This study was conducted to describe variation of riparian vegetation in an Oregon Coast Range system according to geomorphic characteristics and in relation to streamflow. Specific objectives of this study were to: I) examine if the vegetation composition and structure of the riparian forest varied among channel-reach morphologies, 2) examine...

An Interdisciplinary-Botanical Perspective for Cultural Resource Management: A Definition and the Application of Culturally Significant Plants in Identification, Interpretation, and Evaluation for the National Register of Historic Places

Creator:: Burk, Rene F.
Abstract:: Cultivated plants are often living artifacts that can aid in evaluation of historic or cultural landscapes. However, a working definition for “culturally significant plant” is currently lacking in the guidance literature for the cultural resource management practitioners. Based on a review of the literature on cultivated plants as indicators of...
